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.

Reaching women with improved maize and wheat

By 2050, global demand for wheat is predicted to increase by 50 percent from today’s levels and demand for maize is expected to double. Meanwhile, these profoundly important and loved crops bear incredible risks from emerging pests and diseases, diminishing water resources, limited available land and unstable weather conditions – with climate change as a constant pressure exacerbating all these stresses.

Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG) is a new 5-year project led by the International Maize and Wheat Improvement Center (CIMMYT) that brings together partners in the global science community and in national agricultural research and extension systems to accelerate the development of higher-yielding varieties of maize and wheat.

Funded by the Bill & Melinda Gates Foundation, the UK Foreign, Commonwealth & Development Office, the U.S. Agency for International Development (USAID) and the Foundation for Food and Agriculture Research (FFAR), AGG fuses innovative methods to sustainably and inclusively improve breeding efficiency and precision to produce seed varieties that are climate-resilient, pest- and disease-resistant, highly nutritious, and targeted to farmers’ specific needs.

AGG seeks to respond to the intersection of the climate emergency and gender through gender-intentional product profiles for its improved seed varieties and gender-intentional seed delivery pathways.

AGG will take into account the needs and preferences of female farmers when developing the product profiles for improved varieties of wheat and maize. This will be informed by gender-disaggregated data collection on current varieties and preferred characteristics and traits, systematic on-farm testing in target regions, and training of scientists and technicians.

To encourage female farmers to take up climate-resilient improved seeds, AGG will seek to understand the pathways by which women receive information and improved seed and the external dynamics that affect this access and will use this information to create gender-intentional solutions for increasing varietal adoption and turnover.

“Until recently, investments in seed improvement work have not actively looked in this area,” said Olaf Erenstein, Director of CIMMYT’s Socioeconomics Program at a virtual inception meeting for the project in late August 2020. Now, “it has been built in as a primary objective of AGG to focus on [
] strengthening gender-intentional seed delivery systems so that we ensure a faster varietal turnover and higher adoption levels in the respective target areas.”

In the first year of the initiative, the researchers will take a deep dive into the national- and state-level frameworks and policies that might enable or influence the delivery of these new varieties to both female and male farmers. They will analyze this delivery system by mapping the seed delivery paths and studying the diverse factors that impact seed demand. By understanding their respective roles, practices, and of course, the strengths and weaknesses of the system, the researchers can diagnose issues in the delivery chain and respond accordingly.

Once this important scoping step is complete, the team will design a research plan for the following years to understand and influence the seed information networks and seed acquisition. It will be critical in this step to identify some of the challenges and opportunities on a broad scale, while also accounting for the related intra-household decision-making dynamics that could affect access to and uptake of these improved seed varieties.

“It is a primary objective of AGG to ensure gender intentionality,” said Kevin Pixley, Director of CIMMYT’s Genetic Resources Program and AGG project leader. “Often women do not have access to not only inputs but also information, and in the AGG project we are seeking to help close those gaps.”

Lessons for gender in seed systems

Seed systems are complex and dynamic, involving diverse, interdisciplinary actors. Women play an important role in the seed value chain, although underlying social and cultural norms can impact their equal participation. Gender-sensitive seed systems will create more opportunities for women and increase food security.

The International Maize and Wheat Improvement Center (CIMMYT) convened a multi-stakeholder technical workshop titled, “Gender dynamics in seed systems in sub-Saharan Africa and worldwide lessons” on December 2, 2019, in Nairobi, Kenya. Researchers and development practitioners operating in the nexus of gender and seed systems shared lessons learned and research findings to identify knowledge gaps and exchange ideas on promising — and implementable — interventions and approaches that expand opportunities for women in the seed sector.

Plan to improve wheat output under works

CIMMYT Country Representative in Pakistan Dr Muhammad Imtiaz briefed National Food Security Minister Fakhr Imam on the potential strategy to increase use of high-yielding, climate resilient and rust-resistant seed varieties; closing the yield gap by timely sowing and optimal use thereby formulating and applying the right policy; and ensuring good support price in place.

