Hybrid seed production and marketing advances

“My goal is to produce and sell 200 metric tons of hybrid maize by 2025,” says Subash Raj Upadhyaya, chairperson of Lumbini Seed Company, based in Nepal’s Rupandehi district.

Upadhyaya is one of the few seed value chain actors in the country progressing in the hybrid seed sector, which is at a budding stage in Nepal. He envisions a significant opportunity in the domestic production of hybrid maize seed varieties that not only offer a higher yield than open-pollinated varieties but will also reduce expensive imports. Leaping from one hectare to 25 hectares in hybrid maize seed production within three years, Upadhyaya is determined to expand the local seed market for hybrids.

Nepal has long been a net importer of hybrid seeds — mainly rice, maize and high-value vegetables — worth millions of dollars a year to meet the farmers’ demand, which is continuously rising. Although hybrid varieties have been released in the country, organized local seed production and marketing were not in place to deliver quality seeds to farmers. The hybrid variety development process is relatively slow due to lack of strong public-private relationships, absence of enabling policies and license requirements for the private sector to produce and sell them, lack of suitable germplasm and inadequate skilled human resources for hybrid product development and seed production. This has resulted in poor adoption of hybrid seeds, especially maize, where only 10-15% out of 950,000 hectares of Nepal’s maize-growing area is estimated to be covered with hybrid seeds, leaving the balance for seeds of open pollinated varieties.

This is where experts from the International Maize and Wheat Improvement Center (CIMMYT) have stepped in to unlock the untapped potential of domestic maize production and increase on-farm productivity, which is currently around 2.8 metric tons per hectare. Aligning with the goals of the National Seed Vision (NSV 2013-2025), the USAID-funded Nepal Seed and Fertilizer (NSAF) project, implemented by CIMMYT, fosters private sector involvement in the evaluation, production and marketing of quality hybrid seeds to meet the growing domestic demand for grain production, which is currently being met via imports. In 2020, Nepal spent nearly $130 million to import maize grain for the poultry industry.

Teach a man to fish

Strengthening and scaling hybrid seed production of different crop varieties from domestic sources can be a game-changer for the long-term sustainability of Nepal’s seed industry.

Through the NSAF project, CIMMYT is working with eight partner seed companies and three farmers cooperatives to produce seeds of maize, rice and tomato. CIMMYT has played a vital role in making suitable germplasms and market-ready products of hybrids sourced from CGIAR centers available to the Nepal Agricultural Research Council (NARC) and partner seed companies for testing, validation and registration in the country. But this alone is not enough.

The project also carried out the partners’ capacity building on research and development, parental line maintenance, on-station and on-farm demonstrations, quality seed production and seed quality control to equip them with the required skills for a viable and competitive hybrid seed business. The companies and farmer cooperatives received hands-on training on hybrid seed production and marketing coupled with close supervision and guidance by the project’s field staff assigned to mentor and support individual seed companies. CIMMYT’s NSAF project also provides financial support to selected hybrid seed business startups to enhance their technical and entrepreneurial skills. This is a new feature, as prior to the project starting nearly all of the seed companies were mainly involved in aggregating open-pollinated variety seeds from farmers and selling them with no practical experience in the hybrid seed business.

In 2018, CIMMYT, through the NSAF and Heat Stress Tolerant Maize for Asia (HTMA) projects, and in close collaboration with NARC’s National Maize Research Program, engaged its partner seed company to initiate the first hybrid maize seed production during the winter season. Farmers’ feedback on the performance of the Rampur Hybrid-10 maize variety showed it could compete with existing commercial hybrids on yield and other commercial traits. As a result, this response boosted the confidence of seed companies and cooperatives to produce and market the hybrid seeds.

“I am very much motivated to be a hybrid maize seed producer for Lumbini Seed Company,” said a woman hybrid seed grower, whose income was 86% higher than the sale of maize grain from the previous season. “This is my second year of engagement, and last year I got an income of NPR 75,000 (approx. USD$652) from a quarter of a hectare. Besides the guaranteed market I have under the contractual agreement with the company, the profit is far higher than what I used to get from grain production.”

To build the competitiveness of the local seed sector, CIMMYT has been mentoring partner seed companies on business plan development, brand building, marketing and promotion, and facilitating better access to finance. As part of the intervention, the companies are now selling hybrid seeds through agro-dealers in attractive and suitable product packages of varied sizes designed to help boost seed sales, better shelf life and compete with imported brands. They have also started using attractive seed packages for selected open-pollinated rice varieties in a bid to increase market demand. Prior to the project’s intervention, companies used to sell their seeds in traditional unbranded jute bags which are less suitable to maintain seed quality.

Unite and conquer

Encouraging public-private partnerships for seed production is crucial for creating and maintaining a viable seed system. However, the existing guidelines and policies for variety registration are not private sector friendly, resulting in increased informal seed imports and difficulty to efficiently run a business. This draws attention to conducive policies and regulations patronage in research and varietal development, product registration, exclusive licensing, and seed production and marketing by the private sector.

CIMMYT supports the Seed Entrepreneurs Association of Nepal (SEAN), an umbrella body with more than 2,500 members, to promote the private sector’s engagement in the seed industry and foster enabling policies essential to further unlock Nepal’s potential in local hybrid seed production and distribution. Together, CIMMYT and SEAN have facilitated various forums, including policy dialogues and elicitations on fast track provision of R&D license and variety registration by the local private seed companies. These are vital steps to realize the targets set by NSV for hybrid seed development and distribution.

To further enhance linkages among seed sector stakeholders and policy makers, CIMMYT, in coordination with NARC’s National Maize Research Program, organized a high-level joint monitoring field visit to observe hybrid maize seed production performance in April 2021. As part of the visit, Yogendra Kumar Karki, Secretary of the Ministry of Agriculture and Livestock Development, accompanied by representatives from the National Seed Board, National Planning Commission, Ministry of Finance, NARC, Seed Quality Control Center and SEAN, interacted with seed grower farmers and seed companies on their experiences.

The trip helped build a positive perception of the private sector’s capability and commitment to contribute to Nepal’s journey on self-reliance on hybrid seeds. “The recent advances in hybrid seed production by the private sector in collaboration with NARC and NSAF is astounding,” said Karki, as he acknowledged CIMMYT’s contribution to the seed sector development in Nepal. “Considering the gaps and challenges identified during this visit, the Ministry will revisit the regulations that will help accelerate local hybrid seed production and achieve NSV’s target.”

In continued efforts, CIMMYT is also partnering with the government’s Prime Minister Agricultural Modernization Project (PMAMP) maize super zone in the Dang district of Nepal to commercialize domestic maize hybrid seed by partner seed companies. This will enable companies to invest in hybrid maize seed production with contract growers by leveraging the support provided by the PMAMP on irrigation, mechanization and maize drying facilities.

“Our interventions in seed systems integration and coordination are showing very promising results in helping Nepal to become self-reliant on hybrid maize seeds in the foreseeable future,” said AbduRahman Beshir, seed systems lead for the NSAF project. “The initiative by the local seed companies to further engage and expand their hybrid seed business is an indication of a sustainable and viable project intervention. The project will continue working with both public and private partners to consolidate the gains and further build the competitiveness of the local seed companies in the hybrid maize seed ecosystem.”

Nepal’s seed industry is entering a new chapter that envisages a strong domestic seed sector in hybrid seed, particularly in maize, to capture a significant market share in the near future.

Hands-on experience in seed production

Recently, a group of 40 postgraduate students from Nepal’s Agriculture and Forestry University (AFU) were able to learn first-hand about hybrid maize seed production in a field site managed by a partner seed company of the International Maize and Wheat Improvement Center (CIMMYT). Bringing in a whole new and rare experience altogether, the students got a glimpse of the progress and challenges of the seed industry as of today.

The field trip followed the development of a revised curriculum for AFU’s Seed Science and Technology program, initiated in November 2019, which stresses the importance of creating linkages between university students and private seed companies. Through the USAID-supported Nepal Seed and Fertilizer (NSAF) project, CIMMYT is working towards enhancing partnerships between agricultural universities and the seed industry, and revisiting the curriculum has been the first stepping stone.

