A newly published special issue in the journal Outlook on Agriculture features views and experiences on seed systems performance in Sub-Saharan Africa and options to drive faster uptake of new crop varieties. The contributions reflect the breadth of perspectives and expertise within CGIAR and beyond and make the case for the need for more demand-oriented variety development and seed delivery.
A seed system refers to the various actors, processes, and relationships that allow for the production, conservation, exchange and use of propagation materials for crops, trees, forages, livestock, and fish. For the International Maize and Wheat Improvement Center (CIMMYT), seed systems involve private seed companies, retailers, and government research agencies, among others, that are involved in the design, testing, production and distribution of high-yielding, climate-resilient, and pest- and disease-resistant maize hybrids.
“A well-functioning seed system is critical for ensuring that farmers have reliable access to the quality seeds that they want. It forms the critical link between breeders and the small-scale farmers responsible for much of the food production in Sub-Saharan Africa, Latin America and South Asia,” said CIMMYT Senior Economist Jason Donovan, who co-authored the introductory article.
“The papers in this collection raise important issues which up to now have not received enough attention, to include the strategies, capacities and incentives of the private sector to invest in the distribution of new varieties. The topics discussed have implications for the One CGIAR in its ongoing efforts to develop a coherent and coordinated seed system research program that supports accelerated varietal uptake and turnover through effective seed delivery,” he added.
CIMMYT researchers contributed two papers, one which looks at the role of different types of seed producers and traders in shaping seed systems performance and another which proposes new directions for research on gender and formal maize seed systems. The special edition grew out of the CGIAR Community of Excellence for Seed Systems Development where CIMMYT led the discussion on seed value chains and private sector linkages.
One consensus among the authors is that a wider range of partnerships will be required to reenforce the potential of seed systems to delivery more new varieties to small-scale farmers in less time.
How does CIMMYT’s improved maize get to the farmer?
The International Maize and Wheat Improvement Center (CIMMYT) is offering a new set of elite, improved maize hybrids to partners for commercialization in eastern Africa and similar agro-ecological zones. National agricultural research systems (NARS) and seed companies are invited to apply for licenses to register and commercialize these new hybrids, in order to bring the benefits of the improved seed to farming communities.
The deadline to submit applications to be considered during the first round of allocations is February 11, 2022. Applications received after that deadline will be considered during the following round of product allocations.
Information about the newly available CIMMYT maize hybrids from the Latin America breeding program, application instructions and other relevant material is available in the CIMMYT Maize Product Catalog and in the links provided below.
In an op-ed on Newsweek, CIMMYT director general Bram Govaerts wrote argues the best protection is actually reducing food system risks by building food system resilience against shocks. He highlighted how previous investments in agricultural research and development generated evidence-based strategies that mitigate global food price crisis.
Several recent studies document the long-term health and economic benefits from the “Green Revolution” — the widespread adoption of high-yielding staple crop varieties during the last half of the 20th century — and argue for continued investment in the development and use of such varieties.
“Our estimates provide compelling evidence that the health benefits of broad-based increases in agricultural productivity should not be overlooked,” the authors state. “From a policy perspective, government subsidies for inputs leading to a green revolution as well as investments in extension and R&D programs seem to be important.”

