Delivering improved maize seed against all odds

Written by Emma Orchardson on . Posted in News.

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.

New research by an international team of scientists, including scientists from the International Maize and Wheat Improvement Center (CIMMYT) and the Indian Council of Agricultural Research (ICAR), shows that adopting a portfolio of conservation agriculture and crop diversification practices is more profitable and better for the environment than conventional agriculture.

Reported last month in Nature Scientific Reports, the results of the study should encourage farmers and policymakers in South Asia to adopt more sustainable crop management solutions such as diversifying crop rotations, direct-seeding rice, zero tillage and crop residue retention.

Rice-wheat has for a long time been the dominant cropping system in the western Indo-Gangetic plains in India. However, issues such as water depletion, soil degradation and environmental quality as well as profitability have plagued farmers, scientists and decision makers for decades. To tackle these issues, researchers and policymakers have been exploring alternative solutions such as diversifying rice with alternative crops like maize.

“Climate change and natural resource degradation are serious threats to smallholder farmers in South Asia that require evidence-based sustainable solutions. ICAR have been working closely with CIMMYT and partners to tackle these threats,” said SK Chaudhari, deputy director general of the Natural Resource Management at ICAR.

In the study, CIMMYT scientists partnered with the ICAR-Central Soil Salinity Research Institute, International Rice Research Institute (IRRI), Borlaug Institute for South Asia (BISA), Swami Keshwan Rajasthan Agriculture University and Cornell University to evaluate seven cropping system management scenarios.

The researchers measured a business-as-usual approach, and six alternative conservation agriculture and crop diversification approaches, across a variety of indicators including profitability, water use and global warming potential.

They found that conservation agriculture-based approaches outperformed conventional farming approaches on a variety of indicators. For example, conservation agriculture-based rice management was found to increase profitability by 12%, while decreasing water use by 19% and global warming potential by 28%. Substituting rice with conservation agriculture-based maize led to improvements in profitability of 16% and dramatic reductions in water use and global warming potential of 84% and 95%. Adding the fast-growing legume mung bean to maize-wheat rotations also increased productivity by 11%, profitability by 25%, and significantly decreased water use by 64% and global warming potential by 106%.

However, CIMMYT Principal Scientist and study co-author M.L. Jat cautioned against the allure of chasing one silver bullet, advising policymakers in South Asia to take a holistic, systems perspective to crop management.

“We know that there are issues relating to water and sustainability, but at the same time we also know that diversifying rice — which is a more stable crop — with other crops is not easy as long as you look at it in isolation,” he explained. “Diversifying crops requires a portfolio of practices, which brings together sustainability, viability and profits.”

With South Asia known as a global “hotspot” for climate vulnerability, and the region’s population expected to rise to 2.4 billion by 2050, food producers are under pressure to produce more while minimizing greenhouse gas emissions and damage to the environment and other natural resources.

“Tackling these challenges requires strong collaborative efforts from researchers, policymakers, development partners and farmers,” said Andrew McDonald, a systems agronomist at Cornell University and co-author of the study. “This study shows this collaboration in action and brings us closer to achieving resilient, nutritious and sustainable food systems.”

“The results of this study show that one-size doesn’t fit all when it comes to sustainable crop management,” said PC Sharma, director of India’s ICAR-Central Soil Salinity Research Institute (ICAR-CSSRI). “Farmers, researchers and policymakers can adopt alternative crop rotations such as maize-wheat or maize-wheat-mung bean, but they can also improve existing rice-wheat rotations using conservation agriculture methods.”

With almost all CGIAR centers represented in Addis Ababa, Ethiopia is considered to be a hub for CGIAR research, and the organization has been a long-term partner to the Ethiopian government when it comes to agriculture. The partnership between CGIAR and the national partners is said to be an exemplary one, with CGIAR serving as the source of new technologies and innovations and national partners contextualizing these products within their own country context. This is believed to have brought impacts that serve the people on the ground.

A new report by CGIAR’s Standing Panel on Impact Assessment (SPIA) indicates that CGIAR innovations have reached between 4.1 and 11 million Ethiopian households. The report — which assesses 52 agricultural innovations and 26 claims of policy influence — documents the reach of CGIAR-related agricultural innovations across the core domains of CGIAR research activity: animal agriculture; crop germplasm improvement; natural resource management; and policy research.

The study compiles comprehensive information on the past two decades of CGIAR research activities in Ethiopia. Using information from interviews with CGIAR research leaders, scientists, government officials, published studies and project documents, this ‘stocktaking’ exercise was used to identify the innovations which are potentially disseminated at scale. The study also employs novel data collection protocols and methods like visual aid protocols for identification of natural resource management innovations or DNA fingerprinting for crop variety identification for barley, maize and sorghum.

The study results show that although many innovations are being adopted by some farmers, only a few are reaching large numbers of households. The three innovations with the largest reach are soil and water conservation practices, improved maize varieties and crossbred poultry. The study also found out that there are synergies between innovations where households adopt two or more. For instance, a household which adopts CGIAR maize varieties is likely to also adopt recommended natural resource management practices.

This, according to the study, is the result of different categories of CGIAR research efforts — natural resource management and policy, crop breeding and livestock research, respectively. The scaling of these innovations can also be linked to supportive government policies, which in turn have been influenced by policy research, as indicated in the report.

CIMMYT’s footprint

The International Maize and Wheat Improvement Center (CIMMYT) has maintained a presence in Ethiopia for over 30 years and is committed to supporting long-term agricultural development in the country. As part of this effort, CIMMYT has contributed to an increase in maize and wheat production in Ethiopia, working with national partners to test and release improved varieties.