In collaboration with AFU and Lumbini Seed Company, CIMMYT organized an off-campus participatory learning experience to enrich students’ understanding of hybrid seed production initiatives by the private sector and the opportunities that lie in the various business models of Nepalese seed companies. The initiative is part of a concerted effort by CIMMYT and its partners to alleviate the critical limitations of skilled manpower in the industry.

A deep dive into hybrid seed

The program began with an on-site briefing on the recent developments of hybrid seed production by the private sector.

“Nowadays, farmers are increasingly demanding hybrid seeds over open-pollinated varieties due to their higher yields,” explained Subash Raj Upadhyaya, Managing Director of Lumbini Seed Company. This seed demand is almost entirely met via imports.

Since 2018, the company has been successful in producing and marketing hybrid maize seed such as Rampur Hybrid-10, a variety originally sourced from CIMMYT and released in Nepal by the National Maize Research Program with technical and financial support from the NSAF project. Going from one hectare to 25 hectares of hybrid maize seed production in the course of three years, Lumbini Seed Company has demonstrated the capability of local private seed companies building up the country’s capacity in this area.

“The collaboration between public and private seed stakeholders is helping Nepal to realize hybrid seed self-reliance in the foreseeable future,” explained AbduRahman Beshir, seed systems lead for the NSAF project at CIMMYT. “What is needed is competitive products augmented by quality seed production and effective marketing strategies.”

Beshir described the important stages of seed production and the components of robust seed systems, while Hari Kumar Shrestha, a seed systems officer at CIMMYT, detailed the requirements for quality seed production and certification of hybrid seeds as per government guidelines in Nepal. Participating students were then able to practice detasseling and roughing off-type plants from a single row in a hybrid maize production field, under the guidance and supervision of the team from CIMMYT and the seed company.

This was followed by an interactive discussion with representatives from Lumbini about their activities, developments and limitations, and a tour of the company’s seed processing, laboratory and storage for the group to observe the techniques used to produce, maintain and market quality seeds.

A nourishing experience

Applying the theoretical learnings of plant breeding and agronomy courses in a practical setting was an eye-opener for the postgraduates.

Student Sadhana Poudyal shared how the event had boosted her confidence in performing critical activities such as identifying the key features of pollen and seed parents. Now majoring in Seed Science and Technology, Poudyal previously worked with the Nepal Agriculture Research Council (NARC) and was granted a scholarship by CIMMYT, through the NSAF project, to begin a postgraduate program in 2019. “I was fascinated to learn about the remarkable progress made in hybrid seed production and I feel motivated to work in this sector in the future,” she said. Poudyal plans to use these learnings during her research into baby corn at NARC after completing her studies.

“I have always been keen on learning plant genetics and breeding as I foresee a good scope in this area,” said Lokendra Singh, another student at AFU. “This trip was definitely insightful, and I thoroughly enjoyed receiving a practical lesson on the advantages and limitations of the various types of hybrids including single and three-way cross hybrids. Today’s experience has doubled my enthusiasm to work as a plant breeder after my graduation.”

It is critical to engage students on the recent advances in seed science so that they are encouraged to pursue a career in agricultural research in Nepal. “One of the major challenges is recruiting a workforce with critical skills and knowledge in the local seed industry since many students go abroad after they graduate,” said Upadhyaya. “We look forward to partnering with agricultural universities for many similar on-site learnings.”

Educational experiences in the field, such as this, provide a better picture of the recent advancements and limitations in the seed sector which are usually not reflected in the textbooks. Creating a larger pool of skillful human resources, particularly in hybrid product development, improved seed production technologies and quality seed production, will not only help strengthen the local seed industry but also reduce the country’s dependency on imports in the coming years.

AAA drought-tolerant maize now available in Myanmar

This month smallholder farmers in Myanmar’s central dry zones will be able to access drought-tolerant hybrid maize for the first time. The variety, known as TA5085, was jointly developed by the International Maize and Wheat Improvement Center (CIMMYT) and Syngenta, and has been commercially registered as ASC 108 by Ayeryarwady Seed in Myanmar. An initial, two-acre seed production pilot by Ayeyarwady Seed resulted in a yield of 1.2 tons per acre.

TA5085 was developed as an International Public Good as part of the decade-long Affordable, Accessible, Asian (“AAA”) Drought-Tolerant Maize project, a public-private partnership between CIMMYT and Syngenta and funded by the Syngenta Foundation. The project aims to make tropical maize hybrids accessible to Asian smallholders, especially those producing under rain-fed conditions in drought-prone areas.

“AAA maize is not just a product,” said B.S. Vivek, regional maize breeding coordinator and principal scientist at CIMMYT. “The development of affordable and accessible drought-tolerant maize hybrids helps drive the maize seed market in underserved maize markets in Asia.”

TA5084, the previous iteration of this variety, was first commercialized in central India, where climate change is driving rising temperatures and increasingly erratic rainfall. From 2018 to 2020, TA5084 adoption in the region grew from 900 to 8,000 farmers. In 2020, 120 metric tons of AAA-maize were planted on 6,000 hectares in central India. Farmers who switched to TA5084 earned an average of $100/ha more than those using conventional maize.

“Despite the unprecedented challenges we all faced in 2020, AAA hybrid maize sales more than doubled from the previous year, to 120 tons,” said Herve Thieblemont, head of Seeds2B Asia and Mekong Director at the Syngenta Foundation. “I’m delighted to report that the second country to introduce AAA maize is Myanmar. Our local seed partner Ayeyarwady Seed recently completed the registration and will proceed with the first sales this coming season.”

The AAA initiative is one of the few examples of a public-private partnership delivering International Public Goods benefiting smallholders in central India and now Myanmar. The chosen regions are rainfed and drought-prone. Seed marketing in these regions is considered risky and unpredictable, disincentivizing multinationals and large seed companies from entering the market.

Fighting the stress

East African Seed Company has a rich history of nearly 50 years, serving farmers with improved climate-resilient seed varieties. Established in 1972, the company produces and sells improved seed, through a wide distribution network in at least 15 countries in sub-Saharan Africa. It also markets agrochemicals and other farm inputs, and has ambitions of expanding to the rest of Africa, trading as Agriscope Africa Limited.

Smallholder farmers in sub-Saharan Africa continue to face multiple biotic and abiotic stresses as they try to improve their farms’ productivity and their livelihoods. Maize seed that guarantees high yield is a key trait, coupled with other key attributes such as drought tolerance, disease and pest resistance, early seedling vigor as well as suitability for food and animal feed.

With the varieties serving both small- and large-scale commercial farmers, challenges such as the fall armyworm, diminishing soil fertility and erratic rains have persisted in recent years and remain as key farming obstacles. “Such challenges diminish crop production and the grain quality thereby, lessening farmers’ profitability,” says Rogers Mugambi, Chief Operating Officer of East African Seed Company.

Scientists at the International Maize and Wheat Improvement Center (CIMMYT), in collaboration with partners in the national agriculture research systems and the commercial seed sector, continue to develop seed varieties that can guarantee decent yield even in times of climatic, disease and pest stress.

Top-notch research trickles down to farmers

Over the years, East African Seed has inked partnerships with CIMMYT, national research institutes and other agencies in the countries where it operates. Such partnerships have been the driving force to its success and the impacts within the farming communities in sub-Saharan Africa.

“Our collaboration with CIMMYT began in 2008 with germplasm acquisition. The cooperation has expanded to include testing networks for new hybrids, early-generation seed production and marketing. The overall beneficiary is the smallholder farmer who can access quality seeds and produce more with climate-smart products,” Mugambi says.

Apart from the multi-stress-tolerant varieties developed and released over time by the national agricultural research programs, CIMMYT recently announced a breakthrough: fall armyworm-tolerant elite maize hybrids for eastern and southern Africa. This success followed three years of rigorous research and experiments conducted in Kenya and signified a key milestone in the fight against fall armyworm.

As part of the partnership in the Drought Tolerant Maize for Africa (DTMA) and Stress Tolerant Maize for Africa (STMA) projects, East African Seed Company (Agriscope Africa Limited) established demonstration farms and conducted field days in Kenya, reaching thousands of farmers as a result. It was also able to produce early generation seed, which supported production of 2,000 metric tons of certified seed. This partnership now continues in the Accelerating Genetic Gains in Maize and Wheat (AGG) project.