Historic wheat research station poised to host cutting-edge research

It was the site where International Maize and Wheat Improvement Center (CIMMYT) scientist Norman Borlaug famously received news of his 1970 Nobel Peace Prize win. Now, Toluca station will become CIMMYT’s new testing site for rapid generation advancement and speed breeding in wheat – a method that accelerates generation advancement of crops and shortens the breeding cycle using tools like continuous lighting and temperature control.

The Toluca wheat experimental station is one of CIMMYT’s five experimental stations in Mexico, located in a picturesque town on the outskirts of Mexico’s fifth largest city, Toluca, about 60 kilometers southwest of Mexico City. The station was strategically chosen for its cool, humid conditions in summer. These conditions have made it an ideal location for studying wheat resistance to deadly diseases including yellow rust and Septoria tritici blotch.

Since its formal establishment in 1970, Toluca has played a key role in CIMMYT’s wheat breeding program. The site is also of significant historical importance due to its origins as a testing ground for Borlaug’s shuttle breeding concept in the 1940s, along with Ciudad Obregón in the Sonora state of northern Mexico. The breeding method allowed breeders to plant at two locations to advance generations and half the breeding cycle of crops.

Applying this unorthodox breeding method, Borlaug was able to advance wheat generations twice as fast as standard breeding programs. Planting in contrasting environments and day lengths — from the cool temperatures and high rainfall of Toluca to the desert heat of Ciudad Obregón — also allowed Borlaug and his colleagues to develop varieties that were more broadly adaptable to a variety of conditions. His shuttle breeding program was so successful that it provided the foundations of the Green Revolution.

Toluca was also the site where the first sexual propagation of the destructive plant pathogen Phytophtora infestans was reported. The deadly pathogen is best known for causing the potato late blight disease that triggered the Irish potato famine.

New life for the historic station

More than 50 years since its establishment, the station will once again host cutting-edge innovation in wheat research, as the testing ground for a new speed breeding program led by wheat scientists and breeders from Accelerating Genetic Gains in Maize and Wheat (AGG).

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), AGG aims to accelerate the development and delivery of more productive, climate-resilient, gender-responsive, market-demanded, and nutritious maize and wheat varieties.

While most breeding programs typically take between 7-8 years before plants are ready for yield testing, shuttle breeding has allowed CIMMYT to cut the length of its breeding programs in half, to just 4 years to yield testing. Now, AGG wheat breeders are looking to shorten the breeding cycle further, through rapid generation advancement and speed breeding.

“The AGG team will use a low-cost operation, in-field screenhouse, spanning 2 hectares, to grow up to 4 generations of wheat per year and develop new germplasm ready for yield testing within just 2 years,” said Ravi Singh, CIMMYT distinguished scientist and head of wheat improvement. “This should not only save on cost but also help accelerate the genetic gain due to a significant reduction in time required to recycle best parents.”

Construction of the new rapid generation advancement and speed breeding facilities is made possible by support from the Bill and Melinda Gates Foundation and DFID through Delivering Genetic Gain in Wheat (DGGW), a 4-year project led by Cornell University, which ends this year. It is expected to be complete by September.

The concept of speed breeding is not new. Inspired by NASA’s efforts to grow crops in space, scientists at the University of Sydney, the University of Queensland (UQ) and the John Innes Centre developed the technique to accelerate the development of crops and improve their quality. The breeding method has been successfully used for crops like spring wheat, barley, pea, chickpea, radish and canola.

CIMMYT Global Wheat Program Director Hans Braun highlighted the importance of testing the new breeding scheme. “Before completely adopting the new breeding scheme, we need to learn, optimize and analyze the performance results to make necessary changes,” he said.

If all goes well, Toluca could once again be on the vanguard of wheat research in the near future.

“We plan to use the speed breeding facility for rapid integration of traits, such as multiple genes for resistance, to newly-released or soon to be released varieties and elite breeding lines,” said CIMMYT Wheat Breeder Suchismita Mondal, who will lead the work in these facilities. We are excited to initiate using the new facilities.”