The maize breeding program started in 1988 through CIMMYT and EIAR collaboration and in 1993 BH-660 was released — the first hybrid maize variety derived from CIMMYT germplasm. According to the report, specific maize traits were researched through the Drought Tolerant Maize for Africa (DTMA) and Drought Tolerant Maize for Africa Seed Scaling (DTMASS) projects, and since 2012 the Nutritious Maize for Ethiopia (NuME) project has aimed to develop varieties with higher protein content. Overall, 54 maize varieties have been released in Ethiopia since 1990, and 34 of these are thought to contain CIMMYT-related germplasm. It is also noted that, in the past 20 years ten drought-tolerant varieties and eight quality protein maize (QPM) varieties have been released.

In terms of geographical spread, the study highlights that improved maize varieties derived from CGIAR germplasm were highly adopted in the regions of Harar and Dire Dawa, which account for 81% of adopters overall. Adoption rates were also high in Tigray (79.3% of households), Amhara and the Southern Nations, Nationalities, and Peoples’ Region (63% of households), and Oromia (58.4% of households).

The other important crop in Ethiopia is wheat, which is grown by up to 4.8 million farmers in the country, according to the 2019 Central Statistics Authority (CSA) report. The SPIA document indicates that CGIAR innovations have played great role in the release and uptake of improved wheat varieties. The work of the CGIAR Research Program on Wheat (WHEAT), for instance, has resulted in the release of eight rust-resistant varieties derived from CIMMYT germplasm that are still under production. Of the 133 varieties released since 1974, CIMMYT and the International Center for Agricultural Research in the Dry Areas (ICARDA) played a role in developing at least 80.

The report concludes that agricultural research carried out by CGIAR scientists and their national partners generates many new ideas for innovations that might help address pressing policy concerns. CGIAR’s contribution to Ethiopia’s agricultural development is complex and wide-ranging, and while some aspects cannot be accurately captured by survey data, this new source of adoption and diffusion data helps identify the scale and scope of CGIAR’s reach in Ethiopia.

Improved metrics for better decisions

Written by Emma Orchardson on . Posted in News.

By adopting best practices and established modern tools, national agricultural research systems (NARS) are making data-driven decisions to boost genetic improvement. And they are measuring this progress through tracking and setting goals around “genetic gain.”

Genetic gain means improving seed varieties so that they have a better combination of genes that contribute to desired traits such as higher yields, drought resistance or improved nutrition. Or, more technically, genetic gain measures, “the expected or realized change in average breeding value of a population over at least one cycle of selection for a particular trait of index of traits,” according to the CGIAR Excellence in Breeding (EiB)’s breeding process assessment manual.

CGIAR breeders and their national partners are committed to increasing this rate of improvement to at least 1.5% per year. So, it has become a vital and universal high-level key performance indicator (KPI) for breeding programs.

“We are moving towards a more data-driven culture where decisions are not taken any more based on gut feeling,” EiB’s Eduardo Covarrubias told nearly 200 NARS breeders in a recent webinar on Enhancing and Measuring Genetic Gain. “Decisions that can affect the sustainability and the development of organization need to be based on facts and data.”

Improved metrics. Better decisions. More and better food. But how are NARS positioned to better measure and boost the metric?

EiB researchers have been working with both CGIAR breeding programs and NARS to broaden the understanding of genetic gain and to supply partners with methods and tools to measure it.

The recent webinar, co-sponsored by EiB and the CIMMYT-led Accelerating Genetic Gains in Maize and Wheat (AGG) project, highlighted tools and services that NARS are accessing, such as genotyping, data analysis and mechanization.

Through program assessments, customized expert advice, training and provision of services and resources, EiB researchers are helping national partners arrive at the best processes for driving and measuring genetic gains in their programs.

For example, the EiB team, through Crops to End Hunger (CtEH), is providing guidelines to breeders to help them maximize the accuracy and precision, while reducing the cost of calculating genetic gains. The guidelines make recommendations such as better design of trials and implementing an appropriate check strategy that permits regular and accurate calculation of genetic gain.

A comprehensive example at the project level is EiB’s High-Impact Rice Breeding in East and West Africa (Hi-Rice), which is supporting the modernization of national rice programs in eight key rice-producing countries in Africa. Hi-Rice delivers training and support to modernize programs through tools such as the use of formalized, validated product profiles to better define market needs, genotyping tools for quality control, and digitizing experiment data to better track and improve breeding results. This is helping partners replace old varieties of rice with new ones that have higher yields and protect against elements that attack rice production, such as drought and disease. Over the coming years, EiB researchers expect to see significant improvements in genetic gain from the eight NARS program partners.

And in the domain of wheat and maize, AGG is working in 13 target countries to help breeders adopt best practices and technologies to boost genetic gain. Here, the EiB team is contributing its expertise in helping programs develop their improvement plans — to map out where, when and how programs will invest in making changes.

NARS and CGIAR breeding programs also have access to tools and expertise on adopting a continuous improvement process — one that leads to cultural change and buy-in from leadership so that programs can identify problems and solve them as they come up. Nearly 150 national breeding partners attended another EiB/AGG webinar highlighting continuous improvement key concepts and case studies.