The company has contracted large- and small-scale growers across the country to meet its seed production targets.

“Most of our small-scale growers are clustered in groups of up to 30 farmers with less than five acres of farmland. The large growers have advanced irrigation facilities such as the pivot system and seed processing plants. The seed from the fields is pre-cleaned and dried in the out-grower facilities before delivery to our factory for further cleaning and processing,” Mugambi explains.

Out with the drought

Currently, of the 1,300 metric tons of drought-tolerant hybrid seeds it produces yearly, 500 metric tons constitute those derived from the partnership in the STMA project. Two notable hybrids,  HODARI (MH501) and TOSHEKA (MH401), were derived during the DTMA and STMA projects. Released in 2014 and accepted for regional certification through the Common Market for Eastern and Southern Africa (COMESA)’s regional catalogue, the MH501 is a mid-altitude adapted and medium maturing three-way cross hybrid. The yield advantage of 15% over the local commercial checks triggered widespread adoption by the farmers, according to Mugambi. In Kenya, it was used as a commercial check during national performance trials, from 2017 to 2019.

The MH401, an early maturing hybrid with moderate drought tolerance, has been adopted in lowland and mid-altitude dry ecologies of Kenya and Tanzania. It has a 20% yield advantage over the local commercial checks.

As part of its varietal replacement, East African Seed Company looks to steadily retire older varieties such as KH600-15A and WE1101 and promote new ones including TAJIRI (EASH1220), TAJI (MH502) and FARAJA (MH503).

To promote new varieties and successfully reach smallholders, the company conducts field days, farm-level varietal demonstrations, road shows and radio programs. It also disseminates information on the benefits of new varieties while also dispensing promotional materials such as branded t-shirts and caps.

“Additionally, we organize annual field days at our research farm in Thika, where key and influential farmers and other stakeholders are invited from across Kenya and neighboring countries to learn about our new agricultural technologies,” Mugambi says.

Fast-tracked adoption of second-generation resistant maize varieties key to managing maize lethal necrosis in Africa

Scientists are calling for accelerated adoption of new hybrid maize varieties with resistance to maize lethal necrosis (MLN) disease in sub-Saharan Africa. In combination with recommended integrated pest management practices, adopting these new varieties is an important step towards safeguarding smallholder farmers against this devastating viral disease.

A new publication in Virus Research shows that these second-generation MLN-resistant hybrids developed by the International Maize and Wheat Improvement Center (CIMMYT) offer better yields and increased resilience against MLN and other stresses. The report warns that the disease remains a key threat to food security in eastern Africa and that, should containment efforts slacken, it could yet spread to new regions in sub-Saharan Africa.

The publication was co-authored by researchers at the International Maize and Wheat Improvement Center (CIMMYT), Kenya Agricultural and Livestock Research Organization (KALRO), the Alliance for a Green Revolution in Africa (AGRA), the African Agricultural Technology Foundation (AATF) and Aarhus University in Denmark.

Stemming the panic

The first reported outbreak of MLN in Bomet County, Kenya in 2011 threw the maize sector into a panic. The disease caused up to 100% yield loss. Nearly all elite commercial maize varieties on the market at the time were susceptible, whether under natural of artificial conditions. Since 2012, CIMMYT, in partnership with KALRO, national plant protection organizations and commercial seed companies, has led multi-stakeholder, multi-disciplinary efforts to curb MLN’s spread across sub-Saharan Africa. Other partners in this endeavor include the International Institute of Tropical Agriculture (IITA), non-government organizations such as AGRA and AATF, and advanced research institutions in the United States and Europe.

In 2013 CIMMYT established an MLN screening facility in Naivasha. Researchers developed an MLN-severity scale, ranging from 1 to 9, to compare varieties’ resistance or susceptibility to the disease. A score of 1 represents a highly resistant variety with no visible symptoms of the disease, while a score of 9 signifies extreme susceptibility. Trials at this facility demonstrated that some of CIMMYT’s pre-commercial hybrids exhibited moderate MLN-tolerance, with a score of 5 on the MLN-severity scale. CIMMYT then provided seed and detailed information to partners for evaluation under accelerated National Performance Trials (NPTs) for varietal release and commercialization in Kenya, Tanzania and Uganda.

Between 2013 and 2014, four CIMMYT-derived MLN-tolerant hybrid varieties were released by public and private sector partners in East Africa. With an average MLN severity score of 5-6, these varieties outperformed commercial MLN-sensitive hybrids, which averaged MLN severity scores above 7. Later, CIMMYT breeders developed second-generation MLN-resistant hybrids with MLN severity scores of 3–4. These second-generation hybrids were evaluated under national performance trials. This led to the release of several hybrids, especially in Kenya, over the course of a five-year period starting in 2013. They were earmarked for commercialization in East Africa beginning in 2020.

Widespread adoption critical

The last known outbreak of MLN was reported in 2014 in Ethiopia, marking an important break in the virus’s spread across the continent. Up to that point, the virus had affected the Democratic Republic of the Congo, Kenya, Rwanda, Tanzania and Uganda. However, much remains to be done to minimize the possibility of future outbreaks.

“Due to its complex and multi-faceted nature, effectively combating the incidence, spread and adverse effects of MLN in Africa requires vigorous and well-coordinated efforts by multiple institutions,” said B.M. Prasanna, primary author of the report and director of the Global Maize Program at CIMMYT and of the CGIAR Research Program on Maize (MAIZE). Prasanna also warns that most commercial maize varieties being cultivated in eastern Africa are still MLN-susceptible. They also serve as “reservoirs” for MLN-causing viruses, especially the maize chlorotic mottle virus (MCMV), which combines with other viruses from the Potyviridae family to cause MLN.

“This is why it is very important to adopt an integrated disease management approach, which encompasses extensive adoption of improved MLN-resistant maize varieties, especially second-generation, not just in MLN-prevalent countries but also in the non-endemic ones in sub-Saharan Africa,” Prasanna noted.

The report outlines other important prevention and control measures including: the production and exchange of “clean” commercial maize seed with no contamination by MLN-causing viruses; avoiding maize monocultures and continuous maize cropping; practicing maize crop rotation with compatible crops, especially legumes, which do not serve as hosts for MCMV; and continued MLN disease monitoring and surveillance.

Noteworthy wins

In addition to the development of MLN-resistant varieties, the fight against MLN has delivered important wins for both farmers and their families and for seed companies. In the early years of the outbreak, most local and regional seed companies did not understand the disease well enough to produce MLN-pathogen free seed. Since then, CIMMYT and its partners developed standard operating procedures and checklists for MLN pathogen-free seed production along the seed value chain. Today over 30 seed companies in Ethiopia, Kenya, Uganda, Rwanda and Tanzania are implementing these protocols on a voluntary basis.

“MLN represents a good example where a successful, large-scale surveillance system for an emerging transboundary disease has been developed as part of a rapid response mechanism led by a CGIAR center,” Prasanna said.

Yet, he noted, significant effort and resources are still required to keep the maize fields of endemic countries free of MLN-causing viruses. Sustaining these efforts is critical to the “food security, income and livelihoods of resource-poor smallholder farmers.

To keep up with the disease’s changing dynamics, CIMMYT and its partners are moving ahead with novel techniques to achieve MLN resistance more quickly and cheaply. Some of these innovative techniques include genomic selection, molecular markers, marker-assisted backcrossing, and gene editing. These techniques will be instrumental in developing elite hybrids equipped not only to resist MLN but also to tolerate rapidly changing climatic conditions.

The International Maize and Wheat Improvement Center (CIMMYT) is pleased to announce the successful development of three CIMMYT-derived fall armyworm-tolerant elite maize hybrids for eastern and southern Africa.

Fall armyworm (Spodoptera frugiperda) emerged as a serious threat to maize production in Africa in 2016 before spreading to Asia in 2018. Host plant resistance is an important component of integrated pest management (IPM). By leveraging tropical insect-resistant maize germplasm developed in Mexico, coupled with elite stress-resilient maize germplasm developed in sub-Saharan Africa, CIMMYT worked intensively over the past three years to identify and validate sources of native genetic resistance to fall armyworm in Africa. This included screening over 3,500 hybrids in 2018 and 2019.