The COVID-19 pandemic exposed the fragility of the global food system and the need to transform it, increasing its environmental and economic resilience to withstand future threats, and underpinning healthier diets. The studies suggest that improved versions of cereal crops such as rice, wheat, and maize can play a key role.
“Our work speaks to the importance of supporting innovation and technology adoption in agriculture as a means of fostering economic development, improved health, and poverty reduction, said author Jan von der Goltz. “It also suggests that it is reasonable to view with some alarm the steady decline in funding for cereal crop improvement over the last few decades in sub-Saharan Africa, the continent with least diffusion of modern varieties.”
Likewise, a study co-authored by Prashant Bharadwaj of the University of California, San Diego, concluded that farmer adoption of high-yielding crop varieties (HYVs) in India reduced infant mortality dramatically across the country. Between 1960 and 2000, infant deaths dropped from 163.8 to 66.6 per 1,000 live births, and this occurred during the decades of India’s wheat productivity leap from 0.86 to 2.79 tons per hectare, as a result of HYV adoption and improved farming practices.
“What both of these papers do is to carefully establish a causal estimate of how HYVs affect infant mortality, by only comparing children born in the same location at different points in time, when HYV use was different, and by checking that mortality before arrival of HYVs was trending similarly in places that would receive different amount of HYVs,” Bharadwaj said.
“In the absence of a randomized control trial, these econometric techniques produce the best causal estimate of a phenomenon as important as the spread of HYVs during and after the Green Revolution,” he added. These thoughts were echoed by University of California San Diego professor Gordon McCord, a co-author of the global study.
Recent studies indicate that the Green Revolution also had long-term economic impacts, which also affected health outcomes.
In a 2021 update to the 2018 paper “Two Blades of Grass: The Impact of the Green Revolution,” Douglas Gollin, Professor of Development Economics at Oxford University and co-authors found that, in 90 countries where high-yielding varieties were adopted between 1965 and 2010, food crop yields increased by 44% and that, had this adoption not occurred, GDP per capita in the developing world could be half of what it is today.
Even a 10-year delay of the Green Revolution would, in 2010, have cost 17% of GDP per capita in the developing world, with a cumulative GDP loss of $83 trillion, equivalent to one year of current global GDP.
These GDP and health impacts were boosted by a related reduction in population growth. By observing causal inference at country, regional and developing world levels, and using a novel long-term impact assessment method, the study authors detected a trend: as living standards improved for rural families, they generally wanted to invest more in their children and have fewer.
“Our estimates suggest that the world would have contained more than 200 million additional people in 2010, if the onset of the Green Revolution had been delayed for ten years,” Gollin and his co-authors stated. This lower population growth seems to have increased the relative size of the working age population, which furthered GDP growth.

A long-term investment in system transformation
It takes time from the point of an intervention to when broad health impacts can be observed in the population, the authors note. For example, although the development of modern high-yielding varieties began in the 1950s and 60s, the rate of adoption did not speed up until the 1980s, 1990s, and even into the 2000s, with evidence from sub-Saharan Africa showing that variety adoption has increased by as much in the 2000s as in the four preceding decades.
In addition, any nutrition and food security strategy which aims to reach the second Sustainable Development Goal of feeding 9 billion by 2050 must incorporate wider system transformation solutions, such as zero-emissions agriculture, affordable, diverse diets and increased land conservation.
As Gollin explained, “The Green Revolution taught us that we need to approach productivity increases, especially in staple crop yields, differently. The challenge now is more complex: we need to get the same productivity increases, with fewer inputs and resources, more environmental awareness, and in larger quantities for more people.”
In part, this means increasing productivity on existing agricultural land with positive environmental and social impacts, according to Bram Govaerts, director general of the International Maize and Wheat Improvement Center (CIMMYT).
“Breeding and sharing more productive, hardy crop varieties is as important as ever,” Govaerts said, “but also engaging farmers — in our case, smallholders — in shared research and innovation efforts to bridge yield gaps, build climate-resilient farming systems, and open access to better nutrition and market opportunities.”

On December 3, 2021, the International Maize and Wheat Improvement Center (CIMMYT) and its partners inaugurated a state-of-the-art maize doubled haploid (DH) facility in Kunigal, in India’s Karnataka state. The facility was established by CIMMYT in partnership with the University of Agricultural Sciences, Bangalore (UAS Bangalore), with financial support from the CGIAR Research Program on Maize (MAIZE).
It is the first public sector facility of its kind in Asia, fulfilling a very important need for maize breeding programs in the region. The facility, operated by CIMMYT, will provide DH production services for CIMMYT’s and UAS Bangalore’s breeding programs, as well as for national agricultural research institutions and small- and medium-sized seed companies engaged in maize breeding across tropical Asia. This is expected to result in accelerated development and deployment of a greater number of elite, climate-resilient and nutritionally-enriched maize hybrids in tropical Asia.
DH technology has the potential to enhance genetic gains and breeding efficiency, especially in combination with other modern tools and technologies, such as molecular markers and genomic selection. The facility occupies 12 acres of land at the Agricultural Research Station in Kunigal, in southwestern India. It is expected to produce at least 25,000-30,000 maize DH lines per year.

