Theme: Nutrition, health and food security

As staple foods, maize and wheat provide vital nutrients and health benefits, making up close to two-thirds of the world’s food energy intake, and contributing 55 to 70 percent of the total calories in the diets of people living in developing countries, according to the U.N. Food and Agriculture Organization. CIMMYT scientists tackle food insecurity through improved nutrient-rich, high-yielding varieties and sustainable agronomic practices, ensuring that those who most depend on agriculture have enough to make a living and feed their families. The U.N. projects that the global population will increase to more than 9 billion people by 2050, which means that the successes and failures of wheat and maize farmers will continue to have a crucial impact on food security. Findings by the Intergovernmental Panel on Climate Change, which show heat waves could occur more often and mean global surface temperatures could rise by up to 5 degrees Celsius throughout the century, indicate that increasing yield alone will be insufficient to meet future demand for food.

Achieving widespread food and nutritional security for the world’s poorest people is more complex than simply boosting production. Biofortification of maize and wheat helps increase the vitamins and minerals in these key crops. CIMMYT helps families grow and eat provitamin A enriched maize, zinc-enhanced maize and wheat varieties, and quality protein maize. CIMMYT also works on improving food health and safety, by reducing mycotoxin levels in the global food chain. Mycotoxins are produced by fungi that colonize in food crops, and cause health problems or even death in humans or animals. Worldwide, CIMMYT helps train food processors to reduce fungal contamination in maize, and promotes affordable technologies and training to detect mycotoxins and reduce exposure.

Jamal conquered his dreams through maize farming

When we talk about the impact of agricultural research we often rely on numerical metrics: percent increase in yield, percent decrease in crop loss, adoption rates, etcetera. For farmers on the ground, however, the impact can be much harder to boil down to a few numbers. Hiding behind every statistical table are real stories of dreams dashed or fulfilled, of everyday people trying to survive and flourish.

A new educational video powerfully dramatizes this point through the story of Jamal Mia and his daughter Rupa. Jamal’s dreams to own a house and see Rupa enroll in college are threatened when his maize crop is attacked by fall armyworm. An encounter with an agricultural extension officer puts Jamal on track to tackle the infestation, save his crop and secure his family’s wellbeing.

The video was developed by CIMMYT with support from Bangladesh’s Department of Agricultural Extension and the Bangladesh Wheat and Maize Research Institute (BWMRI), as part of a project titled “Fighting back against fall armyworm in Bangladesh.” Supported by USAID’s Feed the Future Initiative and Michigan State University, this CIMMYT-led project works in synergy with the Cereal Systems Initiative for South Asia (CSISA) and with national partners to mitigate the impact of this invasive pest on smallholder farmers’ livelihoods.

The video was filmed in Dinajpur district, Bangladesh, and is available in Bangla with English captions.

Scientists find genomic regions associated with wheat blast resistance in CIMMYT nurseries

In an article published in Nature Scientific Reports, a team of scientists led by wheat breeder Philomin Juliana from the International Wheat and Maize Improvement Center (CIMMYT) conducted a large genome-wide association study to look for genomic regions that could also be associated with resistance to wheat blast.

Juliana and fellow scientists found 36 significant markers on chromosome 2AS, 3BL, 4AL and 7BL that appeared to be consistently associated with blast resistance across different environments. Among these, 20 markers were found to be in the position of the 2NS translocation, a chromosomal segment transferred to wheat from a wild relative, Aegilops ventricosa, that has very strong and effective resistance to wheat blast.

The team also gained excellent insights into the blast resistance of the globally-distributed CIMMYT germplasm by genomic fingerprinting a panel over 4,000 wheat lines for the presence of the 2NS translocation, and found that it was present in 94.1% of lines from International Bread Wheat Screening Nurseries (IBWSNs) and 93.7% of lines from Semi-Arid Wheat Screening Nurseries (SAWSNs). Although it is reassuring that such a high percentage of CIMMYT wheat lines already have the 2NS translocation and implied blast resistance, finding other novel resistance genes will be instrumental in building widespread, global resilience to wheat blast outbreaks in the long-term.

The researchers used data collected over the last two years from CIMMYT’s IBWSNs and SAWSNs by collaborators at the Bangladesh Wheat and Maize Research Institute (BWMRI) and Bolivia’s Instituto Nacional de InnovaciĂłn Agropecuaria y Forestal (INIAF).