Based on the results of on-station screenhouse trials for fall armyworm tolerance (under artificial infestation) conducted at Kiboko during 2017-2019, CIMMYT researchers evaluated in 2020 a set of eight test hybrids (four early-maturing and four intermediate-maturing) ) against four widely used commercial hybrids (two early- and two intermediate-maturing) as checks. The trials conducted were:

  • “No choice” trial under fall armyworm artificial infestation in screenhouses in Kiboko, Kenya: Each entry was planted in 40 rows in a separate screenhouse compartment (“no-choice”), and each plant infested with seven fall armyworm neonates 14 days after planting. Foliar damage was assessed 7, 14 and 21 days after infestation. Ear damage and percent ear damage were also recorded, in addition to grain yield and other agronomic parameters.
  • On-station trials in eastern Africa: The trials, including the eight test entries and four commercial checks, were conducted at six locations in Kenya during the maize cropping season in 2020. Entries were evaluated for their performance under managed drought stress, managed low nitrogen stress, and under artificial inoculation for Turcicum leaf blight (TLB) and Gray leaf spot (GLS) diseases. The three-way cross CIMMYT test hybrids and their parents were also characterized on-station for their seed producibility, including maximum flowering time difference between parents, and single-cross female parent seed yield.

The eight test entries with fall armyworm tolerance were also included in the regional on-station trials (comprising a total of 58 entries) evaluated at 28 locations in Kenya and Tanzania. The purpose of these regional trials was to collect data on agronomic performance.

  • On-farm trials in Kenya: The eight test hybrids and four commercial checks were evaluated under farmers’ management conditions (without any insecticide spray) at 16 on-farm sites in Kenya. Each entry was planted in 20-row plots, and data was recorded on natural fall armyworm infestation. Foliar damage was assessed 7, 14, 21, 28 and 35 days after germination together with insect incidence. Ear damage and percent ear damage were also recorded, besides grain yield and other agronomic parameters.

Note the difference in the harvest of a FAWTH hybrid (E) versus one of the commercial susceptible hybrid checks (F), besides the extent of damage caused by fall armyworm to the ears of the susceptible check (visible as blackish spots with no grains in the ears).

Summary of the data

  • “No-choice” trials in screenhouses at Kiboko: Significant differences were observed between the three selected fall armyworm tolerant hybrids (FAWTH2001-2003) and the commercial benchmark hybrid checks at the vegetative and grain filling stages and at harvest (Figure 1). In the fall armyworm artificial infestation trial, the three selected FAWTH hybrids yielded 7.05 to 8.59 t/ha while the commercial checks yielded 0.94-1.03 t/ha (Table 1).
  • On-station trials: No significant differences were observed between the three selected FAWTH hybrids and the commercial checks for grain yield and other important traits evaluated under optimum, managed drought stress, low nitrogen stress, TLB and GLS diseases (Table 1). The three FAWTH hybrids recorded excellent synchrony in terms of flowering between the female and male parents, and very good female parent seed yield (Table 1).
  • On-farm trials: There were significant differences in terms of foliar damage ratings between the FAWTH hybrids and the commercial checks. For ear damage, the differences were not statistically significant. The grain yields did not vary significantly under natural infestation in the on-farm trials because of the very low incidence of fall armyworm at most sites.

Native genetic resistance to fall armyworm in maize is partial, though quite significant in terms of yield protection under severe fall armyworm infestation, as compared to the susceptible commercial checks. Sustainable control of fall armyworm is best achieved when farmers use host plant resistance in combination with other components of integrated pest management, including good agronomic management, biological control and environmentally safer pesticides.

Next Steps

Together with national agricultural research system (NARS) partners, CIMMYT will nominate these FAWTH hybrids for varietal release in target countries in sub-Saharan Africa, especially in eastern and southern Africa.  After national performance trials (NPTs) and varietal release and registration, the hybrids will be sublicensed to seed company partners on a non-exclusive, royalty-free basis for accelerated seed scaling and deployment for the benefit of farming communities.

Delivering improved maize seed against all odds

As one of the pioneer homegrown seed companies in Uganda, Farm Inputs Care Centre (FICA) has become one of the leading players in the seed sector value chain. Since its inception in 1999, it has played a significant role in variety development and maintenance, seed production, and processing, packaging and marketing.

The close linkages it has maintained with partners such as National Agriculture Research Organization (NARO)’s National Crops Resources Research Institute (NaCCRI) and the International Maize and Wheat Improvement Center (CIMMYT) have seen it acquire new hybrids for commercialization and production of early generation seed.

A unique opportunity for collaboration

Recurrent plant threats such as drought, pests and diseases — alongside the perpetual need to develop and foster better performing varieties in changing climatic conditions — has required partners to intensify efforts to tackle these challenges to bolster smallholders’ resilience. The Drought Tolerant Maize for Africa (DTMA) project, for instance, ushered in the partnership between CIMMYT, FICA, national agriculture research systems, and other partners to develop and scale up well-adapted, drought-tolerant maize varieties among farmers in Uganda and elsewhere in sub-Saharan Africa.

“One of the unique features of the collaboration is that besides CIMMYT, there was a multi-stakeholder platform that would convene key seed sector players to discuss issues affecting the industry. Ultimately, this benefitted the farmers,” says FICA’s Chief Executive Officer Narcis Tumushabe.

This partnership continued during the Stress Tolerant Maize for Africa (STMA) initiative —  which ran from 2016 to2020 — and now, in the Accelerating Genetic Gains in Maize and Wheat (AGG) project, which launched in July 2020 with the ambition of fast-tracking the development of climate-resilient, higher-yielding, demand-driven, gender-responsive and nutritious maize and wheat varieties.

Tumushabe is happy that the hybrids delivered in the DTMA and STMA projects proved worthwhile against multiple stresses in farmers’ fields, offering reliable yields even in challenging conditions like drought or other stresses. Because of the diverse ecological zones in Uganda, it was essential to test the hybrids FICA accessed through the CIMMYT-NARO partnership across different ecological zones, ahead of commercialization. This has given farmers opportunities to choose the varieties that are suitable in their environment. The five varieties FICA chose to promote include Longe 9H — which produces about 700 metric tons annually — and WE 2114, WE 2115, WE 3106 and UH 5355, which cumulatively produce about 1,300 tons annually.

The WE 3106 variety has a strong stem and produces big cobs and Tumushabe notes that some livestock farmers prefer this variety as a good forage source for their livestock. Large-scale commercial farmers prefer WE 2114 due to the positioning of the ears at a uniform height, which makes it easy for harvesting using combine harvesters.

Additionally, FICA breeders have also developed impactful combination hybrids using CIMMYT and FICA lines and the company looks to double its annual production of certified stress-tolerant maize seed to 4,000 metric tons in the next five years. Currently, it enlists about 800 contract seed growers to support its seed multiplication efforts.

Surmounting monumental challenges for varietal turnover

Promoting new seed varieties, especially in a highly competitive market, is no mean task. With the seed delivery systems in sub-Saharan Africa mainly driven by the supply side, seed companies end up multiplying only the popular varieties that are already in high demand, explains Mosisa Worku Regasa, a seed systems specialist at CIMMYT.

“Consequently, these companies become reluctant to multiply new seed varieties due to deficient demand, thereby slowing down the rate of varietal turnover,” says Mosisa. “There is, however, a growing push for a demand-driven system.”

“Some avenues for cultivating a demand-led environment include investing a great deal of resources to better understand farmers’ preferences or product profiles, setting up numerous demonstration plots for newer, better-performing varieties closer to the farmers locations in addition to investing in other marketing and promotional activities.”

Still, the seed sector must confront other dynamics such as farmers that are captive of old albeit popular varieties.

“There are cases where, depending on the stage of a seed company’s development, the number of products that one can deliver in the right quality and appropriate maintenance level has to be limited or realistically managed,” Tumushabe explains.

“The seed company also ought to be sure that the new variety will be superior to existing varieties under farmers’ conditions. That is why one may find little excitement if the genetic gain of a new crop variety is not significantly high compared to the already known and available crop variety. This may make one wonder why an old variety continues to persist in the market.”