Work to develop high yielding Striga tolerant maize seed is bearing fruit

Striga, an invasive parasitic weed with purple-colored flowers, looks striking and harmless. But, beyond that mark of beauty, is a nutrient-sucking monster that stunts crops such as maize and sorghum, leaving affected farmers counting losses.

Witchweed thrives in poor soils with low rainfall conditions. It is prevalent in farming systems with poor crop management practices and in communities where farmers use minimal or no fertilizer. Once maize begins germinating in Striga-prevalent soil, it stimulates Striga seeds to germinate. Striga then attaches to the roots of the host plant, sapping nutrients from the plant, leading to stunting. The potential yield loss can reach up to 100%. Some farmers attempt to uproot it once they notice it germinating alongside their maize plantation, but this is often too late because damage is done as soon as the parasite attaches to the maize roots. When mature, the weed deposits tens of thousands of tiny seeds into the soil. This makes it very difficult for farmers to get rid of it.

To tackle this challenge, farmers need to apply inorganic fertilizer, which is not always affordable, or animal manure to enrich the soil before planting. They are also advised by researchers and extensionists to practice crop rotation or intercropping with legumes such as beans, soybean or groundnuts that restrict Striga’s germination.  In the Assessment of Management Options on Striga Infestation and Maize Grain Yield in Kenya, for example, researchers recommend that Striga control measures include a combination of herbicide-resistant or maize varieties with native genetic resistance intercropped with legumes.

Nevertheless, while a few control measures have been moderately successful, the problem still persists, especially in western Kenya, eastern Uganda and lake zone of Tanzania, where farmers have frequently voiced their frustrations at the ubiquity of this invasive weed.

“While crop rotation with crops such as soybean or beans may break the cycle of Striga, its seed can stay in the soil and remain viable for up to 10 years,” says Dan Makumbi, a maize breeder with the International Maize and Wheat Improvement Center (CIMMYT), who is leading research efforts against the witchweed.

A blow to optimal yield potential

Maize is a staple crop that is predominantly cultivated by smallholder farmers in western Kenya and the lake region. It is an important source of food security and livelihoods of millions of people in the region, but constraints such as Striga prevent farmers from obtaining the crop’s ideal potential.

“The yield loss would have been adequate to cover my family’s food requirements for a year,” Naliaka said. “From two farming seasons, I could harvest a sufficient quantity of maize and sell some surplus to pay my children’s school fees. With the Striga menace, all that is but a dream.”

Just like Naliaka, Norah Kayugi, a 40-year-old widowed mother of six children from Siaya County in Kenya, has seen her maize production fall to less than 8 bags of 90kgs per acre. In normal circumstances, they would obtain at least 16 bags of maize per acre. The significant yield loss sets back many affected households in a big way, as they experience food shortage only a few months after harvest. Some divert their reduced incomes for food purchases, possibly leaving other priorities such as health and education of their children unattended.

Kayugi, who has been a farmer since 1997, now takes on casual jobs to supplement her farming in order to support her family, being the sole breadwinner following her husband’s demise years ago. “I plant vegetables, beans and maize to sustain my family. My one-acre farm yields about 10 bags of 90ks each. But I know for sure that were it not for this weed, the yield potential could reach 30 bags of 90kgs each per acre.”

Standing up to multiple farming stresses

These smallholders, like their counterparts elsewhere in sub-Saharan Africa, already face other farming challenges, including climate change-induced droughts, pests such as the fall armyworm, diseases like maize lethal necrosis (MLN), and declining soil fertility, among others. While CIMMYT has registered breakthroughs in developing maize varieties that tolerate such stresses, on-going efforts against Striga are also taking shape, challenges notwithstanding.

The development and deployment of the imazapyr-resistant (IR) maize has been one such instance of effective Striga control. With this method, herbicide-resistant maize seeds are coated with herbicide.  The seed germinates and absorbs some of the herbicide used to coat it. The germinating maize stimulates Striga to germinate and as it attaches to the maize root, it is killed before it can cause any damage. Despite its effectiveness, sustaining this technology presented a major challenge to seed companies.