Devastating fungal disease

Wheat blast, caused by the fungus Magnaporthe oryzae pathotype Triticum, was first identified in 1985 in South America, but has been seen in Bangladesh in recent years. The expansion of the disease is a great concern for regions of similar environmental conditions in South Asia, and other regions globally.

Although management of the disease using fungicide is possible, it is not completely effective for multiple reasons, including inefficiency during high disease pressure, resistance of the fungal populations to some classes of fungicides, and the affordability of fungicide to resource-poor farmers. Scientists see the development and deployment of wheat with genetic resistance to blast as the most sustainable and farmer-friendly approach to preventing devastating outbreaks around the world.

This work was made possible by the generous support of the Delivering Genetic Gains in Wheat (DGGW) project funded by the Bill & Melinda Gates Foundation, the U.K. Foreign, Commonwealth & Development Office (FCDO) and managed by Cornell University, the U.S. Agency for International Development’s Feed the Future initiative, the CGIAR Research Program on Wheat (WHEAT), the Indian Council of Agricultural Research (ICAR), The Swedish Research Council (VetenskapsrĂ„d), and the Australian Centre for International Agricultural Research (ACIAR).

Starting with Seeds

Seeds are the start and the first step in a solution for global hunger.

B.M. Prasanna, director of the Global Maize Program and of the CGIAR Research program on Maize at the International Maize and Wheat Improvement Center (CIMMYT), says smallholder farms in sub-Saharan Africa make up 80% of all farms there, and contribute significantly to food production in the region.

“Over the past 15 years, CIMMYT and partners in sub-Saharan Africa have been able to intensively work with seed companies to invest in deployment of climate-resilient and nutritionally enriched maize seed, and generate demand for such products,” Prasanna says.

Efforts in controlling maize disease boosting steady supply of certified seeds

Efforts towards managing the Maize Lethal Necrosis (MLN), a viral disease affecting maize, have contributed to reducing seed production losses from  33 per cent to 16 per cent in the last four years, bolstering  steady supply of maize seeds in the Eastern African region.

Seed Seekers, Seed Keepers, Seed Growers

Seed banks may be another resource for securing Indigenous seed, although these banks have other missions as well. The International Maize and Wheat Improvement Center (CIMMYT), maintains seed banks and programs to preserve seeds native to specific regions. The group also leads the CGIAR Research Programs on Maize and Wheat and the Excellence in Breeding Platform to characterize genetic diversity so it can be used in conventional breeding programs to develop wheat and maize varieties that can address climate change, pest and disease resistance and yield to help manage food security.

“About 100 seed banks exist worldwide with seed used for cultural or heritage purposes and for production. CIMMYT has varieties that have been cultivated, conserved and cherished as grain and food crops for thousands of years,” says Tom Payne, head of the non-profit organization’s wheat germplasm collections and International Wheat Improvement Network. “Our seed bank conserves varieties that can be a source for finding old genes that will solve new problems. We have to have that diversity to address changing production environments.”

Tangible agricultural solutions shine at first online AGRF

For ten years now, the African Green Revolution Forum (AGRF) has been an unmissable event. Every September, the premier forum for African agriculture has brought people together to share experiences about transforming agriculture, raising productivity for farmers and increasing incomes.

The theme of the 2020 summit — Feed the Cities, Grow the Continent: Leveraging Urban Food Markets to Achieve Sustainable Food Systems in Africa — was a call to action to rethink our food systems to make them more resilient and deliver better nourishment and prosperity for all.

This year, the summit went virtual. Delegates could not mingle, visit booths and network over lunch, but attendance reached new heights. Over 10,400 delegates from 113 countries participated in this edition of the AGRF, compared to 2,300 delegates last year.

As in the previous years, CGIAR centers, including the International Maize and Wheat Improvement Center (CIMMYT), maintained an active presence among speakers and attendees.

With over 50 projects and hundreds of staff based across nine countries, Africa holds a significant position in CIMMYT’s research agenda. CIMMYT’s work in Africa helps farmers access new maize and wheat system-based technologies, information and markets, raising incomes and enhancing crop resilience to drought and climate change. CIMMYT sets priorities in consultation with ministries of agriculture, seed companies, farming communities and other stakeholders in the maize and wheat value chains.

Striving for excellence

CGIAR leveraged AGRF 2020’s highly diversified and international audience to launch the Excellence in Agronomy 2030 initiative (EiA 2030) on September 7, 2020. EiA’s impressive group of experts plans to hit the ground running in 2020 and work toward speeding up progress in tailoring and delivering nutrients and other agronomic solutions to smallholder farmers in Africa and other regions.