Fast-track maize breeding in Asia
R.S. Paroda, who is a Padma Bhushan awardee in India and the chairman of the Trust for Advancement of Agricultural Sciences (TAAS) in New Delhi, thanked CIMMYT for its role in developing the facility. “The maize DH facility will revolutionize hybrid maize programs in both the public and private sectors in Asia, enabling fast-tracked development of climate-resilient and genetically diverse maize hybrids suitable for the rainfed maize-growing areas.”
S. Rajendra Prasad, vice chancellor of UAS Bangalore, appreciated the partnership between his institution and CIMMYT. “The facility will create opportunities to modernize maize breeding programs in India, besides serving as an educational and training hub for young students at the University,” he said. Members of UAS Bangalore Board of Management also participated in the formal opening of the facility.
B.M. Prasanna, director of CIMMYT’s Global Maize Program and the CGIAR Research Program on Maize (MAIZE), spearheaded the process of establishing this important breeding facility. “Along with similar maize DH facilities in Mexico and Kenya, which respectively serve Latin America and Africa, this third facility for Asia rounds up CIMMYT’s commitment to strengthen tropical maize breeding programs across the globe,” he explained.
Bram Govaerts, CIMMYT’s director general, participated through a recorded video message.
Attending the ceremony were also 150 post-graduate students, faculty from UAS Bangalore, researchers from UAS Raichur and the Indian Institute of Maize Research, CIMMYT maize scientists, and private-sector members of the International Maize Improvement Consortium for Asia (IMIC-Asia).

Collaboration networks
A technical workshop titled “Transforming India’s Agriculture and Modernizing Maize Breeding Programs” was held the same day. The workshop featured talks by Paroda on the role of youth in Indian agriculture, Prasanna on modernizing maize breeding and enhancing genetic gain, CIMMYT scientist Vijay Chaikam on maize doubled haploid technology, and CIMMYT breeder Sudha Nair on genomic technologies for maize improvement.
IMIC-Asia held a General Body Meeting soon after the technical workshop, at which B.S. Vivek, maize breeder at CIMMYT, introduced the framework for the third phase of IMIC-Asia. Participants included representatives of the Indian Institute of Maize Research, the All-India Coordinated Maize Improvement Program, and private seed companies with membership in the consortium. Meeting participants expressed a keen interest in utilizing the new doubled haploid facility’s services.

The Association of Mexican Seed Producers (Asociación Mexicana de Semilleros, A.C., or AMSAC) gave the International Maize and Wheat Improvement Center (CIMMYT) its annual Cesár Garza Award for work by MasAgro (Crops for Mexico), a project that develops and spreads high-yielding, climate resilient maize and improved farming practices in Mexico. MasAgro is operated by CIMMYT and Mexico’s Secretariat of Agriculture and Rural Development (SADER).
“We unanimously selected CIMMYT for having established an effective and inclusive network of some 100 Mexican testing sites to generate and spread hybrid seed adapted to the country’s diverse agro-ecologies,” said José Luis Gastelum Careaga, president of the governing council of AMSAC, a group of more than 70 seed companies.
The award ceremony took place in Playa del Carmen, in Mexico’s Quintano Roo state, on November 4, 2021.
CIMMYT breeding research is behind the development of 70 new maize hybrids released in Mexico by dozens of small- and intermediate-scale seed companies, helping to double the maize yields of farmers who adopt them, according to Bram Govaerts, CIMMYT director general and leader of the Center’s work in MasAgro.
“AMSAC’s recognition comes at a crucial time, when public support for crop breeding, seed systems, and capacity building are more urgent than ever in the face of climate change and increased, pandemic-related food insecurity,” Govaerts said. “We’ll leverage this prestigious award and our strong partnership with AMSAC members to move toward an improved and more widespread version of MasAgro’s integrated approach for transforming Mexico’s cereal crop farming systems.”
Propelling public-private partnerships