National programs are starting to see the results of these partnerships. The Kenya Agricultural & Livestock Research Organization (KALRO)’s highland maize breeding program has undertaken significant changes to its pipelines. KALRO carried out its first-ever full program costing, and based on this are modifying their pipeline to expand early stage testing. They are also switching to a double haploid breeding scheme with support from the CGIAR Research Program on Maize (MAIZE), in addition to ring fencing their elite germplasm for future crosses.

KALRO has also adopted EiB-supported data management tools, and are working with the team to calculate past rates of genetic gains for their previous 20 years of breeding. These actions — and the resulting data — will help them decide on which tools and methods to adopt in order to improve the rate of genetic gain for highland maize.

“By analyzing historical genetic gain over the last 20 years, it would be interesting to determine if we are still making gains or have reached a plateau,” said KALRO’s Dickson LIgeyo, who presented a Story of Excellence at EiB’s Virtual Meeting 2020. “The assessment will help us select the right breeding methods and tools to improve the program.”

Other NARS programs are on a similar path to effectively measure and increase genetic gain. In Ghana, the rice breeding program at Council for Scientific and Industrial Research (CSIR) have developed product profiles, identified their target market segments, costed out their program, digitized their operations, and have even deployed molecular markers for selection.

With this increased expertise and access to tools and services, national breeding programs are set to make great strides on achieving genetic gain goals.

“NARS in Africa and beyond have been aggressively adopting new ideas and tools,” says EiB’s NARS engagement lead Bish Das. “It will pay a lot of dividends, first through the development of state-of-the-art, and ultimately through improving genetic gains in farmers’ fields. And that’s what it’s all about.”

The cereals imperative of future food systems

The 2019 EAT-Lancet Commission report defines specific actions to achieve a “planetary health diet” enhancing human nutrition and keeping resource use of food systems within planetary boundaries. With major cereals still supplying about one-third of calories required in the proposed diet, the way they are produced, processed, and consumed must be a central focus of global efforts to transform food systems. This article from our annual report argues three main reasons for this imperative.

Battling devastating viral diseases, also in plants

Maize lethal necrosis (MLN) has taught us that intensive efforts to keep human and plant diseases at bay need to continue beyond the COVID-19 crisis. We interviewed B.M. Prasanna, director of the Global Maize Program at CIMMYT and the CGIAR Research Program on Maize (MAIZE), to discuss the MLN success story, the global COVID-19 crisis, and the similarities in the challenge to tackle plant and human viral diseases.

We had a similar conversation with Hans Braun, Director of the Global Wheat Program and the CGIAR Research Program on Wheat, who taled to us about the need for increased investment in crop disease research as the world risks a food security crisis related to COVID-19.

Taken together, digital monitoring and readily available data on the status of groundwater resources provide a critical foundation for sustainable irrigation development. While much is known about surface water resources and hydrological and meteorological linkages between the Terai, Mid-Hills and Himalaya regions of the country, Nepal currently lacks a comprehensive system for groundwater resource monitoring.

To respond to this crucial information gap, the International Maize and Wheat Improvement Center (CIMMYT) and International Water Management Institute (IWMI) are partnering with the Government of Nepal’s Groundwater Resources Development Board to conduct a pilot which will develop and test a potential groundwater monitoring system with the goal of identifying an approach which can be gradually scaled out after project completion.

To this end, the project team organized an Inception and Consultation Workshop, which took place virtually on October 14, 2020. This was the first in a series under the Cereal Systems Initiative for South Asia (CSISA) Nepal COVID-19 and Resilience project, funded by the United States Agency for International Development (USAID) Nepal, which supports farmers and rural economies in their response to COVID-19 and addresses, among others, various issues and ways forward for sustainable irrigation development.

The session aimed to introduce the digital groundwater monitoring pilot to local stakeholders, identify monitoring objectives and information needs, facilitate multi-stakeholder and inter-ministerial dialogue, and generate feedback and endorsement of the project plan. Participants were from a wide range of backgrounds and disciplines, and included members of local and national authorities, research centers and universities.

Madhukar Rajbhandari, director general of the Government of Nepal’s Department of Water Resources and Irrigation, opened the event and during his address highlighted the importance of groundwater irrigation for Nepal’s farming systems and livelihoods. He also captured the challenges which the country faces when developing groundwater irrigation, from polluted water resources through urbanization to lack of market access and the high maintenance costs of irrigation infrastructure. Rajbhandari noted that “agricultural and irrigation projects lack coordination” and expressed his hope that “through this pilot, the way is paved for a collaborative approach to develop practical groundwater solutions for farmers.”

The session introduced participants to the project and its background, leading breakout sessions for two groups: the first containing local, state and national government representatives; the second comprising farmers, researchers and members of industry. Each group was asked to identify the groundwater monitoring objectives and information needs that they would have as different types of users, and to provide feedback and recommendations to improve the project work plan.

The feedback showed that while government representatives are largely interested in developing a better understanding of the groundwater development potential, researchers and farmers are more concerned with possible discharge and water quality. Monitoring frequency was also identified as useful for daily to monthly timescales.

The group discussion revealed participants’ keen interest in consolidating and monitoring groundwater information, which highlights the importance of stakeholder engagement when developing pilots such as these, to ensure that when scaling is achieved, it caters to specific needs. Participants also expressed a strong interest in bringing the results of the project within the ambit of national policy, which would achieve the streamlining of data collection protocols for standardized, publicly accessible, data collection mechanisms.

“It is very encouraging to see such active participation and engagement from all the participants throughout the workshop,” noted Timothy Krupnik, project leader and a senior scientist at CIMMYT. “We look forward to maintaining this momentum, to support Nepal’s efforts in strengthening its capacity for sustainable irrigation.”