To create awareness and sustain the demand for its seed, FICA has established demonstration farms to showcase the performance of its stress-resilient maize varieties among farmers and engaged agro-dealers as last mile seed merchants. It is also during field days held at demonstration farms where the company obtains feedback on how to improve its breeding program, particularly from women smallholder farmers. Such efforts have helped raise the company’s share of stress-tolerant maize seed production to 70% of the total maize seed it produces, which indicates good progress in variety replacement.

Collaborating to accelerate genetic gains in maize and wheat

Stakeholders in the Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG) project have pledged to strengthen efforts to deliver desirable stress tolerant, nutritious and high-yielding maize and wheat varieties to smallholder farmers in a much shorter time. The alliance, comprising funders, national agricultural research systems (NARS), private seed companies, non-governmental organizations, the International Maize and Wheat Improvement Center (CIMMYT) and, for the maize component the International Institute for Tropical Agriculture (IITA), made these assurances during virtual events held in July and August 2020, marking the inception of the 5-year AGG project.

The initiative seeks to fast-track the development of higher-yielding, climate resilient, demand-driven, gender-responsive and nutritious seed varieties for maize and wheat, two of the world’s most important staple crops. The project is funded by the Bill & Melinda Gates Foundation, the Foreign, Commonwealth & Development Office (FCDO), the U.S. Agency for International Development (USAID), and the Foundation for Food and Agriculture Research (FFAR).

Tackling current and emerging threats

Jeff Rosichan, scientific program director of the Foundation for Food and Agricultural Research (FFAR),  acknowledged the significant and ambitious aim of the project in tackling the challenges facing maize and wheat currently and in the future. “We are seeing the emergence of new pests and pathogens and viral diseases like never before. A lot of the work of this project is going to help us to tackle such challenges and to be better prepared to tackle emerging threats,” he said.

AGG builds on gains made in previous initiatives including Drought Tolerant Maize for Africa (DTMA), Improved Maize for African Soils (IMAS), Water Efficient Maize for Africa (WEMA), Stress Tolerant Maize for Africa (STMA) and Delivering Genetic Gain in Wheat (DGGW), with support from partners in 17 target countries in sub-Saharan Africa (SSA) and South Asia.

Hailu Wordofa, agricultural technology specialist at the USAID Bureau for Resilience and Food Security, underscored his expectation for CIMMYT’s global breeding program to use optimal breeding approaches and develop strong collaborative relationships with NARS partners, “from the development of product profiles to breeding, field trials and line advancement.”

Similarly, Gary Atlin, senior program officer at the Bill & Melinda Gates Foundation lauded the move toward stronger partnerships and greater emphasis on the CIMMYT and IITA breeding programs. “The technical capacity of partners has increased through the years. It is prudent to ensure that national partnerships continue. It is always a challenging environment, this time multiplied by the COVID-19 crisis, but through this collaboration, there is a greater scope to strengthen such partnerships even more,” he said.

Symbiotic partnerships with great impact

“From the NARS perspective, we are committed to doing our part as primary partners to deliver the right seed to the farmers,” said Godfrey Asea, director of the National Crops Resources Research Institute at the National Agriculture Research Organization (NARO), Uganda. “We see an opportunity to review and to use a lot of previous historical data, both in-country and regionally and to continue making improved decisions. We also reiterate our commitment and support to continuously make improvement plans in our breeding programs.”

Martin Kropff, director general of CIMMYT, recognized the tremendous impact arising from the longstanding cooperation between CIMMYT’s maize and wheat programs and national programs in countries where CIMMYT works. “A wheat study in Ethiopia showed that 90% of all the wheat grown in the country is CIMMYT-related, while an impact study for the maize program shows that 50% of the maize varieties in Africa are CIMMYT-derived. We are very proud of that – not for ourselves but for the people that we work for, the hundreds of millions of poor people and smallholder farmers who really rely on wheat and maize for their living and for their incomes,” he said.

Founder and Chief Executive Officer of East Africa-based Western Seed Company Saleem Esmail expressed optimism at the opportunities the project offers to improve livelihoods of beneficiaries. “I believe we can do this by sharing experiences and by leveraging on the impacts that this project is going to bring, from new technologies to new science approaches, particularly those that help save costs of seed production.”

He, however, observed that while the target of fast-tracking varietal turnover was great, it was a tough call, too, “because farmers are very risk averse and to change their habits requires a great deal of effort.”

On his part, director of Crop Research at the Oromia Agricultural Research Institute (OARI) in Ethiopia Tesfaye Letta revealed that from collaborative research work undertaken with CIMMYT, the institute has had access to better-quality varieties especially for wheat (bread and durum). These have helped millions of farmers to improve their productivity even as Ethiopia aims for wheat self-sufficiency by expanding wheat production under irrigation.

“We expect more support, from identifying wheat germplasm suitable for irrigation, developing disease resistant varieties and multiplying a sufficient quantity of early generation seed, to applying appropriate agronomic practices for yield improvement and organizing exposure field visits for farmers and experts,” he said.

Challenges and opportunities in a time of crisis

Alan Tollervey, head of agriculture research at Foreign, Commonwealth and Development Office (FCDO) and the UK representative to the CGIAR System Council, emphasized the need for continued investment in agricultural research to build a resilient food system that can cope with the demands and pressures of the coming decades. This way, organizations such as CIMMYT and its partners can adequately deliver products that are relevant not only to the immediate demands of poor farmers in developing countries – and the global demand for food generally – but also to address foreseen threats.

“We are at a time of intense pressure on budgets, and that is when projects are most successful, most relevant to the objectives of any organization, and most able to demonstrate a track record of delivery. CIMMYT has a long track history of being able to respond to rapidly emerging threats,” he said.

Felister Makini, the deputy director general for crops at the Kenya Agricultural Research Organization (KALRO) lauded the fact that AGG not only brings together maize and wheat breeding and optimization tools and technologies, but also considers gender and socioeconomic insights, “which will be crucial to our envisioned strategy to achieve socioeconomic change.”

Zambia Agriculture Research Organization (ZARI) maize breeder Mwansa Kabamba noted that the inclusion of extension workers will help to get buy-in from farmers especially as far as helping with adoption of the improved varieties is concerned.

In its lifecycle, the AGG project aims to reduce the breeding cycles for both maize and wheat from 5-7 years currently to 3-4 years. By 2024, at least 150,000 metric tons of certified maize seed is expected to be produced, adopted by 10 million households, planted on 6 million hectares and benefit 64 million people. It also seeks to serve over 30 million households engaged in wheat farming the target countries.

As plant pests and diseases continue to evolve, with stresses like drought and heat intensifying, a major priority for breeders and partners is developing better stress tolerant and higher yielding varieties faster and more cost effectively.

A new project, Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG), seeks to achieve these results by speeding up genetic gains in maize and wheat breeding to deliver improved, stress resilient, nutritious seed to smallholders in 13 countries in sub-Saharan Africa (SSA) and four in South Asia. The 5-year AGG project is funded by the Bill & Melinda Gates Foundation, the UK Department for International Development (DFID), the U.S. Agency for International Development (USAID), and the Foundation for Food and Agriculture Research (FFAR).

The maize component of the project brings together diverse partners, including the International Maize and Wheat Improvement Center (CIMMYT) and the International Institute of Tropical Agriculture (IITA) as co-implementers; national agricultural research systems (NARS); and small and medium-sized (SME) seed companies.

Ambitious targets

At the inception meeting of the maize component of AGG on July 10, 2020, project leaders, partners and funders lauded the ambitious targets that aim to bolster the resilience and better the livelihoods, food and nutritional security of millions of smallholder farmers in SSA. At least 150,000 metric tons of certified seed is expected to be produced, adopted by 10 million households, planted on 6 million hectares by 2024 and benefiting 64 million people.

“We are developing climate resilient, nutritious, efficient, productive maize varieties for the farming community in sub-Saharan Africa. We will continue to work closely with our partners to develop product profiles, which are centered on the varieties that are really needed,” said CIMMYT Interim Deputy Director for Research Kevin Pixley.