“Across agricultural production systems, low crop yields and inadequate incomes from agriculture are the rule rather than the exception,” said Martin Kropff, Director General of CIMMYT and Chair of One CGIAR Transition Advisory Group (TAG) 2 on Research. “At the same time, the ‘asks’ of agriculture have evolved beyond food security. They now include a broader range of Sustainable Development Goals, such as sustainable land management, climate change mitigation, provision of heathy diets, and inclusive economic growth. None of these goals will be achieved without the large-scale adoption of improved and adapted agronomic practices. To this end, we have initiated the creation of a CGIAR-wide EiA 2030 initiative aiming at reducing yield and efficiency gaps for major crops at scale.”

EiA 2030 is funded by the Bill & Melinda Gates Foundation, supported by the Big Data Platform and co-created by AfricaRice, CIAT, CIMMYT, CIP, ICARDA, ICRAF, ICRISAT, IITA and IRRI.

Scaling agriculture beyond numbers

On September 7, 2020, a group of experts, including Lennart Woltering, Scaling Catalyst at CIMMYT and chair of the Agriculture and Rural Development (ARD) working group of the Community of Practice on Scaling, gathered to explore how organizations are supporting scaling food systems in a post-COVID-19 world.

As Martin Kropff mentioned in a video address, One CGIAR aims to deliver on its commitments by building on its experience with pioneering integrated development projects, such as CSISA, CIALCA and AVISA. “One CGIAR plans to be actively involved and help partners to scale by delivering on five One CGIAR impact areas at the regional level. How? By taking integrated regional programs from strategic planning to tactical implementation in three steps: strategic multi-stakeholder demand-driven planning process, tactical plan development based on the integration of production and demand, and implementation of multi-stakeholder innovation hubs. An integrated regional approach will deliver at scale,” Kropff said.

“CIMMYT has developed different scenarios regarding what agri-food systems will look like in 2025 with the COVID-19 shock. Whatever may unfold, integrated systems are key,” highlighted Bram Govaerts, Director of the Integrated Development Program and one of CIMMYT’s interim Deputy Directors General for Research, during the session.

“Diversity and proactive mindsets present at the #AGRF2020 High-Level Ministerial Roundtable. An example of how we can shape the future, listening to what’s needed, investing in agriculture and making resilient food systems to resist the impact of #COVID19 #AgricultureContinues,” tweeted Bram Govaerts (first row, second from left) along with a screenshot of his Zoom meeting screen.

Putting healthy diets on the roundtable

Later in the week, CIMMYT experts took part in two key events for the development of Africa’s agriculture. Govaerts stepped in for Kropff during the High-Level Ministerial Roundtable, where regional leaders and partners discussed reaching agricultural self-sufficiency to increase the region’s resilience toward shocks such as the ongoing pandemic.

At the Advancing Gender and Nutrition policy forum, Natalia Palacios, Maize Quality Specialist, spoke about engaging nutritionally vulnerable urban consumers. Palacios echoed the other speakers’ calls for transforming agri-food systems and pointed out that cereals and effective public-private partnerships are the backbone of nutritionally vulnerable and poor urban customers’ diets.

According to the Food and Agriculture Organization of the UN, in 30 years, the population of Africa is projected to double to a number as high as 2.7 billion, from 1.34 billion in 2020. Considering only the projected population, by 2050 Africa will have to supply 112.4 to 133.1 million tons of wheat and 106.5 to 126.1 million tons of maize to ensure food security of the burgeoning population. “We are living in a very challenging time because we need to provide affordable, nutritious diets — within planetary boundaries,” Palacios said.

The search is on for nontoxic solutions to fall armyworm across Africa

Last year, AgBiTech launched a partnership between the United States Agency for International Development, FAO, International Maize and Wheat Improvement Center, and Centre for Agriculture and Bioscience International in South Sudan to train farmers in using Fawlingen. These farmers have shown a 63% increase in yield compared to untreated plots and the pilot is being scaled to reach thousands of farmers this season.

Wheat blast has made the intercontinental jump to Africa

Wheat blast, a fast-acting and devastating fungal disease, has been reported for the first time on the African continent. In an article published in the scientific journal PLoS One, a team of scientists confirmed that symptoms of wheat blast first appeared in Zambia during the 2018 rainy season, in experimental plots and small-scale farms in the Mpika district, Muchinga province.