There is a growing crisis beneath our feet. Scientists, soil specialists and policy-makers around the world are sounding the alarm about degrading soil conditions. And it is particularly stark in developing countries. In fact, about 40 per cent of soils in sub-Saharan Africa are already of poor quality.

Declining soil health causes poor crop yields, leading to further pressure on the soils as farmers struggle to meet food demands and eke out a living. Many farmers lack access to information or technologies to get out of this vicious cycle. If you are a farmer with the need to increase your yield in the face of these challenges, crop breeding and soil management offers a range of solutions as part of an Integrated Soil Fertility Management (ISFM) approach.

For instance, breeding programs which partner with CGIAR Excellence in Breeding (EiB) are working to deliver the best seed varieties for farmers to help them withstand harsh conditions and increase yields. Alongside this work, researchers are supporting farmers to adopt better agronomic practices, such as minimum tillage farming, crop rotation, proper spacing and planting date practices, the use of terracing or intercropping, or techniques to reduce water use.

Of course, breeding cannot happen in a vacuum. To protect soils and produce quality yields, these cropping measures should be closely matched to the best, context-appropriate soil management practices available to farmers, for instance around the type and timing of mineral fertilizer, along with organic sources like crop residues, compost or manure.

Indeed, a combination will bring the best results.  But most of the time accessing either improved variety or best agronomic practice represent a challenge for farmers in low income countries.

Here are three ways crop breeders can ensure they deliver the best seeds and create the best conditions for long-term crop production.

Include farmers, agronomic experts and extension services when defining product requirements

Strong connections among public breeding programs and extension and agronomic groups are vital. There is growing discussion regarding how to broaden our work to better consider all the factors that contribute to a successful breeding scheme: genotyping, environment and management (GxExM). However, defining the management component is not easy. Do we breed for conditions that farmers are actually working with, or breed for conditions that they should adopt?

A key to answer this question is a strong breeding team defining the traits needed and wanted by farmers. To design the best product profile, it is imperative to involve extension teams and other groups that work on the development of sustainable agronomic practices.

Properly manage research stations

Attention also needs to focus on the sustainability practices within research stations. It is all too easy to find degraded soil in public research stations. There are many reasons for this: inadequate long-term planning, lack of organized management structures, insufficient connections between breeding and agronomic teams, and lack of resources, to name a few.

Public research stations must serve as an example for the farmers in that specific region. Thus, it is not only what products we develop that matters, but also how we develop them. If we develop a good variety at the research station, but do so without adopting good agronomic practice, what example has been set for farmers and future generations? We need to ensure we invest in the best soil management practices along every step of the research phase.

Breed for specific soil characteristics

Once the breeding target is known, breeding for specific soil conditions is critical. This means developing varieties for soil conditions such as nutrient deficiencies or high salinity levels. CGIAR breeding programs have put in tremendous efforts with great impact here.

For example, AfricaRice and partners developed rice varieties branded ARICA (Advanced Rice Varieties for Africa) to be salt or iron toxicity tolerant, among other traits. This is helping farmers who farm under predominantly rainfed conditions, in which soils and yields are threatened by floods, droughts and toxicity.

Another standout product is Stress Tolerant Maize for Africa (STMA), led by the International Maize and Wheat Improvement Center (CIMMYT) and the International Institute of Tropical Agriculture (IITA). Breeders have developed varieties that can thrive in low soil fertility conditions, along with resistance to other stresses such as pests and drought. The project has seen the adoption of new maize varieties by more than six million households across 13 countries, with some farms increasing yields by over 150 per cent.

Our soils depend on breeding for the future. Breeding is showing real results for improving yields, delivering better food, and increasing smallholder incomes. But its impact on ecosystems could go either way. With the right investments in relationships, good research practices, and delivering varieties matched to particular soil conditions, we can breed for the present and for the future.

It is time to invest in both crop breeding and soil management — as one vital package of innovations.

Building networks and capacity

Written by Shiela Chikulo on . Posted in News.

The active involvement of partners in the co-design of project and capacity building activities is key to the success of the Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG) project, led by the International Maize and Wheat Improvement Center (CIMMYT). To that end, the AGG Regional Collaborative Breeding and Testing Networks launched with virtual meetings on September 14 and 15 for southern African partners, and October 28 and November 2 for eastern African partners.

In addition, the AGG team collaborated with researchers from the Excellence in Breeding (EiB) Platform on a number of capacity development webinars in October and November, on topics including Continuous Improvement for breeding processes, programs and products,  enhancing and measuring genetic gain in crop breeding, and a three-webinar series on statistical analysis for plant breeders with CIMMYT’s Biometrics and Statistics Unit.

These training events and regional meetings provided opportunities for well over 100 breeders from CIMMYT, national agricultural research systems (NARS) and seed companies to refresh their capacities to improve genetic gains, and to collectively review and discuss upcoming project activities, current issues of interest, and broader project objectives within their current regional context.

Several themes of importance to partners emerged during the network virtual meetings, for attention in future AGG activities and capacity development work.

Gender inclusion and the impact of COVID-19

Ugandan partners, including Godfrey Asea, director of the National Crops Resources Research Institute at Uganda’s National Agricultural Research Organization, and Josephine Okot, founder and managing director of Victoria Seeds, applauded the project’s emphasis on inclusion of women’s knowledge and preferences in breeding programs.

“We notice that this time there is a lot of focus on gender-inclusiveness,” remarked Asea. “I can tell you there is need for enhanced capacity building for both the private sector and research in proper gender inclusion.”