Taking advantage of CIMMYT training and breeding lines, Mexican seed producers working with MasAgro have boosted their maize seed sales 33% — or 4.6% yearly — during 2011–20, Govaerts said.
This and the recent award illustrate CIMMYT’s success at sharing improved maize through powerful, decades-long partnerships with public and private entities. Small- and medium-scale seed companies have benefitted from access to CIMMYT breeding lines, technical support, business model training, and Center participation in efforts to foster competitive seed markets, according to a recently published book documenting 50 years of maize research by CIMMYT and the International Institute of Tropical Agriculture (IITA). Both centers are members of CGIAR, the world’s largest global agricultural innovation network.
“The increased number and market share of [small- and medium-scale] maize seed companies in Mexico and sub-Saharan Africa in recent years are strongly linked to the availability of stable, stress tolerant inbreds from CGIAR programs,” the book’s executive summary states. “The annual production … of over 130,000 tons of seed of CGIAR-derived stress-tolerant hybrids in Africa by [small- and medium-scale enterprises] … has addressed an important gap in seed markets not being met by multi-national companies.”
In 2015 more than a third of the area in sub-Saharan Africa was sown to new varieties and hybrids derived from CIMMYT and IITA breeding research, and adoption has accelerated since then, generating from $0.66 to 1.05 billion each year in economic benefits, according to a 2021 study.
As part of CIMMYT partnerships with large, multi-national seed companies, the Center has obtained royalty-free licenses to use proprietary technology and maize hybrids in specific areas of Africa, focusing on small-scale farmers. These partnerships, as well as similar agreements with advanced public research institutes, have fostered more widespread application for tropical maize of tools such as genomic selection, database software, and doubled haploids.
In Asia, building on collaborations from as far back as the 1960s, CIMMYT launched a maize improvement consortium in 2010 involving 25 mostly small- and medium-scale seed companies. For a modest annual fee to fund consortium management, members have access to early- and advanced-generation CIMMYT inbred lines and trait donors, as well as support services for hybrid development. This model has subsequently been copied in Mexico and in eastern and southern Africa (17 companies).
“CIMMYT science and support for maize and wheat farming systems span more than six decades and have brought impressive, well documented impacts in improved harvests and food security for those who grow and consume these globally-critical staple crops,” Govaerts said. “On behalf of the Center, I would like to recognize and thank those who fund our work, and especially the hundreds of skilled and committed partners without whom our efforts would not be possible.”
For over a decade, the CGIAR Research Programs on Maize (MAIZE) and Wheat (WHEAT) have been at the forefront of research-for-development benefiting maize and wheat farmers in the Global South, especially those most vulnerable to the shocks of a changing climate.
From 2012 to 2021, MAIZE has focused on doubling maize productivity and increasing incomes and livelihood opportunities from sustainable maize-based farming systems. Through MAIZE, scientists released over 650 elite, high-yielding maize varieties stacked with climate adaptive, nutrition enhancing, and pest and disease resistant traits.
The WHEAT program has worked to improve sustainable production and incomes for wheat farmers, especially smallholders, through collaboration, cutting-edge science and field-level research. Jointly with partners, WHEAT scientists released 880 high-yielding, disease- and pest-resistant, climate-resilient and nutritious varieties in 59 countries over the life of the program.
To document and share this legacy, the MAIZE and WHEAT websites have been redesigned to highlight the accomplishments of the programs and to capture their impact across the five main CGIAR Impact Areas: nutrition, poverty, gender, climate and the environment.
We invite you to visit these visually rich, sites to view the global impact of MAIZE and WHEAT, and how this essential work will continue in the future.
CIMMYT’s relationship with Mexico is one of a kind: in addition to being the birthplace of the wheat innovations that led to the Green Revolution and the founding of CGIAR, Mexico is also where maize originated thousands of years ago, becoming an emblem of the country’s economy and identity.
Honoring this longstanding connection and celebrating Mexico’s key contribution to global wheat and maize production, Mexico City will host a photo exhibition from December 1, 2021, to January 15, 2022, in the Open Galleries Lateral, located on Paseo de la Reforma, one of city’s most iconic promenades.
Titled “Maize and Wheat Research in Focus: Celebrating a Decade of Research for Sustainable Agricultural Development Under the CGIAR Research Programs on Maize and Wheat,” the exhibition illustrates the impact of MAIZE and WHEAT over the last ten years. The selection of photographs documents the challenges faced by maize and wheat smallholders in different regions, and showcases innovative interventions made by national and regional stakeholders worldwide.
From pathbreaking breeding research on climate-smart varieties to helping farming families raise their incomes, the photos — taken by CGIAR photographers before the COVID-19 pandemic — capture both the breadth of the challenges facing our global agri-food systems and the spirit of innovation and cooperation to meet them head on.
Don’t miss the chance to visit the exhibition if you are in Mexico City!