Researchers from the International Maize and Wheat Improvement Center (CIMMYT), the US Department of Agriculture – Foreign Disease Weed Science Research Unit (USDA-ARS) and the Zambian Agricultural Research Institute (ZARI) participated in this study.

Wheat blast poses a serious threat to rain-fed wheat production in Zambia and raises the alarm for surrounding regions and countries on the African continent with similar environmental conditions. Worldwide, 2.5 billion consumers depend on wheat as a staple food and, in recent years, several African countries have been actively working towards reducing dependence on wheat imports.

“This presents yet another challenging biotic constraint to rain-fed wheat production in Zambia,” said Batiseba Tembo, wheat breeder at ZARI and lead scientist on the study.

A difficult diagnosis

“The first occurrence of the disease was very distressing. This happened at the spike stage, and caused significant losses,” Tembo said. “Nothing of this nature has happened before in Zambia.”

Researchers were initially confused when symptoms of the disease were first reported in the fields of Mpika. Zambia has unique agro-climatic conditions, particularly in the rainfed wheat production system, and diseases such as spot blotch and Fusarium head blight are common.

“The crop had silvery white spikes and a green canopy, resulting in shriveled grains or no grains at all
 Within the span of seven days, a whole field can be attacked,” Tembo explained. Samples were collected and analyzed in the ZARI laboratory, and suspicions grew among researchers that this may be a new disease entirely.

Tembo participated in the Basic Wheat Improvement Course at CIMMYT’s global headquarters in Mexico, where she discussed the new disease with Pawan Singh, head of Wheat Pathology at CIMMYT. Singh worked with Tembo to provide guidance and the molecular markers needed for the sample analysis in Zambia, and coordinated the analysis of the wheat disease samples at the USDA-ARS facility in Fort Detrick, Maryland, United States.

All experiments confirmed the presence of the fungus Magnaporthe oryzae pathotype Triticum (MoT), which causes the disease.

“This is a disaster which needs immediate attention,” Tembo said. “Otherwise, wheat blast has the potential to marginalize the growth of rain-fed wheat production in Zambia and may threaten wheat production in neighboring countries as well.”

Wheat blast spreads through infected seeds and crop residues, as well as by spores that can travel long distances in the air. The spread of blast within Zambia is indicated by both mechanisms of expansion.

A cause for innovation and collaboration

CIMMYT and the CGIAR Research Program on Wheat (WHEAT) are taking action on several fronts to combat wheat blast. Trainings and international courses invite participants to gain new technical skills and knowledge in blast diagnostics, treatment and mitigation strategies. WHEAT scientists and partners are also studying the genetic factors that increase resistance to the disease and developing early warning systems.

“A set of research outcomes, including the development of resistant varieties, identification of effective fungicides, agronomic measures, and new findings in the epidemiology of disease development will be helpful in mitigating wheat blast in Zambia,” Singh said.

“It is imperative that the regional and global scientific communities join hands to determine effective measures to halt further spread of this worrisome disease in Zambia and beyond,” Tembo expressed.

Partners in nutrition

It is no secret that Africa is urbanizing at breakneck speed. Consider Lagos. In 1950 the Nigerian city boasted a population of a few hundred thousand. Today that number has soared to around 14 million. It is estimated that by 2025 half of Africa’s population will live in urban areas.

This demographic transformation has had dramatic consequences for human health and nutrition. Urban dwellers are far more likely to rely on cheap highly-processed foods, which are shelf-stable but poor on nutrients.

These statistics, presented by moderator Betty Kibaara, Director of the Food Initiative at The Rockefeller Foundation, framed the 2020 African Green Revolution Forum’s policy symposium on “Advancing Gender and Nutrition.” The forum comprised two tracks. One focused on addressing the needs of nutritionally vulnerable urban consumers, particularly women; the other on gender-based financing in the African agri-food system

Speaking in the first track, Natalia Palacios, maize quality specialist at the International Maize and Wheat Improvement Center (CIMMYT), underlined the enormity of the challenge. “We need to provide affordable, nutritious diets … within planetary boundaries,” she said.

Many of the panelists pointed out further dimensions of the challenge — from evidence deficits around the continent’s urban populations to the amplifying effects of the COVID-19 crisis. Palacios stressed that the bedrock of any response must be effective partnerships between governments, companies and non-profit actors working in this area.

“The really important thing is to start working together,” she said, “to start developing the strategies together instead of providing things or demanding things.” Speaking to the role of organizations like CIMMYT, Palacios highlighted the need to work closely with the private sector to understand the demand for agricultural raw materials that can be converted into nutritious diets.