They also noted the importance of building local capacity, not just for food security but also for other value chain items like raw materials. “COVID-19 has demonstrated to all policy-makers that we cannot depend on the global supply chains,” said Okot. “How can we leverage this project if, for instance, some private sector actors want to [know] the appropriate protein-content maize for, say, animal feed?”

Demand for knowledge

NARS members in Tanzania requested increased support on how to measure or assess genetic gains, especially at the national level, to allow them to establish a baseline upon which genetic gains would be pegged for the project lifecycle.

With statistics an essential element to plant breeding — from analyzing yield trials to ranking varieties — the webinar series in Statistical Analysis for Plant Breeders was a first step towards meeting these capacity development needs.

“The idea of this webinar series was to share insights on how we can improve the breeding plans using statistical methods in an effective way,” said Juan Burgueño, the head of CIMMYT’s Biometrics and Statistics Unit. “The training offered both theory and hands-on experience using open-access software.”

Reaching farmers

Looking beyond breeding, meeting participants also discussed how to improve access and adoption of improved varieties among farmers.

“For a large country such as Tanzania, it is at times very hard to reach the farmers,” said Zabron Mbwaga, managing director of the Tanzania-based Beula Seed Company and Consultancy Limited. “We may have a lot of seed in the store, but how to get the farmers to adopt the newer varieties is quite difficult. This is more so when farmers tend to stick to varieties which they know well and are always reluctant to adopt the new varieties,” he explained.

“We need to put in a lot of effort to set up demonstration farms and enhance other awareness-raising activities such as radio programs so that farmers can know about the new varieties.”

This interest in working with smallholder farmers along the entire value chain was echoed by partners in southern Africa.

“Through this project, we would like to explore ways of collaborating along the whole value chain — as the Agriculture Research Council, other partners and small to medium enterprises — to make it an effective chain,” said Kingstone Mashingaidze, senior research manager at the South Africa Agricultural Research Council. “By planning together, we can identify best-fits for all activities in the value chain and ultimately benefit the smallholder farmers.”

About the AGG Regional Collaborative Breeding and Testing Networks

The AGG Regional Collaborative Breeding and Testing Networks aim to improve breeding efficiencies among partners by enabling the use of modern tools and approaches and enriching the existing network of research organizations, public and private seed companies, farmers’ organizations, non-governmental organizations and community-based organizations. It is expected that these networks will lead to increased efficiency and communications across the partnership network and within countries, improved sharing of best practices and protocols, and increased collective ownership of products for accelerated variety development and turnover.

The virtual meetings for the Regional Collaborative Breeding and Testing Network for southern Africa convened participants from Malawi, Mozambique, South Africa, Zambia and Zimbabwe, while meetings for eastern Africa had participants from Ethiopia, Kenya, Tanzania and Uganda.

“CIMMYT is at my heart”

Written by Madeline Dahm on . Posted in Features.

After a 37-year career, Hans-Joachim Braun is retiring from the International Maize and Wheat Improvement Center (CIMMYT). As the director of the Global Wheat Program and the CGIAR Research Program on Wheat, Braun’s legacy will resonate throughout halls, greenhouses and fields of wheat research worldwide.

We caught up with him to capture some of his career milestones, best travel stories, and vision for the future of CIMMYT and global wheat production. And, of course, his retirement plans in the German countryside.

Major career milestones

Native to Germany, Braun moved to Mexico in 1981 to complete his PhD research at CIMMYT’s experimental station in Obrégon, in the state of Sonora. His research focused on identifying the optimum location to breed spring wheat for developing countries — and he found that Obrégon was in fact the ideal location.

His first posting with CIMMYT was in Turkey in 1985, as a breeder in the International Winter Wheat Improvement Program (IWWIP). This was the first CGIAR breeding program hosted by a CIMMYT co-operator, that later developed into the joint Turkey, CIMMYT and the International Center for Agricultural Research in the Dry Areas (ICARDA) winter wheat program. “In 1990, when the Commonwealth of Independent States was established, I saw this tremendous opportunity to work with Central Asia to develop better wheat varieties,” he said. “Today, IWWIP varieties are grown on nearly 3 million hectares.”

Although Braun was determined to become a wheat breeder, he never actually intended to spend his entire career with one institution. “Eventually I worked my entire career for CIMMYT. Not so usual anymore, but it was very rewarding. CIMMYT is at my heart; it is what I know.”

“Make the link to the unexpected”

One of Braun’s standout memories was a major discovery when he first came to Turkey.  When evaluating elite lines from outside the country — in particular lines from a similar environment in the Great Plains — his team noticed they were failing but nobody knew why.

Two of his colleagues had just returned from Australia, where research had recently identified micronutrient disorders in soil as a major constraint for cereal production. The team tried applying micro-nutrients to wheat plots, and it became crystal clear that zinc deficiency was the underlying cause. “Once aware that micro-nutrient disorders can cause severe growth problems, it was a minor step to identify boron toxicity as another issue. Looking back, it was so obvious. The cover picture of a FAO book on global soil analysis showed a rice field with zinc deficiency, and Turkey produces more boron than the rest of the world combined.”

“We tested the soil and found zinc deficiency was widespread, not just in the soils, but also in humans.” This led to a long-term cooperation with plant nutrition scientists from Cukurova University, now Sabanci University, in Istanbul.