AGG draws a solid foundation from previous projects such as Drought Tolerant Maize for Africa (DTMA), Improved Maize for Africa Soils (IMAS), Water Efficient Maize for Africa (WEMA) and Stress Tolerant Maize for Africa (STMA). Several high-yielding maize varieties that tolerate and/or resist diseases such as maize lethal necrosis (MLN), gray leaf spot (GLS), northern corn leaf blight, maize streak virus (MSV), turcicum leaf blight (TLB) and are drought-tolerant (DT), were developed and released to farmers across SSA. Varieties with nutritional traits such as nitrogen use efficiency (NUE) and quality protein maize (QPM) were also developed in the preceding initiatives.

A matter of “life or death”

“When farmers are confronted by aggressive farming challenges, they want products that address those challenges at the earliest opportunity. Waiting for years could mean the difference between life and death,” remarked David Chikoye, the director of Southern Africa Hub at IITA.

A key focus of AGG is to incorporate gender-intentionality – special attention to the needs of women farmers and consumers – from the traits bred into new varieties, through the communication and technology deployment strategies.

“AGG provides an excellent opportunity to reorient our maize breeding, seed scaling and delivery strategies for greater impact on the livelihoods of smallholder farmers, especially women and the disadvantaged communities that are not well reached so far,” said B.M. Prasanna, director of CIMMYT’s Global Maize Program and the CGIAR Research Program on Maize. “Our vision is to accelerate genetic gains to 1.5-2 percent annually across different breeding pipelines in the 13 participating countries in SSA and to reach over 10 million households with improved varieties.”

AGG will strengthen the capacity of partners to achieve and sustain accelerated variety replacement — or turnover — and increase genetic gains in farmers’ fields.

Old vs new

Many improved varieties have been released in the past decade. However, the turnover of old and obsolete varieties with new and improved ones is not happening as quickly as anticipated.

“We are producing good products and getting them out, but not at the speed that farmers need. How do we make it possible and profitable for seed companies to quickly introduce new hybrids?” posed Gary Atlin, program officer at the Bill & Melinda Gates Foundation. “We need to move towards a breeding and seed system where we know that we can develop a new product in 4 or 5 years and then get it to the farmers much more quickly. This is a complex problem.”

To enhance AGG’s ability to identify new products that perform well for farmers under their challenging circumstances, on-farm testing will be scaled up significantly.

Guest of honor, Ethiopia’s Minister of State for Agriculture Mandefro Nigussie, lauded CIMMYT’s support in improving the resilience and productivity of maize and wheat in the country. He observed that this has helped improve maize productivity in Ethiopia from around 2 tons/ha to about 4 tons/ha over the past two decades.

“We consider such a huge accomplishment as a combination of efforts in germplasm development and breeding efforts of CIMMYT and the Ethiopian national programs. That partnership will flourish further in this new project,” he said.

Reaching farmers in the last mile with seeds they can trust

Seed companies play a crucial role in delivering improved seed varieties to smallholder farmers. Masindi Seed Company Limited, located in Uganda’s mid-western region, is one such enterprise.

It traces its beginnings back to the Masindi District Farmers Association (MADFA) more than a decade ago. At the time, the association, which was comprised of about 9,000 farmers, was organized into a seed out-grower scheme of the then government-led Uganda Seed Project.

While its members were well trained, operated professionally and did their out-grower work diligently, the association faced one major challenge that almost broke it up: the ‘certified’ seed they bought from some seed firms could not germinate.

“At the time that we were operating solely as a farmers’ association, we did our best to grow maize seed for various seed companies who would then go on to produce and supply certified seed,” said Eugene Lusige, Masindi Seed general manager. “But we soon realized that a lot of the certified seed that we bought was of very poor quality due to their inability to germinate or because of low germination rates. This caused our farmers huge losses. We instead took this situation as a blessing in disguise, venturing into the certified seed production business based on our experience.”

Such turn of events meant the association had to not only produce the right seed, at the right price, at the right time and with the attributes their farmers desired, but also had to provide an opportunity to generate income for its members. By establishing Masindi Seed Company in 2009, the association members fulfilled their dream and ended up killing several birds with one stone by addressing multiple seed production challenges.

Over the past few decades, the liberalization of the Ugandan seed industry has seen it morph from government control, largely with the support of public sector research institutions, to increased private sector participation. This saw a resurgence in local and foreign-based seed firms involved in seed production, processing and marketing, which significantly contributed to increased delivery of certified seed to farming communities.

Reliable and beneficial partnerships

As one of the enterprises operating in the formal seed market, Masindi Seed has grown from strength to strength over the years, working closely with the National Crops Resources Research Institute (NaCRRI) of the National Agricultural Research Organization (NARO) in Uganda. The Longe 5D, an open pollinated variety (OPV) — an improved version of the Longe 5 — was the first certified seed that ushered them into the seed production and marketing landscape in 2009. The company accessed hybrids and parental materials from NARO, which works very closely with the International Maize and Wheat Improvement Center (CIMMYT) to obtain improved stress tolerant maize.

“Besides the parental materials we receive from CIMMYT through NARO, we are trained on best practices in quality seed production, and receive materials and financial support for some of our operations,” Lusige said.

In the first year, the company produced about 120-150 tons of the Longe 5D variety, which has remained their flagship product over the past decade. Currently, the variety has up to 65 % share of the company’s annual seed production capacity, which stands at about 1,200 tons. The annual capacity is poised to reach 2,400 by 2025 due to growing demand from farmers. The first stress tolerant hybrid, UH5053, was introduced in 2013 and two more hybrids have since gone into commercial production.

“The hybrids have much higher yield than the OPVs and other varieties in the market in this region. They are stress tolerant and some are early maturing,” Lusige said “But, the advantage with the Longe 5D is that it is much cheaper, with a seed packet going for less than its hybrid equivalent. So, it is best suited for the resource-constrained farmers who may not have the funds to buy artificial fertilizer. However, under normal farmer conditions, it yields between 1.5-1.8 tons per acre compared to a hybrid that can produce about 3 tons or more.”

The Longe 5D is also a quality protein maize (QPM) variety, which combats hidden hunger by providing essential amino acids that children and lactating mothers need, according to Godfrey Asea, director of the National Crops Resources Research Institute at NARO.

“One of the initiatives we have been working on is nutritious maize, with some of the OPVs that we have released in the past being QPM varieties,” Asea said. “We are thinking of integrating more nutrient qualities such as vitamin ‘A’ in new varieties, some of which are in the release pipeline. We have also acquired genetic resources that are rich in zinc. QPM varieties, as well as varieties that are biofortified with vitamin A and zinc are very important in improving household nutrition in the future for resource-constrained maize-dependent communities.”

To make farmers aware of available seed and important attributes, marketing and promotional activities through radio, flyers, banners, field days and on-farm demonstrations come in handy. For some newer varieties, the company goes as far as issuing small seed packs to farmers so they can see for themselves how the variety performs.

From a regional outfit to the national stage

In the beginning, growth was slow for Masindi Seed due to capacity and financial constraints to sustain promotional activities. Around 2013 and 2015, the company received support from the Alliance for a Green Revolution in Africa (AGRA) to scale-up its marketing and promotional efforts, which greatly enhanced Masindi Seed’s capacity and visibility. From then on, Masindi Seed went from being just a small regional-focused outfit to a nation-wide seed firm, marketing seed as far as northern and eastern Uganda.

By working closely with farmers, Masindi Seed Company puts itself at a strategic position to understand farmers’ preferred traits better. They have found that farmers prefer traits that allow them to earn more, such as higher yield, which allows them to harvest much more maize and sell the surplus for much-needed income.

Seed that farmers can trust

Alinda Sarah, who doubles up as both a contract farmer for Masindi Seed and a large-scale grower for maize grain, agrees that obtaining the right seed that is guaranteed to germinate and offers a higher yield is a major boost to her trade.

“All I require is seed that I trust to have the attributes I want. What works for me is the seed that offers a higher yield, and can tolerate common stresses including drought, diseases and pests. This way, I can sustain my farming business,” she says.