Rich nutrition within reach

Palacios’ most recent research efforts focus on precisely this question. She and a team of researchers, including CIMMYT senior scientist Santiago Lopez-Ridaura, explored how various innovations in maize production have improved the macro- and micro-nutrient content of the grain and led to healthier maize-based agri-food systems.

This is significant because for millions of the estimated 2 billion people globally who suffer from “hidden hunger” a more diversified diet rich in costly, perishable, nutrient-dense foods is not economically feasible. In low- and middle-income countries across Africa, Asia and Latin America, it estimated that rice, maize and wheat account for 55 to 70% of calories.

CIMMYT, HarvestPlus and the International Institute of Tropical Agriculture (IITA), together with several stakeholders, have been deeply involved in work to improve the nutritional quality of staple-dependent food systems. In partnership with a broad network of national and private-sector partners, they have released over 60 improved maize and wheat varieties fortified with zinc or provitamin A in 19 countries.

50 years building peace through agriculture

On December 10, 1970, the former chair of the Nobel Committee, Aase Lionaes, called Norman Borlaug to receive the Nobel Peace Prize arguing, “He has given us a well-founded hope, an alternative of peace and of life — the Green Revolution.”

From that moment, Borlaug became known as “the man who saved one billion lives” from famine and as “the father of the Green Revolution.” Borlaug started a pivotal process in the 20th century, characterized by the development of high-yielding new wheat and maize varieties from the International Maize and Wheat Improvement Center (CIMMYT).

“Food is the moral right of all who are born into this world,” Borlaug said during his acceptance speech or Nobel Lecture almost 50 years ago. The scientist, credited for coining the phrase “You can’t build peace on empty stomachs,” became the world’s most acknowledged advocate of the right to food.

The Nobel Peace Center, the government of Mexico — through its Embassy in Oslo, Norway — and CIMMYT remembered Norman Borlaug’s legacy to commemorate the International Day of Peace on September 21. Established in 1981 by the United Nations General Assembly, this day calls to halt all forms of violence for 24 hours and to strengthen the ideals of peace, including Sustainable Development Goal number 2, ‘zero hunger.’

“Dr. Borlaug’s impact is an example of international cooperation for us to learn from and build the future,” said Ulises Canchola GutiĂ©rrez, Mexico’s Ambassador to Norway, in the video Borlaug’s legacy: Agriculture for Peace #PeaceDay 2020.

According to the Nobel Peace Center, “Dr. Norman Borlaug’s work is one of the greatest achievements for humankind.” On a similar note, CIMMYT’s director general, Martin Kropff, noted that “Peace lies in the hands of those who cultivate the land. We can build peace through agriculture.”

CIMMYT carries on Borlaug’s legacy by implementing integrated strategic development projects that aim to transform food production units into sustainable, resilient and healthy agri-food systems. For that reason, CIMMYT issued a call to form an international coalition to tackle the current crisis and avert a new food crisis.

“Norman Borlaug led the charge in the war against hunger more than 50 years ago; let us learn from this experience, let us do it again together by listening to the current crisis and by developing a matching transformative answer to overcome today’s challenges and shortcomings,” said Bram Govaerts, director of CIMMYT’s Integrated Development program and representative for the Americas.

CIMMYT and IITA collaborate to increase adoption of conservation agriculture in southern Africa

The International Institute of Tropical Agriculture (IITA) and the International Maize and Wheat Improvement Center (CIMMYT) recently launched a project that aims to research the drivers and barriers to adoption of conservation agriculture in southern Africa, and to develop strategies for achieving adoption and impact at scale.

The project, Understanding and Enhancing Adoption of Conservation Agriculture in Smallholder Farming Systems of Southern Africa (ACASA), will apply social and scaling science to understand the biophysical, socioeconomic, institutional, and policy drivers and barriers to the adoption of conservation agriculture technologies and practices.

The ACASA project is supported by the Norwegian Agency for Development Cooperation (Norad) and will be implemented in Malawi, Zambia, and Zimbabwe in collaboration with partners and farmers in the region.

The project was officially launched online on September 16, 2020. Zambia’s Minister of Agriculture, Michael Katambo, noted that it is a timely intervention, as the livelihoods and food security of smallholder farmers in southern Africa are increasingly being threatened by climate change and variability, which have led to a steady decline in the production of food staples and an increase in the number of food and nutrition-insecure people.