But zinc deficiency did not explain all growth problems. Soil-borne diseases — cyst and lesion nematodes, and root and crown rot — were also widespread. In 1999, CIMMYT initiated a soil-borne disease screening program with Turkish colleagues that continues until today.  Over the coming decade, CIMMYT’s wheat program will make zinc a core trait and all lines will have at least 25% more zinc in the grain than currently grown varieties.

After 21 years in Turkey, Braun accepted the position as director of CIMMYT’s Global Wheat Program and moved back to Mexico.

Partnerships and friendships

Braun emphasized the importance of “mutual trust and connections,” especially with cooperators in the national agricultural research systems of partner countries. This strong global network contributed to another major milestone in CIMMYT wheat research: the rapid development and release of varieties with strong resistance to the virulent Ug99 race of wheat rust. This network, led by Cornell University, prevented a potential global wheat rust epidemic.

CIMMYT’s relationship with Mexico’s Ministry of Agriculture and the Obregón farmers union, the Patronato, is especially important to Braun.

In 1955, Patronato farmers made 200 hectares of land available, free if charge, to Norman Borlaug. The first farm community in the developing world to support research, it became CIMMYT’s principal wheat breeding experimental station: Norman Borlaug Experimental Station, or CENEB.  When Borlaug visited Obregón for the last time in 2009, the Patronato farmers had a big surprise.

“I was just getting out of the shower in my room in Obregón when I got a call from Jorge Artee Elias Calles, the president of the Patronato,” Braun recalls. “He said, ‘Hans, I’m really happy to inform you that Patronato decided to donate $1 million.’”

The donation, in honor of Borlaug’s lifetime of collaboration and global impact, was given for CIMMYT’s research on wheat diseases.

“This relationship and support from the Obregón farmers is really tremendous,” Braun says. “Obregón is a really special place to me. I am admittedly a little bit biased, because Obregón gave me a PhD.”

A worldwide perspective

Braun’s decades of international research and travel has yielded just as many stories and adventures as it has high-impact wheat varieties.

He remembers seeing areas marked with red tape as he surveyed wheat fields in Afghanistan in the 1990s, and the shock and fear he felt when he was informed that they were uncleared landmine areas. “I was never more scared than in that moment, and I followed the footsteps of the guy in front of me exactly,” Braun recalls.

On a different trip to Afghanistan, Braun met a farmer who had struggled with a yellow rust epidemic and was now growing CIMMYT lines that were resistant to it.

“The difference between his field and his neighbors’ was so incredible. When he learned I had developed the variety he was so thankful. He wanted to invite me to his home for dinner. Interestingly, he called it Mexican wheat, as all modern varieties are called there, though it came from the winter wheat program in Turkey.”

Seeing the impact of CIMMYT’s work on farmers was always a highlight for Braun.

CIMMYT’s future

Braun considers wheat research to be still in a “blessed environment” because a culture of openly-shared germplasm, knowledge and information among the global wheat community is still the norm. “I only can hope this is maintained, because it is the basis for future wheat improvement.”

His pride in his program and colleagues is clear.

“A successful, full-fledged wheat breeding program must have breeders, quantitative genetics, pathology, physiology, molecular science, wide crossing, quality, nutrition, bioinformatics, statistics, agronomy and input from economists and gender experts,” in addition to a broad target area, he remarked at an acceptance address for the Norman Borlaug Lifetime Achievement award.

“How many programs worldwide have this expertise and meet the target criteria? The Global Wheat Program is unique — no other wheat breeding program has a comparable impact. Today, around 60 million hectares are sown with CIMMYT-derived wheat varieties, increasing the annual income of farmers by around $3 billion dollars. Not bad for an annual investment in breeding of around $25 million dollars. And I don’t take credit for CIMMYT only, this is achieved through the excellent collaboration we have with national programs.”

A bright future for wheat, and for Braun

After retirement, Braun is looking forward to settling in rural Inzlingen, Germany, and being surrounded by the beautiful countryside and mountains, alongside his wife Johanna. They look forward to skiing, running, e-biking and other leisure activities.

“One other thing I will try — though most people will not believe me because I’m famous for not cooking — but I am really looking into experimenting with flour and baking,” he says.

Despite his relaxing retirement plans, Braun hopes to continue to support wheat research, whether it is through CIMMYT or through long friendships with national partners, raising awareness of population growth, the “problem of all problems” in his view.

“We have today 300 million more hungry people than in 1985. The road to zero hunger in 2030 is long and will need substantial efforts. In 1970, Organization for Economic Co-Operation and Development (OECD) countries agreed to spend 0.7% of GDP on official development assistance. Today only 6 countries meet this target and the average of all OECD countries has never been higher than 0.4%. Something needs to change to end extreme poverty — and that on top of COVID-19. The demand for wheat is increasing, and at the same time the area under wheat cultivation needs to be reduced, a double challenge. We need a strong maize and wheat program. The world needs a strong CIMMYT.”

Are solar powered irrigation systems scalable?

Climate change is a major challenge for India, which faces large-scale climate variability and is exposed to high risk. The country’s current development model reiterates the focus on sustainable growth and aims to exploit the benefits of addressing climate change alongside promoting economic growth.

The government has been heavily emphasizing the importance of solar power in India, and the Ministry of New and Renewable Energy (MNRE) recently launched an ambitious initiative to further this cause. The Pradhan Mantri-Kisan Urja Suraksha evam Utthaan Mahabhiyan (PM-KUSUM) scheme aims to support the installation of off-grid solar pumps in rural areas, and reduce dependence on the grid in grid-connected areas.