Three scientists from the International Maize and Wheat Improvement Center (CIMMYT) have been included in the Highly Cited Researchers list for 2021, published by the Web of Science Group.
The list recognizes researchers who demonstrated significant influence in their field, or across fields, through the publication of multiple highly cited papers during the last decade. Their names are drawn from the publications that rank in the top 1% by citations for field and publication year in the Web of Science citation index.
Called a “who’s who” of influential researchers, the list draws on data and analysis performed by bibliometric experts and data scientists at the Institute for Scientific Information at Clarivate, the company which publishes the list.
This year, the three CIMMYT scientists listed are:
The demand for maize for poultry feed in Nepal has increased dramatically over the years. It constitutes about 60% of the poultry feed and is considered as the principal energy source used in poultry diets. About 70% of the total crop required by the feed industry is imported and such dependence on import could jeopardize its sustainability if any political, natural or health related crisis disrupts the supply chain. In addition to maize, the industry also imports synthetic amino acid to meet the requirements of poultry production since the regular maize grain used by the feed industry is deficient in essential amino acids that helps form proteins.
A recent assessment conducted by the International Maize and Wheat Improvement Center (CIMMYT) in Nepal highlights the prospects of using Quality Protein Maize (QPM) to mitigate protein deficiency found in regular maize. The authors suggest that the poultry feed industry can minimize the average feed cost by 1.5% by substituting regular maize with QPM. This would translate to a daily cost-saving of about US$26,000 for the industry. If this cost saving is shared across the value chain actors including farmers for domestic production of QPM and other biofortified maize vis a vis regular maize, then the dependency on imported maize can be significantly reduced.
The article published in the journal of International Food and Agribusiness Marketing, estimated least cost diet formulations for broilers and layers of different age groups, and the potential gains to be garnered by the maize seed and grain value chain actors in Nepal.
According to the study, a ton of feed produced using QPM reduces feed cost by at least US$7.1 for the broilers and by US$4.71 for layers. As a result, Nepal’s poultry feed industry can pay a maximum of 4% price premium with the cost saving for QPM.
“Considering the cost reduction potential QPM brings over regular maize, it can be a win-win situation for the poultry feed sector and maize value chain actors if they are strongly linked and operated in an integrated fashion,” explain the authors.
“By building awareness on the cost benefits, the feed industry exhibited a positive perception during the study period to use QPM for feed. Linking the seed companies with the feed mills is essential to leverage the benefits of the product.”
To promote and expand QPM production in Nepal, the authors also recommend provision of seed and fertilizer subsidies by the Government of Nepal to feed producers and cooperatives ensuring a continuous supply of the product to meet the demand.
The GoN has released two varieties of QPM maize but due to lack of effective seed production, extension and marketing programs, the potential of QPM maize remains unutilized. However, the authors firmly believe that appropriate policy focus on QPM seed production and grain marketing including premium price for QPM growers, can change the scenario where the demand for maize for feed industry can be gradually managed with domestic production.
The current focus in nutritional circles on micronutrient malnutrition and unhealthy eating habits has raised questions about continuing to invest in research on energy-rich cereal crops and related farming systems.
In this new paper in the International Journal of Agricultural Sustainability, development scientists make the case that cereal foods are an important vehicle for enhanced nutrition – with additional improvement possible through plant breeding and interventions in processing, manufacturing and distribution. It also explains cereals are a rich source of both dietary fiber and a range of bioactive food components that are essential for good health and well-being.
The authors suggest a balanced, integrated research approach to support the sustainable production of both nutrient-rich crops and the basic cereals used in humanity’s most widely consumed and popular foods.