The second attribute the farmers keep mentioning to Masindi agricultural extensionists is the maturity period, with farmers inclined to prefer faster maturing varieties, such as varieties that mature in 90 days. Ultimately, beyond some of these desirable and beneficial traits, the farmer is, before anything else, interested in the germinability of the seed they buy.

“By confirming the attributes that we tell them regarding our varieties with what they see at demo farms, the farmers trust us more,” Lusige said. “Trust is good for a business like ours and we try our best to preserve it. In the past, we have seen how some companies who lost the trust of their customers quickly went out of business.”

“Besides offering improved seed to farmers, we encourage our partner seed companies to support and teach the farmers good agronomic practices such as proper fertilizer requirements and application rates, early planting, appropriate spacing, weed control, integrated pest management and intercropping with legumes,” said Daniel Bomet, maize breeder at NARO.

This little seed went to market

It’s not always easy to produce and sell new maize varieties in Malawi.

Seed companies often serve as the link between breeders and farmers, but numerous challenges — from lack of infrastructure to inconvenient finance systems — mean that the journey from the laboratory to the field is not always a smooth one.

In spite of this, the sector continues to grow, with established and up-and-coming seed companies all vying to carve their own niche in the country’s competitive maize seed market. To help bolster the industry, CIMMYT is working with around 15 seed companies in Malawi, providing them with early generation seed for CIMMYT-derived maize varieties, technical production training and marketing advice.

In a series of interviews, representatives from three of these companies share how they chose their flagship varieties and got them onto the market, and the CIMMYT support that helped them along the way.

Francis Maideni, Technical Breeder and Management Advisor at Demeter Seeds

The company started primarily because we wanted to help farmers — the issue of profits came later. The founders of Demeter Seeds saw a gap in the market for open-pollinated varieties (OPVs) and thought they could fill it. We’ve now migrated halfway into hybrids, but we still feel that we should serve both communities.

At the beginning we used to multiply and sell OPVs from CIMMYT, and we started doing our own multiplication here a few years ago. What I like about CIMMYT is they have been continuing to give us technical support. The breeding teams are our regular visitors. When they give us materials they come here, work with us, we go to the fields together. We’re so proud of this collaboration. Our whole company is based on CIMMYT germplasm since we don’t have our own breeding program to develop our own varieties.

How do you decide which varieties to work with?

When we were starting out, the decision of which varieties to work with was based on what CIMMYT recommended based on the data from on-farm trials. Most Malawian farmers use local maize varieties so it’s a good step for them to start using improved varieties – not necessarily hybrids.

Apart from the yields, what else do Malawian farmers look for? It has to be white and it has to be poundable or flint varieties with a hard endosperm. Of course, there are other attributes you have to worry about as well such as yield and drought tolerance. The seasons are changing, the rainfall period is becoming shorter so we’re looking for short-maturing materials in particular. If you have a variety that takes 90-100 days to mature, you’re OK, but if you choose one that takes 140-150, the farmer can be at risk of losing out because it doesn’t fit well into the growing season.

Having looked at those particular parameters we can decide on the variety we’re going to go for because this feeds into what our regular farmers want.

Is it easy to get farmers to buy those varieties, given that you know exactly what they’re looking for?

We’re not the only ones dealing with maize hybrids, so if you’re not aggressive enough in marketing you’ll not be able to survive.

You can’t just see that the demand is there and then put the product out. We have a marketing team within the company whose role is to market and advise the farmers. We try to listen to what’s happening on the ground, see how our varieties are performing and share results with the breeders. If you sell your seed you have to get feedback – whether it’s doing well or not.

But it can be difficult with the lack of infrastructure in Malawi. There are some places which are not accessible, so there are farmers who want your seed but you can’t reach them. Those farmers end up planting some local seed, which they might not have planted if they had access to improved varieties.

CIMMYT equals maize, so there’s very little we’d be doing without them. There has been collaboration and partnership since we started the seed business.

We got all the parent materials, expertise and production training from CIMMYT. We now even have our own CIMMYT-trained internal inspectors, who ensure that the seed that we produce meet quality standards that are required. When they were giving us the lines, they also helped us with production of the basic seed to start our maize production. Without CIMMYT, we wouldn’t be here.

You’re one of the few seed companies in Malawi producing vitamin A biofortified maize, which CIMMYT develops in partnership with HarvestPlus. How did you decide to work on that variety?

We selected the orange vitamin A maize firstly because of corporate social responsibility reasons. There is a developmental aspect to what we do, and we’re not just here for money. I think whatever we’re doing should also help the people that are buying from us. We knew that micronutrient deficiency is an issue in Malawi, so we hoped that the vitamin A biofortified maize could address some of the country’s malnutrition problems.

When the Government said it was looking at alternative ways of combating malnutrition, this was one of the proposed solutions and we thought we should be the first to do it. As of now, I think that of the 20-something lead seed businesses in Malawi, we’re one of only three producing this maize.

How challenging has it been to promote that variety?

Very, because the orange maize was not popular to begin with. In the first year, we had about 25 metric tons of seed and we didn’t even sell 10.

Yellow maize was brought in to feed people during a famine in the early 90s, so I think when people see orange maize now they are reminded of that hunger. There are still those negative associations. So we had to do some convincing, visiting farmers with HarvestPlus and telling them about the benefits.

But this is our third year and we don’t have any seed left — it’s all gone. Combined, the three companies involved in orange maize production had about 65 metric tons. But this year the demand has been around 1,050 metric tons. What we produced is not even one tenth of what is required.

Now that the orange maize has been popularized, we see demand increasing in the next five years as well. Apart from farmers, we’ve also had inquiries from people that want to use it for industrial purposes and are looking for very large quantities. Now we know, if people are looking for orange maize, we’ll be among the first to provide it.

I studied agribusiness management for my first degree and went into farming immediately after. Later I completed a Masters in Agronomy, but the moment I started talking to CIMMYT I knew that I was lacking knowledge on the technical side. Over the years I’ve attended a number of courses — maize technician courses and programs to help people in the seed industry learn about hybrids — thanks to CIMMYT. A large part of my knowledge has come from those trainings, visiting the research station in Harare and attending field days.

Global Seeds is known for its flagship product, MH34. Why did you decide to focus on that specific variety?

One of the main driving factors for us to go for MH34 was that it was not being produced by anyone else. This was a new variety that no other company had branded as their own yet, so it was a good opportunity for us to own it.

At the same time, I liked this variety because it had two lines from CIMMYT and one line that’s bred locally. It’s kind of a mix. I really liked that because it meant that it would be a bit of a challenge for anyone outside the country to produce it because they would not get that extra 25% from the Malawian line.

Did that also make it difficult for Global Seeds to produce?

It was not easy for us to get it on the market. It’s one of the stories I’m most proud of — to say we’re one of the few companies producing this variety — especially when I look back at the last three years and the work it took to get it to where we are.

We got the lines we needed from CIMMYT, but when we went to the local program to get that one last ingredient, we got less than 1.4 kilograms. Normally we would need at least 5 kilograms.

We knew we had to produce quickly to commercialize the variety, so we took 900 grams and started trying to increase the line under irrigation. Then the water supply ran out and we had to hire a water bowser. It was quite a journey but in the end we produced a handful of seed, and now the story is that this variety is flying off the shelves.

Seeing is believing

Nancy Wawira strolls through a small plot of maize at Kithimu, in Kenya’s Embu County. She is charmed by the attributes of a maize variety that can yield 2,700kg per acre or more. The variety can endure drought-like conditions, matures in less than 120 days and has potential for double-cobbing.

Wawira is visiting a demonstration farm to witness the performance of several high yielding, early to medium maturing, drought-tolerant maize varieties.

By coming to this demonstration farm, Wawira hoped to identify a newer maize variety she could plant on her quarter-acre of land to get higher yield. The plot she stood on was the exact replica of what she was looking for. “Occasions such as this field day are very important for me and I always endeavor to attend them, as there is always something new to see or learn,” she says.

On her farm, she has been planting one of the old but popular commercial varieties suitable for this mid-altitude ecology. She normally harvests 4 bags of maize, of 90kg each, every season. However, if there is not enough rain or if there are pests or diseases, which is often the case, she harvests just 2 bags or less. This is hardly enough to meet her family’s food requirements for the year.