“It was costly for seed companies, as they needed to establish and sustain the operation of separate seed treatment units dedicated to production of the herbicide-coated maize seed. Once you establish a line to dress the seed with the chemical, you cannot use it to treat any other seeds as the chemical will destroy them,” said Makumbi.

Seed companies — like NASECO in Uganda, Kenya Seed Company in Kenya, Western Seed Company and FreshCo in Kenya, and Meru Agro in Tanzania — obtained financial and technical support from a partnership initiative coordinated by African Agricultural Technology Foundation (AATF) and backed by CIMMYT to scale commercialisation of StrigAwayTM maize in East Africa. The initiative was funded by USAID’s Feed the Future Partnering for Innovation program through Fintrac and it supported the seed companies to establish seed treatment facilities to handle herbicide resistant maize. This allowed each of the companies to have a fully dedicated facility for herbicide resistant maize seed processing. “Right now, herbicide resistant maize hybrid seed is available on the market in Kenya, Tanzania and Uganda,” Makumbi said.

Native hope

In the past few years, Makumbi and his team, in collaboration with the International Institute for Tropical Agriculture (IITA) and the Kenya Agricultural and Livestock Research Organization (KALRO), have redirected their efforts towards breeding for native genetic resistance to Striga. This means developing seeds which are naturally resistant to Striga, reducing the need for herbicides. The early indication is that there are several parental lines showing potential to tolerate or resist Striga, and these are being used to develop hybrids. The hybrids, which offer multiple benefits for farmers, are under wide scale testing in Kenya.

“In our tests, we are not only looking at Striga resistance alone but also other important traits such as good yield under optimal conditions, drought stress and low soil fertility, resistance to major foliar diseases including gray leaf spot, Turcicum leaf blight, maize streak virus and ear rots,” Makumbi noted.

As these breeding efforts continue, there is light at the end of the tunnel. The hope of farmers taking back full control of their maize farms from Striga’s “bewitching ways” in the near future remains alive.

Breaking Ground: Sudha Nair helps bridge gap between maize breeding and genetics

Sudha Nair is inspired every day by her passion for biology and genetics. The senior scientist at the International Maize and Wheat Improvement Center (CIMMYT) based in Hyderabad, India, works to define and practice the best strategies for applying genomics in agriculture.

“I always knew that science is what I would love to pursue,” said Sudha, an alumnus of both the Indian Agricultural Research Institute (IARI) in New Delhi and the National Institute of Agrobiological Sciences in Japan.

Originally from Kerala, India, Sudha did not expect a career in agriculture. “I studied for engineering after my high school as I was selected for that course before I was selected for the biology stream. It didn’t take me even a single moment to decide to leave the course six months later when I was selected for the undergraduate program in agriculture,” Sudha said. “I can’t say that it is love for agriculture that forced me to choose the field I am in, but it is the fascination for biological science. I love genetics and I love research; as long as I get to do this as part of my job, I am happy.”

Sudha’s first experience working with CIMMYT involved her PhD dissertation at IARI, which was a part of research conducted for the Asian Maize Biotechnology Network (AMBIONET), led by CIMMYT. “I had always looked at CIMMYT as an organization doing high quality applied science,” she said.

Starting in 2010 as a consultant for the Drought Tolerant Maize for Africa (DTMA) project, Sudha then interviewed for the position of maize fine-mapping specialist in 2011 and was selected as a scientist.  Her career at CIMMYT has now spanned close to a decade.

Her role involves implementation of molecular breeding in the maize breeding program in Asia. This includes discovery, validation and application of molecular markers for prioritized traits, genomic selection, and marker-based quality assurance and quality control in maize breeding – through current and past projects like Heat Tolerant Maize for Asia (HTMA), Climate Resilient Maize for Asia (CRMA) and the CGIAR Research Program on Maize (MAIZE).  Apart from this, she is currently involved in the Accelerating Genetic Gains in Maize and Wheat (AGG) project for incorporating elite and stress tolerance genetics from Asia in the elite African maize germplasm.