However, there has been a knowledge gap about the potential use of solar energy interventions in the context of climate change and their scalability. In an effort to bridge this gap, scientists from the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) have comprehensively synthesized existing pilot initiatives on the deployment of solar powered irrigation systems (SPIS) across different agro-climatic zones in India and tried to assess their scalability. This in turn has led to the identification of efficient and effective models for sustainable development in accordance with the region’s socioeconomic and geopolitical situation.

Solar powered irrigation systems in India

A compendium has been developed as part of the research carried out by CCAFS, in collaboration with the International Maize and Wheat Improvement Center (CIMMYT), the Borlaug Institute for South Asia (BISA), Deutsche Gesellschaft für Internationale Zusammenarbeit GmbH (GIZ) and the International Water Management Institute (IWMI).

The main objectives for bringing forth this compendium are: to qualitatively document various deployment models of SPIS and to understand the factors impacting the scalability of SPIS in India. The authors collected detailed information about the process of installing SPIS, their use and maintenance, and documented the different approaches in the form of case studies developed through primary and secondary research. They aimed to capture the key technical, social, institutional and financial attributes of the deployment approaches to enable comparative analysis and synthesis.

In total, 16 case studies from across India were documented — 1 case for centralized SPIS, 2 distributed SPIS and 13 examples for decentralized systems.  Though each of these was designed with unique objectives, detailed analysis reveals that all the cases revolve around the improvement of the three factors: accessibility, affordability and sustainability — the trinity against which all cases have been described. Grid-connected areas such as Gujarat and Maharashtra offer an immense scope of selling surplus energy being produced by SPIS, to energy-deficient electricity suppliers while areas such as Bihar and Jharkhand offer the potential for scaling the decentralized model of SPIS.

Assessing scalability

For inclusive and sustainable growth, it is important to consider the farm-level potential of solar energy use with multiple usages of energy. The compendium documents examples of the potential of solar irrigation systems in India for adaptation and mitigation benefits. It also assesses on the scalability of different deployment approaches such as solar pump fitted boats in Samastipur, Bihar, or the decentralized solar powered irrigation systems in Gujrat and West Bengal. Through the compendium, the authors study the five key stages of the scaling-up process to assess whether these initiatives are scalable and could reduce or replace fossil fuel dependence in agriculture.

While some of the documented cases are designed exclusively to address a very specific problem in a particular context, others are primarily designed as a proof-of-concept for wider applicability and policy implications — with or without suitable modifications at the time of scaling. In this compendium, both types of cases are included and assessed to understand their relevance and the potential contribution they can make in advancing the goal of solarizing irrigation and agriculture in a sustainable and effective way.

The authors conclude that all the cases have different technical, financial, and institutional aspects which complement each other, have been designed based on community needs and are in line with the larger objective of the intervention integrating three factors — accessibility, affordability and sustainability — to ensure secured availability of resources and to facilitate scalability.

Given that India is a diverse country with varied socioeconomic and geopolitical conditions, it is important to have set guidelines that lay out a plan for scaling while allowing agencies to adapt the SPIS model based on local context and realities in the field.

The first meetings of the Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG) wheat and maize science and technical steering committees — WSC and MSC, respectively — took place virtually on 25th and 28th September.

Researchers from the International Maize and Wheat Improvement Center (CIMMYT) sit on both committees. In the WSC they are joined by wheat experts from national agricultural research systems (NARS) in Bangladesh, Ethiopia, Kenya, India, and Nepal; and from Angus Wheat Consultants, the Foreign, Commonwealth & Development Office (FCDO), HarvestPlus, Kansas State University and the Roslin Institute.

Similarly, the MSC includes maize experts from NARS in Ethiopia, Ghana, Kenya and Zambia; and from Corteva, the Foundation for Food and Agriculture Research (FFAR), the International Institute for Tropical Agriculture (IITA), SeedCo, Syngenta, the University of Queensland, and the US Agency for International Development (USAID).

During the meetings, attendees discussed scientific challenges and opportunities for AGG, and developed specific recommendations pertaining to key topics including breeding and testing scheme optimization, effective engagement with partners and capacity development in the time of COVID-19, and seed systems and gender intentionality.

Discussion groups noted, for example, the need to address family structure in yield trials, to strengthen collaboration with national partners, and to develop effective regional on-farm testing strategies. Interestingly, most of the recommendations are applicable and valuable for both crop teams, and this is a clear example of the synergies we expect from combining maize and wheat within the AGG project.

All the recommendations will be further analyzed by the AGG teams during coming months, and project activities will be adjusted or implemented as appropriate. A brief report will be submitted to the respective STSCs prior to the second meetings of these committees, likely in late March 2021.

The current COVID-19 pandemic — and associated measures to reduce its spread — is projected to increase extreme poverty by 20%, with the largest increase in sub-Saharan Africa, where 80 million more people would join the ranks of the extreme poor. Accelerating the process of delivering high-quality, climate resilient and nutritionally enriched maize seed is now more critical than ever.However, developing these varieties is not a rapid or cheap process. Over the course of five years, researchers on the Stress Tolerant Maize for Africa (STMA) project developed a range of tools and technologies to reduce the overall cost of producing a new high yielding, stress tolerant hybrids for smallholder farmers in the region.

Maize breeding starts with crossing two parents and essentially ends after testing their great-great-great-great grandchildren in as many locations as possible. This allows plant breeders to identify the new varieties which will perform well in the conditions faced by their target beneficiaries — in the case of STMA, smallholder farmers in Africa. In other parts of the world, new tools and technologies are routinely added to breeding programs to help reduce the cost and time it takes to produce new varieties.