Switching to the maize variety she was interested in, and applying recommended farming practices, she could harvest 6 bags per season or more.

“Today, I have learnt how to improve my farming,” says Wawira. “Even when I access the variety that is high yielding, drought-tolerant and can mature in about three and a half months, as I witnessed on one of the plots, I still need to pay attention to proper crop husbandry related to spacing, timing of the planting, seed, fertilizer and pesticide application besides weed control,” she says.

Made-to-order

Wawira was one of the more than 400 farmers from nearby Manyatta sub-county visiting the demonstration farm on February 7, 2020. They were able to see varieties and learn about their traits, invited by the Seed Trade Association of Kenya (STAK) with the support of the International Maize and Wheat Improvement Center (CIMMYT).

The demonstration is a continuation of the work started under the Drought Tolerant Maize for Africa Seed Scaling (DTMASS) project and later under the Stress Tolerant Maize for Africa (STMA) project.

Officials from Embu County, led by its minister in charge of agriculture Jamleck Muturi, were present during the farmers’ visit. Ten seed firms, some of which use CIMMYT’s germplasm for seed propagation and marketing, participated as well.

“Several of our member seed companies are showcasing the varieties developed through CIMMYT’s breeding pipeline,” said Duncan Ochieng’, the chief executive officer of STAK. “The maize varieties showcased on these demo farms were designed to be drought-tolerant, high yielding and range from early to medium maturing. These varieties are juxta-posted with other commercial varieties suitable for this region.”

During visits to demonstration farms, farmers give feedback on their variety preferences. Seed companies can then align their breeding, germplasm-access requests, seed production or marketing plans with farmers’ expectations.

Dire traits

Farming stresses such as pests, diseases, heat and drought have made targeted breeding a critical necessity.

Young farmers are increasingly choosing varieties that can mature faster, typically in less than three months. They also favor varieties that offer higher yield than the popular commercial varieties, many of which have been on the market for at least a decade. Other sought-after traits are good performance in low or erratic rains, tolerance to maize lethal necrosis, reduced lodging, and efficiency in nitrogen use.

Jackline Wanja, 25, relies on her one-acre farm for survival. “On average, I harvest about 25 bags per acre. On the demo farm, I got to know of a variety than can yield at least 30 bags per acre. I also learnt that the variety is not only drought-resilient but can also mature in about three and a half months. This is the variety that I plan to plant my farm next season,” Wanja said.

For John Njiru, 52, a higher-yielding variety with a lot of foliage, which remains green even after the maize cob has dried, is what he came looking for. For this farmer with 12 acres of land, the green maize foliage is a significant source of income when sold to livestock keepers. Njiru feeds his own livestock with it, making substantial savings on animal feed expenditure. “If this variety is as high yielding as I have been made to understand and can offer me at least 30 bags per acre, I would be a happy farmer. My farming would be very profitable,” he says.

A major step toward seed self-sufficiency

In an historical first, during the 2018-19 season Nepal’s National Maize Research Program (NMRP) coordinated the production of 4 tons of seed of a leading maize hybrid, as part of national efforts to boost maize production and meet rising demand for the crop.

NMRP oversaw production of Rampur Hybrid-10 seed, in collaboration with the Heat Tolerant Maize for Asia (HTMA) project funded by the USAID Feed the Future Initiative and led by the International Maize and Wheat Improvement Center (CIMMYT), the Nepal Seed and Fertilizer (NSAF) project, and local seed companies and farmer cooperatives.

“Producing hybrid maize seed and getting quality seed to farmers at a reasonable price involves multiple stakeholders,” said P.H. Zaidi, CIMMYT maize physiologist and HTMA leader. “NMRP is pursuing a public-private partnership model to have key value chain components in place for this. The success this year may encourage other companies to switch from producing seed of open-pollinated maize varieties to that of hybrids, which are higher yielding.”

Lumbini Seed Company alone harvested 2.5 tons of hybrid seed from one hectare of land, helping to debunk the common myth that production of maize hybrid seed was impossible in Nepal, according to Zaidi.

“Lumbini did good groundwork to identify a suitable season and site for seed production, helping them to achieve a good hybrid seed harvest in their first-ever attempt,” said Zaidi. “The NMRP and other seed companies contributed valuable knowledge and advice to improve and scale up hybrid maize seed production.”

Maize is a critical food, feed and fodder crop in Nepal, providing nearly 20% of people’s food energy and accounting for around 33% of all cereal production in the high hills regions, 39% in the mid-hills region, and 9% in the Terai. Over two-thirds of hill-region maize is eaten directly as food on farm homesteads, whereas 80% of maize in the Terai and neighboring regions is used as feed.

Demand for feed maize is skyrocketing, as consumers switch from starch-based foods to animal protein and dairy products. Current national maize production satisfies less than a third of feed industry demand, requiring maize grain imports that reached 4.8 million tons in 2017-18.

Against this backdrop, many smallholder farmers still grow local or open-pollinated maize varieties, which are usually low yielding.

Based in Rampur, Chitwan, and established in 1972, the NMRP has developed and released 29 open-pollinated and 5 hybrid maize varieties, including Rampur Hybrid-10, with technical support from CIMMYT. Multinational companies have registered 54 other maize hybrids for marketing in Nepal. To date, nearly all hybrid seed is imported.

Other partners in efforts to produce hybrid seed in Nepal include the farmer cooperatives Namuna Sahakari and Jhapa, as well as the companies SEAN Seed in Kathmandu and Unique Seed Company in Dhangadi. NMRP is also developing and registering new high-yielding hybrids. Some nucleus and breeders seed is being produced by the Agricultural Research Station (ARS) and Regional Agricultural Research Station (RARS) of the Nepal Agricultural Research Council (NARC).

The NMRP and participating seed companies expect to meet half of Nepal’s hybrid maize seed requirements through such domestic seed production within five years, with the objective to achieve complete seed self-sufficiency later on.

Stress-resilient maize, a big relief for Indian farmers

Small-scale maize farmers beset by erratic rainfall in the state of Karnataka, India, who adopted a new, drought- and heat-tolerant maize hybrid are harvesting nearly 1 ton more of grain per hectare than neighboring farmers who sow other maize varieties.

The climate-resilient hybrid RCRMH2 was developed in 2015 by the University of Agriculture Sciences, Raichur (UAS-R), Karnataka, as part of the Heat Tolerant Maize for Asia (HTMA) project. It was marketed in 2018 under the commercial name MRM4070 by Maharashtra Hybrid Seeds Company (Mahyco) in hot and dry areas of Karnataka, where crops are watered exclusively by rainfall.

“This hybrid is made for our stress-prone areas, as it gives guaranteed yields in a bad year and is inferior to none under good rainfall conditions,” said Hanumanthappa, a farmer and adopter of the variety in Gadag District. “In bad years, it can not only feed my family but also my cattle,” he added, referring to the hybrid’s “stay-green” trait, which allows use of the leaves and stems as green fodder for livestock, after harvesting the cobs.

Droughts and high temperatures are a recurring problem in Karnataka, but suitable maize varieties to protect yields and income loss in the state’s risk-prone agroecologies had been lacking.

Mahyco marketed some 60 tons of hybrid seed of MRM4070 in Karnataka in 2018 and, encouraged by the overwhelming response from farmers, increased the seed offering to 140 tons — enough to sow about 7,000 hectares.

A 2018-19 farmer survey in the contrasting Gadag District — with poor rainfall — and Dharwad District — good rainfall — found that farmers in Gadag who grew MRM4070 harvested 0.96 tons more grain and earned $190 additional income per hectare than neighbors who did not adopt the hybrid. In Dharwad under optimal rainfall, MRM4070 performed on a par with other commercial hybrids.

In addition to providing superior yields under stress, MRM4070 had larger kernels than other hybrids under drought conditions, bringing a better price for farmers who sell their grain.

Led by the International Maize and Wheat Improvement Center (CIMMYT), in collaboration with national maize programs, agriculture universities, and seed companies, and with funding from the United State Agency for International Development (USAID) Feed the Future Initiative, HTMA was launched in 2012 to develop stress-resilient maize hybrids for the variable weather conditions and heat and drought extremes of Bangladesh, India, Nepal and Pakistan.