Sudha has been a part of a number of global maize projects including the Stress Tolerant Maize for Africa (STMA) project, which developed improved maize varieties tolerant to stresses such as drought and diseases, and HarvestPlus in maize, developing nutritionally enriched maize cultivars. She has also played a key role in developing CIMMYT’s second-generation tropicalized haploid inducers using marker-assisted breeding.

Bringing genetics and breeding together

Sudha is grateful for the role of CIMMYT in increasing acceptance and use of genomics in breeding programs. “When I started off as a graduate student, any work related to molecular genetics was called biotechnology, and we were considered as a different “breed”, who worked in silos to spend resources on “upstream research”, and whose results never saw any breeding applications. Breeding and molecular genetics were like parallel lines that would never meet,” she explained.

“In course of time, the research communities in applied breeding institutes like CIMMYT have brought about changes in strategies, goals, and more importantly, attitudes, and now all of us work towards one major goal of developing impactful products (varieties) for benefiting resource-constrained farming communities worldwide. All in all, I and my colleagues in the upstream research team in CIMMYT Global Maize Program have an important responsibility of providing core support to the breeding and seed systems teams in developing and delivering impactful products.”

When asked what the most enjoyable part of her work is, Sudha cited the practicality and applicability of her work. “Basically, my job responsibility is to design and implement the best strategies for applying genomics in maize breeding to achieve higher genetic gains,” she explained. “Being in an organization like CIMMYT, what is most satisfying about the role I am in is the translation of upstream research into tools for improving breeding efficiency and in turn into impactful maize varieties that the farming communities around the world cultivate.”

More than 100 scientists, crop breeders, researchers, and representatives from funding and national government agencies gathered virtually to initiate the wheat component of a groundbreaking and ambitious collaborative new crop breeding project led by the International Maize and Wheat Improvement Center (CIMMYT).

The new project, Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods, or AGG, brings together partners in the global science community and in national agricultural research and extension systems to accelerate the development of higher-yielding varieties of maize and wheat — two of the world’s most important staple crops.

Funded by the Bill & Melinda Gates Foundation, the U.K. Department for International Development (DFID), the U.S. Agency for International Development (USAID), and the Foundation for Food and Agriculture Research (FFAR), the project specifically focuses on supporting smallholder farmers in low- and middle-income countries. The international team uses innovative methods — such as rapid cycling and molecular breeding approaches — that improve breeding efficiency and precision to produce varieties that are climate-resilient, pest and disease resistant and highly nutritious, targeted to farmers’ specific needs.

The wheat component of AGG builds on breeding and variety adoption work that has its roots with Norman Borlaug’s Nobel Prize winning work developing high yielding and disease resistance dwarf wheat more than 50 years ago. Most recently, AGG builds on Delivering Genetic Gain in Wheat (DGGW), a 4-year project led by Cornell University, which ends this year.

“AGG challenges us to build on this foundation and make it better, faster, equitable and sustainable,” said CIMMYT Interim Deputy Director for Research Kevin Pixley.

At the virtual gathering on July 17, donors and partner representatives from target countries in South Asia joined CIMMYT scientists to describe both the technical objectives of the project and its overall significance.

“This program is probably the world’s single most impactful plant breeding program. Its products are used throughout the world on many millions of hectares,” said Gary Atlin from the Bill & Melinda Gates Foundation. “The AGG project moves this work even farther, with an emphasis on constant technological improvement and an explicit focus on improved capacity and poverty alleviation.”

Alan Tollervey from DFID spoke about the significance of the project in demonstrating the relevance and impact of wheat research.

“The AGG project helps build a case for funding wheat research based on wheat’s future,” he said.

Nora Lapitan from the USAID Bureau for Resilience and Food Security listed the high expectations AGG brings: increased genetic gains, variety replacement, optimal breeding approaches, and strong collaboration with national agricultural research systems in partner countries.