“It is now clear that current productivity and production levels cannot be expected to meet our requirements for food and nutrition security,” Katambo said in a speech read on his behalf by Moses Mwale, Director of the Department of Agriculture. “Conservation agriculture has a proven potential to increase and stabilize crop yields, and to support sustainable and resilient production systems and rural livelihoods.”

Proven benefits

Conservation agriculture — a farming system that promotes minimum soil disturbance, permanent soil cover and diversification of plant species — can efficiently increase agricultural productivity while reducing land degradation and improving soil health for more productive, profitable, and sustainable farming.

Substantial on-farm evidence has been generated on the agronomic and economic benefits of conservation agriculture, first introduced in the 1970s in South Africa. Consequently, donors and governments have made a lot of investments to promote and scale conservation agriculture technologies and practices among smallholder farmers in the region. Despite all these efforts, however, the adoption rate among smallholder farmers remains low.

“We should not let the low adoption of conservation agriculture discourage us. Let us use this opportunity to reflect and identify the missing link and come up with more sustainable solutions to the problem,” said the IITA Director for Southern Africa, David Chikoye.

“Although adoption of improved practices by most resource-poor farmers is primarily determined by the potential immediate benefits on crop yields, profits, risk, and livelihoods, there are a number of biophysical, socioeconomic, institutional, and policy factors that promote or hinder adoption of conservation agriculture. The project, therefore, aims to identify the adoption drivers and barriers, and to develop pathways and strategies for inclusive scaling of conservation agriculture practices,” said  Arega Alene, Agricultural Economist at IITA and leader of the ACASA project.

Christian Thierfelder, Principal  Cropping Systems Agronomist at CIMMYT, highlighted some of the bottlenecks for conservation agriculture adoption, noting they were linked more to socioeconomic and cultural factors rather than biophysical. “Conservation agriculture is a viable and proven climate-smart farming system. Future research efforts should go towards understanding farmers’ decision-making and behavioral change, as well as profitability,” Thierfelder said.

Other key partners include the Food and Agriculture Organization of the United Nations (FAO), the African Conservation Tillage Network (ACT) and Centre for Coordination of Agricultural Research and Development for Southern Africa (CCARDESA).

The project launch was attended by policymakers, donors, members of national and regional conservation agriculture taskforces, national and international research institutions, universities, international development institutions, private seed companies, non-governmental organizations, and farmer organizations.

Retrospective quantitative genetic analysis and genomic prediction of global wheat yields

The process for breeding for grain yield in bread wheat at the International Maize and Wheat Improvement Center (CIMMYT) involves three-stage testing at an experimental station in the desert environment of Ciudad Obregón, in Mexico’s Yaqui Valley. Because the conditions in Obregón are extremely favorable, CIMMYT wheat breeders are able to replicate growing environments all over the world and test the yield potential and climate-resilience of wheat varieties for every major global wheat growing area. These replicated test areas in Obregón are known as selection environments (SEs).

This process has its roots in the innovative work of wheat breeder and Nobel Prize winner Norman Borlaug, more than 50 years ago. Wheat scientists at CIMMYT, led by wheat breeder Philomin Juliana, wanted to see if it remained effective.

The scientists conducted a large quantitative genetics study comparing the grain yield performance of lines in the ObregĂłn SEs with that of lines in target growing sites throughout the world. They based their comparison on data from two major wheat trials: the South Asia Bread Wheat Genomic Prediction Yield Trials in India, Pakistan and Bangladesh initiated by the U.S. Agency for International Development Feed the Future initiative and the global testing environments of the Elite Spring Wheat Yield Trials.

The findings, published in Retrospective Quantitative Genetic Analysis and Genomic Prediction of Global Wheat Yields, in Frontiers in Plant Science, found that the ObregĂłn yield testing process in different SEs is very efficient in developing high-yielding and resilient wheat lines for target sites.

The authors found higher average heritabilities, or trait variations due to genetic differences, for grain yield in the ObregĂłn SEs than in the target sites (44.2 and 92.3% higher for the South Asia and global trials, respectively), indicating greater precision in the SE trials than those in the target sites. They also observed significant genetic correlations between one or more SEs in ObregĂłn and all five South Asian sites, as well as with the majority (65.1%) of the Elite Spring Wheat Yield Trial sites. Lastly, they found a high ratio of selection response by selecting for grain yield in the SEs of ObregĂłn than directly in the target sites.