High-level representatives of the Carlos Slim Foundation and Mexico’s National Agriculture Council (CNA) visited the global headquarters of the International Maize and Wheat Improvement Center (CIMMYT) outside Mexico City on October 18, 2021, to learn about innovative research to promote sustainable production systems in Mexico and the world.
Carlos Slim Foundation and CNA representatives agreed that public and private sectors, civil society and international research organizations like CIMMYT must collaborate to address the challenges related to climate change, forced migration and rural insecurity.
“It is necessary to give more visibility to and make use of CIMMYT’s world-class laboratories and research fields, to enhance their impact on sustainable development and the 2030 agenda,” said Juan Cortina Gallardo, president of the CNA.
The tour included a visit to CIMMYT’s germplasm bank, where the world’s largest collections of maize and wheat biodiversity are conserved. Visitors also toured the laboratories, greenhouses and experimental fields where cutting-edge science is applied to improve yield potential, adaptability to climate change, resistance to pests and diseases, and nutritional and processing quality of maize and wheat.

From Mexico to the world
“CIMMYT implements Crops for Mexico, a research and capacity building project building on the successes and lessons learned from MasAgro, where smallholder farmers increase their productivity to expand their market opportunities and can, for example, join the supply chain of large companies as providers and contribute to social development of Mexican farming,” Cortina Gallardo said.
CIMMYT carries out more than 150 integrated development projects related to maize and wheat systems in 50 countries. They are all supported by first-class research infrastructure in CIMMYT’s global headquarters, funded by the Carlos Slim Foundation.
“Our goal is to put CIMMYT’s laboratories, greenhouses and experimental fields at the service of farmers and both public and private sectors as needed,” said Bram Govaerts, director general of CIMMYT. “Accelerating the development of sustainable agricultural practices and more nutritious and resilient varieties contributes to transforming agricultural systems around the world, strengthening global food security and reducing the impact of agriculture on climate change.”
CIMMYT’s maize breeding focuses on developing elite maize hybrids suited to various agro-ecological zones across Africa, Asia and Latin America.
Public and private institutions may apply for permission to register and subsequently commercialize CIMMYT maize varieties in specific countries within the framework of the applicable laws, rules and regulations, and policies and procedures as described here: Acquisition and use of CIMMYT maize hybrids and OPVs for commercialization.

Launched in May 2018, the International Maize Improvement Consortium for Africa (IMIC‐Africa) is a public-private partnership designed to strengthen maize breeding programs in Africa, and thereby improve African farmers’ access to high-quality, affordable, high-yielding and locally-adapted maize seed.
Any organization engaged in maize breeding for the African market is welcome to join the consortium, including national agricultural research institutions; small, medium and large maize seed companies; and international agricultural research organizations. Consortium members will have access to early-generation maize breeding material, an expansive hybrid evaluation network for robust evaluation of their products on various traits and across diverse agroecologies, training and capacity-development opportunities, and value-added research services offered at preferential rates.
The Consortium’s goal is to enhance the capacity of African maize breeding programs from public and private sectors to develop elite maize hybrids with client-preferred traits — including abiotic stress resilience, disease and insect pest resistance, and high yield potential — for the ultimate benefit of farming communities across Africa.
Objectives:
Providing members with access to CIMMYT’s early- and advanced-generation maize lines (breeding materials under development) to strengthen and diversify the germplasm used in their own breeding programs;
Allowing members to test their own pre-commercial maize hybrids in CIMMYT-led multi-location trials;
Improving members’ access to research services that improve the efficiency and effectiveness of their own breeding programs;
Facilitating participation by members’ staff in annual training courses.
The International Maize Improvement Consortium for Asia (IMIC-Asia) is a public-private partnership formed by CIMMYT to develop and share improved maize varieties for targeted impacts in Asia.
Established in 2010, IMIC-Asia has developed and distributed thousands of improved inbred lines developed by CIMMYT to members for use in new inbred line development or in heterotic hybrid combinations of the partners. Molecular breeding is one of the key strategies used to enhance genetic gains and accelerate the pace of product development, helping researchers understand the genetics of complex traits, like heat stress and waterlogging tolerance.
IMIC-Asia’s activities also include training on maize breeding, phenotyping for abiotic stresses, statistical and genomic analysis data management imparted through this consortium, and evaluation of pre-release hybrid combinations of partners.
Consortium members also benefit from a strong collaborative testing network for identifying best-bet pre-release products, which now serves as a precursor for such products to be further evaluated at the national or state level as a part of the varietal release process.