Reconnecting with trusted partners

The virtual meeting allowed agricultural scientists and wheat breeding experts from AGG target countries in South Asia, many of whom have been working collaboratively with CIMMYT for years, to reconnect and learn how the AGG project both challenges them to a new level of collaboration and supports their national wheat production ambitions.

“With wheat blast and wheat rust problems evolving in Bangladesh, we welcome the partnership with international partners, especially CIMMYT and the funders to help us overcome these challenges,” said Director General of the Bangladesh Wheat and Maize Research Institute Md. Israil Hossain.

Director of the Indian Institute for Wheat and Barley Research Gyanendra P. Singh praised CIMMYT’s role in developing better wheat varieties for farmers in India.

“Most of the recent varieties which have been developed and released by India are recommended for cultivation on over 20 million hectares. They are not only stress tolerant and high yielding but also fortified with nutritional qualities. I appreciate CIMMYT’s support on this,” he said.

Executive Director of the National Agricultural Research Council of Nepal Deepak K. Bhandari said he was impressed with the variety of activities of the project, which would be integral to the development of Nepal’s wheat program.

“Nepal envisions increased wheat productivity from 2.84 to 3.5 tons per hectare within five years. I hope this project will help us to achieve this goal. Fast tracking the replacement of seed to more recent varieties will certainly improve productivity and resilience of the wheat sector,” he said.

The National Wheat Coordinator at the National Agricultural Research Center of Pakistan, Atiq Ur-Rehman, told attendees that his government had recently launched a “mega project” to reduce poverty and hunger and to respond to climate change through sustainable intensification. He noted that the support of AGG would help the country increase its capacity in “vertical production” of wheat through speed breeding. “AGG will help us save 3 to 4 years” in breeding time,” he said.

For CIMMYT Global Wheat Program Director Hans Braun, the gathering was personal as well as professional.

“I have met many of you over the last decades,” he told attendees, mentioning his first CIMMYT trip to see wheat programs in India in 1985. “Together we have achieved a lot — wheat self-sufficiency for South Asia has been secured now for 50 years. This would not be possible without your close collaboration, your trust and your willingness to share germplasm and information, and I hope this will stay. “

Braun pointed out that in this project, many national partners will gain the tools and capacity to implement their own state of the art breeding strategies such as genomic selection.

“We are at the beginning of a new era in breeding,” Braun noted. “We are also initiating a new era of collaboration.”

The wheat component of AGG serves more than 30 million wheat farming households in Bangladesh, Ethiopia, India, Kenya, Nepal and Pakistan. A separate inception meeting for stakeholders in sub-Saharan Africa is planned for next month.

New project to ramp up genetic gains in maize for better livelihoods

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) and the U.S. Agency for International Development (USAID).

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.

Accelerating Genetic Gains in Maize and Wheat (AGG)

Accelerating Genetic Gains in Maize and Wheat (AGG)

Accelerating Genetic Gains in Maize and Wheat (AGG), a project led by the International Maize and Wheat Improvement Center (CIMMYT), brings together partners in the global science community and in national agricultural research and extension systems to accelerate the development of higher-yielding varieties of maize and wheat — two of the world’s most important staple crops.

Specifically focusing on supporting smallholder farmers in low- and middle-income countries, the project uses innovative methods that improve breeding efficiency and precision to produce varieties that are climate-resilient, pest- and disease-resistant, and highly nutritious, targeted to farmers’ specific needs.

The maize component of the project serves 13 target countries: Ethiopia, Kenya, Malawi, Mozambique, South Africa, Tanzania, Uganda, Zambia and Zimbabwe in eastern and southern Africa; and Benin, Ghana, Mali, and Nigeria in West Africa. The wheat component of the project serves six countries: Bangladesh, India, Nepal, and Pakistan in South Asia; and Ethiopia and Kenya in sub-Saharan Africa.

This project builds on the impact of the Delivering Genetic Gain in Wheat (DGGW) and Stress Tolerant Maize for Africa (STMA) projects.

Objectives

The project aims to accelerate the development and delivery of more productive, climate-resilient, gender-responsive, market-demanded, and nutritious maize and wheat varieties in support of sustainable agricultural transformation in sub-Saharan Africa and South Asia.