“The results of this study make it evident that the rigorous multi-year yield testing in Obregón environments has helped to develop wheat lines that have wide-adaptability across diverse geographical locations and resilience to environmental variations,” said Philomin Juliana, CIMMYT associate scientist and lead author of the article.

“This is particularly important for smallholder farmers in developing countries growing wheat on less than 2 hectares who cannot afford crop losses due to year-to-year environmental changes.”

In addition to these comparisons, the scientists conducted genomic prediction for grain yield in the target sites, based on the performance of the same lines in the SEs of ObregĂłn. They found high year-to-year variations in grain yield predictabilities, highlighting the importance of multi-environment testing across time and space to stave off the environment-induced uncertainties in wheat yields.

“While our results demonstrate the challenges involved in genomic prediction of grain yield in future unknown environments, it also opens up new horizons for further exciting research on designing genomic selection-driven breeding for wheat grain yield,” said Juliana.

This type of quantitative genetics analysis using multi-year and multi-site grain yield data is one of the first steps to assessing the effectiveness of CIMMYT’s current grain yield testing and making recommendations for improvement—a key objective of the new Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG) project, which aims to accelerate the breeding progress by optimizing current breeding schemes.

This work was made possible by the generous support of the Delivering Genetic Gain in Wheat (DGGW) project funded by the Bill & Melinda Gates Foundation and the UK Foreign, Commonwealth & Development Office (FCDO) and managed by Cornell University; the U.S. Agency for International Development’s Feed the Future initiative; and several collaborating national partners who generated the grain yield data.

CRP Maize Annual Report 2019

The CGIAR Research Program on Maize (MAIZE) is proud to release its 2019 Annual Report.

Around the world, the COVID-19 crisis has emphasized the need to strengthen food systems while improving the food security and livelihoods for the most vulnerable, especially the resource-constrained smallholder farmers.

In 2019 MAIZE and its partners made great advances in the development of improved stress-tolerant maize varieties, continued their battle against fall armyworm in both Africa and Asia, and maintained their focus on sustainable intensification of maize-based cropping systems in sub-Saharan Africa, South Asia and Latin America where maize plays a critical role in food and nutritional security, income and livelihoods of millions of resource-constrained smallholders and consumers. We look forward to continued productive collaborations as we transition with our partners into an integrated, inclusive One CGIAR designed to meet the UN Sustainable Development Goals.

Led by the International Maize and Wheat Improvement Center (CIMMYT), with the International Institute of Tropical Agriculture (IITA) as its main CGIAR Consortium partner, MAIZE focuses on increasing maize production for the 900 million poor consumers for whom maize is a staple food in Africa, South Asia and Latin America.

East Africa partners welcome “new era” in wheat breeding collaboration

Representatives from ministries of agriculture and national agricultural research systems (NARS) in Ethiopia and Kenya recently joined funder representatives and technical experts from the International Maize and Wheat Improvement Center (CIMMYT) to renew a long-standing collaboration under the auspices of an ambitious new project, Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG).

AGG is a 5-year project 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 — two of the world’s most important staple crops. Funded by the Bill & Melinda Gates Foundation, the UK Foreign, Commonwealth, and Development Office (FCDO), the U.S. Agency for International Development (USAID) and the Foundation for Food and Agriculture Research (FFAR), AGG fuses innovative methods that improve breeding efficiency and precision to produce varieties that are climate-resilient, pest- and disease-resistant, highly nutritious, and targeted to farmers’ specific needs.

Ethiopia and Kenya: CIMMYT’s longstanding partners

The inception meeting for the wheat component of AGG in East Africa drew more than 70 stakeholders from Ethiopia and Kenya: the region’s primary target countries for wheat breeding. These two countries have long-standing relationships with CIMMYT that continue to deliver important impacts. Ninety percent of all wheat in Ethiopia is derived from CIMMYT varieties, and CIMMYT is a key supporter of the Ethiopian government’s goal for wheat self-sufficiency. Kenya has worked with CIMMYT for more than 40 years, and hosts the world’s biggest screening facilities for wheat rust diseases, with up to 40,000 accessions tested each year.

AGG builds on these successes and on the foundations built by previous projects, notably Delivering Genetic Gain in Wheat, led by Cornell University. The wheat component of AGG works in parallel with a USAID-funded “zinc mainstreaming” project, meeting the demand for increased nutritional quality as well as yield and resilience.

CIMMYT Director General Martin Kropff gave key remarks at the stakeholder gathering, which took place Thursday, August 20.