Scientists on the STMA project focused on testing and scaling new tools specifically for maize breeding programs in sub-Saharan Africa and began by taking a closer look at the most expensive part of the breeding process: phenotyping or collecting precise information on plant traits.

“Within a breeding program, phenotyping is the single most costly step,” explains CIMMYT molecular breeder Manje Gowda. “Molecular technologies provide opportunities to reduce this cost.” The research team tested two methods to speed up this step and make it more cost efficient: forward breeding and genomic selection.

Speeding up a long and costly process

Two important traits maize breeders look for in their plant progeny are susceptibility for two key maize diseases: maize streak virus (MSV) and maize lethal necrosis (MLN). In traditional breeding, breeders must extensively test lines in the field for their susceptibility to these diseases, and then remove them before the next round of crossing. This carries a significant cost.

Using a process called forward breeding, scientists can screen for DNA markers known to be associated with susceptibility to these diseases. This allows breeders to identify lines vulnerable to these diseases and remove them before field testing.

Scientists on the STMA project applied this approach in CIMMYT breeding programs in eastern and southern Africa over the past four years, saving an estimated $300,000 in field costs. Under the AGG project, research will now focus on applying forward breeding to identify susceptibility for another fast-spreading maize pest, fall armyworm, as well as extending use of this method in partners’ breeding programs.

Forward breeding is ideal for “simple” traits which are controlled by a few genes. However, other desired traits, such as tolerance to drought and low nitrogen stress, are genetically complex. Many genes control these traits, with each gene only contributing a little towards overall stress tolerance.

In this case, a technology called genomic selection can be of service. Genomic selection estimates the performance, or breeding value, of a line based largely on genetic information. Genomic selection uses more than 5,000 DNA markers, without the need for precise information about what traits these markers control. The method is ideal for complicated traits such as drought and low nitrogen stress tolerance, where hundreds of small effect genes together largely control how a plant grows under these stresses.

CIMMYT scientists used this technology to select and advance lines for drought tolerance. They then tested these lines and compared their performance in the field to lines selected conventionally. They found that the two sets of resulting hybrid varieties — those advanced using genomic selection and those advanced in the field — showed the same grain yield under drought stress. However, genomic selection only required phenotyping half the lines, achieving the same outcome with half the budget.

Innovations in the field

While DNA technology is reducing the need for extensive field phenotyping, research is also underway to reduce the cost of the remaining necessary phenotyping in the field.

Typically, many traits — such as plant height or leaf drying under drought stress — are measured by hand, using the labor of large teams of people. For example, plant and ear height is traditionally measured by a team of two using a meter stick.

Mainasarra Zaman-Allah, a CIMMYT abiotic stress phenotyping specialist based in Zimbabwe, has been developing faster, more accurate ways to measure these traits.  He implemented the use of a small laser sensor to measure plant and ear height which only requires one person. This simple yet cost effective tool has reduced the cost of measuring these traits by almost 60%. Similarly, using a UAV-based platform has reduced the cost of measuring a trait known as canopy senescence — leaf drying associated with drought susceptibility —by over 65%.

The identification of plants which are tolerant to key diseases has traditionally involved scoring the severity of disease in each plot visually, but walking through hundreds of plots daily can lead to errors in human judgement. To combat this, CIMMYT biotic stress phenotyping specialist LM Suresh collaborated with Jose Luis Araus and Shawn Kefauver, scientists at the University of Barcelona, Spain, to develop image analysis software that can quantify disease severity, thereby avoiding problems associated with unintentional human bias.

Plant breeders need uniform, or homozygous, lines for selection. With conventional plant breeding this is difficult: no matter how many times you cross a line, a small amount of DNA will remain heterozygous — having two different alleles of a particular gene — and reduce accuracy in line selection.

A technology called doubled haploid allows breeders to develop homozygous lines within two seasons. While this technology has been used in temperate maize breeding programs since the 1990s, it was not available for tropical environments until 10 years ago. In 2013, thanks to joint work with Kenyan partners at the CIMMYT Doubled Haploid facility in Kiboko, this technology was made available to African breeding programs. Now Vijay Chaikam, a CIMMYT doubled haploid specialist based in Kenya, is working towards reducing the cost of this technology as well.

The efforts begun by the STMA research team is now continuing under the Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG) project. As this work is carried forward, the next crucial step is ensuring that the next generation of African maize breeders have access to these technologies and tools.

“Improving national breeding programs will really drive success in raising maize yields in the stress prone environments faced by many farmers in our target countries,” says Mike Olsen, CIMMYT’s upstream trait pipeline coordinator. Under AGG, in collaboration with the CGIAR Excellence in Breeding Program, these tools will be scaled out.

International Whole Grain Day 2020

Written by Steven M on . Posted in Features.

The International Maize and Wheat Improvement Center (CIMMYT) is proud to partner with the Whole Grain Initiative in celebrating International Whole Grain Day on November 19, 2020.

In terms of diet and nutrition, ours is an age of contradiction. While populations in wealthy countries are faced with unprecedented levels of diet-related disease, close to 2 billion people globally remain food insecure. At the same time, global agriculture has an enormous role to play in the transition towards an environmentally sustainable future.

International Whole Grain Day 2020 is a good day to step back and consider the continued role of whole grains in the healthy, sustainable diets of today and tomorrow. Explore our content to learn what whole grains are, how we’re working to make whole grain wheat and maize even more nutritious, and discover some our favorite recipes.