To encourage adoption of new varieties, the project works to improve equitable access, especially by women, to seed and information, as well as capacity building in breeding, disease surveillance, and seed marketing.

Funders

Project funding is provided by the Bill & Melinda Gates Foundation, the UK Foreign, Commonwealth & Development Office, the United States Agency for International Development and the Foundation for Food and Agricultural Research (FFAR).

Key partners

The primary partners for this project are the national agricultural research systems in the project target countries and, for the maize component, the International Institute for Tropical Agriculture (IITA) and small and medium enterprise (SME) seed companies.

Supporting smallholder farmers to better combat drought

Researchers from the Cereal Systems Initiative for South Asia (CSISA) project have been exploring the drivers of smallholder farmers’ underuse of groundwater wells to combat in-season drought during the monsoon rice season in Nepal’s breadbasket — the Terai region.

Their study, published in Water International, finds that several barriers inhibit full use of groundwater irrigation infrastructure.

Inconsistent rainfall has repeatedly damaged paddy crops in Nepal over the last years, even though most agricultural lands are equipped with groundwater wells. This has contributed to missed national policy targets of food self-sufficiency and slow growth in cereal productivity.

A key issue is farmers’ tendency to schedule irrigation very late in an effort to save their crops when in-season drought occurs. By this time, rice crops have already been damaged by lack of water and yields will be decreased. High irrigation costs, especially due to pumping equipment rental rates, are a major factor of this aversion to investment. Private irrigation is also a relatively new technology for many farmers making water use decisions.

After farmers decide to irrigate, queuing for pumpsets, tubewells, and repairs and maintenance further increases irrigation delays. Some villages have only a handful of pumpsets or tubewells shared between all households, so it can take up to two weeks for everybody to irrigate.

To address these issues, CSISA provides suggestions for three support pathways to support farmers in combatting monsoon season drought:

1. Raise awareness of the importance of timely irrigation

To avoid yield penalties and improve operational efficiency through better-matched pumpsets, CSISA has raised awareness through agricultural FM radio broadcasts on the strong relationship between water stress and yield penalties. Messages highlight the role of the plough pan in keeping infiltration rates low and encouraging farmers to improve irrigation scheduling. Anecdotal evidence suggests that improved pump selection may decrease irrigation costs by up to 50%, and CSISA has initiated follow-up studies to develop recommendations for farmers.

Social interaction is necessary for purchasing fuel, transporting and installing pumps, or sharing irrigation equipment. These activities pose risks of COVID-19 exposure and transmission and therefore require farmers to follow increased safety and hygiene practices, which may cause further delays to irrigation. Raising awareness about the importance of timely irrigation therefore needs to go hand in hand with the promotion of safe and hygienic irrigation practices. This information has been streamlined into CSISA’s ongoing partnerships and FM broadcasts.

2. Improve community-level water markets through increased focus on drought preparedness and overcoming financial constraints

Farmers can save time by taking an anticipatory approach to the terms and conditions of rentals, instead of negotiating them when cracks in the soil are already large. Many farmers reported that pump owners are reluctant to rent out pumpsets if renters cannot pay up front. Given the seasonality of cash flows in agriculture, pro-poor and low interest credit provisions are likely to further smoothen community-level water markets.

3. Prioritize regional investment

The study shows that delay factors differ across districts and that selectively targeted interventions will be most useful to provide high returns to investments. For example, farmers in Kailali reported that land access issues — due to use of large bullock carts to transport pumpsets — and fuel shortages constitute a barrier for 10% and 39% of the farmers, while in Rupandehi, maintenance and tubewell availability were reported to be of greater importance.

As drought is increasingly threatening paddy production in Nepal’s Terai region, CSISA’s research shows that several support pathways exist to support farmers in combatting droughts. Sustainable water use can only be brought up to a scale where it benefits most farmers if all available tools including electrification, solar pumps and improved water level monitoring are deployed to provide benefits to a wide range of farmers.