“Cooperation between CIMMYT and Ethiopia and Kenya – as in all the countries where CIMMYT works – has had tremendous impact,” he said. “We are proud, not for ourselves, but for the people we work for: the hundreds of millions of poor people and smallholders who rely on wheat and maize for their daily food and incomes.”

“AGG will raise this spirit of global cooperation to a new level.”

AGG Project Leader and CIMMYT Interim Deputy Director General for Research Kevin Pixley introduced the new project as a “unique and important” project that challenges every stakeholder to grow.

“What we would like to achieve is a step change for all of us, he told the stakeholders. “Each of us has the opportunity and the challenge to make a difference and that’s what we’re striving to do.”

Representatives from the agricultural research communities of both target countries emphasized the significance of their long collaboration with CIMMYT and their support for the project.

The Honorable Mandefro Nigussie, Ethiopia’s State Minister of Agriculture, confirmed the ongoing achievements of CIMMYT collaboration in his country.

“Our partnership with CIMMYT [
] has yielded several improved varieties that increased productivity twofold over the last 20 years. He referred to Ethiopia’s campaign to achieve self-sufficiency in wheat. “AGG will make an immense contribution to this. The immediate and intermediate results can help achieve the country’s ambitious targets.”

A holistic and gender-informed approach

Deputy Director of Crops at the Kenya Agriculture and Livestock Organization (KALRO) Felister Makini, representing the KALRO Director General Eliud Kireger, noted the project’s strong emphasis on gender-intentional variety development and gender-informed analysis to ensure female farmers have access to varieties that meet their needs and the information to successfully adopt them.

“The goal of this new project will indeed address KALRO’s objective of enhancing food security and nutrition in Kenya,” she said. “This is because AGG not only brings together wheat breeding and optimization tools and technologies, but also considers gender and socioeconomic insights, which will be pivotal to our envisaged strategy to achieve socioeconomic change.”

Funding partners keen for AGG to address future threats

Before CIMMYT wheat experts took the virtual floor to describe specific workplans and opportunities for partner involvement, a number of funder representatives shared candid and inspiring thoughts.

“We are interested in delivery,” said Alan Tollervey of FCDO, formerly the UK Department for International Development. “That is why we support AGG, because it is about streamlining and modernizing the delivery of products [
] directly relevant to both the immediate demands of poor farmers in developing countries and the global demand for food – but also addressing the future threats that we see coming.”

Hailu Wordofa, Agricultural Technology Specialist at the Bureau for Resilience and Food Security at USAID highlighted the importance of global partnerships for past success and reiterated the ambitious targets of the current project.

“We expect to see genetic gains increase and varieties [
] replaced by farmer-preferred varieties,” he reminded stakeholders. “To make this happen, we expect CIMMYT’s global breeding program to use optimal breeding approaches and develop strong and truly collaborative relationships with NARS partners throughout the entire process.”

“Wheat continues to be a critical staple crop for global food security and supporting CIMMYT’s wheat breeding program remains a high priority for USAID,” he assured the attendees.

He also expressed hope that AGG would collaborate other projects working in parallel, including the Feed the Future Innovation Lab for Applied Wheat Genomics at Kansas State University, and the International Wheat Yield Partnership.

FFAR Scientific Program Director Jeff Rosichan called AGG a “really ambitious project that takes a comprehensive look at the research gaps and challenges and how to translate that research into farmers’ fields.”

Agriculture prevails even under COVID-19

The global COVID-19 pandemic was not ignored as one of several challenges during this time of change and transition.

“As we speak today, despite the challenge that we have with the COVID-19, I am proud to say that work on the nurseries is on-going. We are able to apply [our] skills and deliver world-class science,” said Godwin Macharia, center director at KALRO-Njoro.

“This COVID-19 pandemic has shown us that there is a great need globally to focus on food equity. I think this project allows that to happen,” said Jeff Rosichan from FFAR.

Transformations are also happening at the research organization and funding level. CIMMYT Director General Martin Kropff noted that “demand-driven solutions” for “affordable, efficient and healthy diets produced within planetary boundaries” are an important part of the strategy for One CGIAR, the ongoing transformation of CGIAR, the world’s largest public research network on food systems, of which CIMMYT is a member.

Hans Braun, director of CIMMYT’s Global Wheat Program reminded attendees that, despite these changes, one important fact remains. “The demand for wheat will continue to grow for many years to come, and we must meet it.”
