Millers in Nigeria laud the release to farmers of co-developed, CIMMYT-derived wheat varieties

Nigerian wheat scientists and millers recently recognized and thanked CIMMYT for its contributions to four new wheat varieties released to farmers, citing the varieties’ exceptional performance in field trials and farmers’ fields across national wheat-growing regions.

“The release of these four wheat varieties, uniquely tailored to suit our local conditions, has marked a significant milestone in enhancing food security and farmer livelihoods,” said Ahamed T. Abdullahi, agronomist for wheat value chains at the Flour Milling Association of Nigeria (FMAN), in a recent message to CIMMYT’s Global Wheat program. “The improved characteristics, such as higher yield potential, enhanced disease resistance, and adaptability to local climatic conditions, have significantly boosted wheat productivity. Moreover, the quality profiles of these varieties, as expressed in Nigeria, comply fully with the standards required by the local industry.”

Two of the varieties are bread wheat and yield up to 7 tons of grain per hectare, according to a recent Nigeria Tribune article. The other two are durum wheat, a species grown to make pasta and foods such as couscous and tabbouleh. One of those, given the name LACRIWHIT 14D in Nigeria, was from a CIMMYT wheat line selected for its novel genetic resistance to leaf rust and high-yield potential under irrigated conditions. It was also released in Mexico under the name CIRNO C2008 and is the country’s number-one durum wheat variety, according to Karim Ammar, a wheat breeder at CIMMYT.

“Aside from its high yield potential, it has considerable grain size and an aggressive grain fill that is expressed even under extreme heat,” explained Ammar. “These characteristics have certainly helped its identification as outstanding for Nigerian conditions.”

Writing on behalf of FMAN and the Lake Chad Research Institute (LCRI) of Nigeria’s Federal Ministry of Agriculture and Rural Development, Abdullahi said, “We deeply appreciate the expertise and support provided by CIMMYT throughout the development and release process. Your team’s technical guidance on the access to germplasm has played a crucial role in equipping our farmers and extension agents with the necessary skills and resources for successful wheat cultivation.”

Nigeria has a fast-growing population which, coupled with increasing per capita demand for wheat, has made increasing wheat production a national priority, according to Kevin Pixley, director of the Dryland Crops and Global Wheat programs at CIMMYT.

“Until recently, Nigeria produced only 2% of the wheat it consumes, but potential exists to double the current average yield and expand wheat production by perhaps 10-times its current area,” said Pixley. “New wheat varieties will be essential and must be grown using sustainable production practices that improve farmers’ livelihoods while safeguarding long-term food security and natural resources.”

Abdullahi said the release of the varieties demonstrated the power of collaborative research and highlighted the potential for future collaborations. “We look forward to continued collaborations and success in the pursuit of sustainable food systems.”

CIMMYT Ethiopia signs MoU with key private food processor to bolster durum wheat market

CIMMYT Ethiopia signed a memorandum of understanding (MoU) in November 2023 with the Addis Ababa-based private food processing company Alvima Foods Complex Plc, in an effort to encourage durum wheat production among smallholder farmers and create market linkage in selected woredas of Oromia and Amhara regional states.

The MoU, which is part of CIMMYT Ethiopia’s overall durum wheat project aiming to reinvigorate durum wheat production in the country, was signed by Workneh Rikita, Alvima general manager, and Kindie Tesfaye, CIMMYT Ethiopia’s senior scientist.

CIMMYT Ethiopia signing a memorandum of understanding.

The MoU aims primarily to create market linkage between farmers and manufacturers, in a context of a sharp decrease of durum wheat production. “Prior to the 1980s, 80% of the wheat produced in Ethiopia was durum, but in 2016 our nationwide research on wheat showed that the durum wheat coverage was 5%, which stands in contrast to the country’s effort to industrialize the economy and substitute import goods with local produce”, said Kindie Tesfaye, CIMMYT durum wheat project leader. “We, as CIMMYT, want to encourage farmers to produce good quality durum wheat in quantity, and teach them about contract farming by creating market linkage with produce receivers like Alvima.”

“Cooperation, not business venture”

Established in 2011, Alvima Foods Complex initially centered its operations around importing and exporting agro-food products. In 2017, the company set up a pasta and flour processing factory and contracted 800 farmers to produce durum wheat. “At first, our objective was to produce premium quality pasta, unlike most processing companies in the country which produce pasta from hard wheat or mixed wheat,” said Workneh Rikita, Alvima’s general manager. In the absence of binding rules, the project failed and Alvima resigned to import durum wheat. “The law on contract farming was constituted recently and the difficulties to access foreign currency (therefore to import goods), which led us to turn our attention back to our initial project”, said Workneh Rikita.

Alvima Foods Complex general manager added that his company didn’t sign the agreement as a business venture but as an advantageous cooperation to learn from. He thanked CIMMYT for agreeing to work with his company and expressed his hopes for its success.

The current durum wheat market in Ethiopia is unpredictable as prices are set by the brokers, which heavily disadvantages the growers. The objective of the memorandum of understanding is to address such market challenges faced by farmers, affording them guaranteed market opportunities at a fair price.

As part of the agreement between Alvima Foods Complex and the durum wheat growers in target districts of the Amhara and Oromia regional states, CIMMYT will leverage on its expertise to help the farmers produce more and in good quality. Alvima will access the produce from farmers’ cooperatives directly, without the intervention of middlemen, to guarantee better incomes to producers. Moreover, CIMMYT is training farmers on use of climate information, accessing climate advisories, video-based production trainings, and crop disease management.

“If the farmers get the premium price for their produce, they will be encouraged to continue producing better wheat,” said Kindie Tesfaye. “We want the cooperation to be sustainable and to create direct links between farmers and local food processors (such as AVLIMA). The MoU will also benefit Ethiopia by decreasing imports of processed food items.”

A multilayered challenge to durum wheat production

Supported by the Bill and Melinda Gates Foundation, CIMMYT and Digital Green (an organization creating digital tools to assist farmers) have been conducting durum wheat improved varieties were insufficiently promoted; the seed was not made adequately accessible to farmers; productivity was perceived by farmers as being low; and market linkage was poor. These multilayered challenges led farmers to prioritize bread wheat varieties, according to Kindie Tesfaye.

In response, CIMMYT structured its support around three main pillars: the organization helps farmers access seeds together with Oromia’s Seed Enterprise, provides farmers with digital advisory services to improve their productivity, and works with the private and public sectors to upgrade market linkages, as with the memorandum of understanding signed with Alvima Foods Complex Plc.

 

Celebrating collaboration in science

On the evening of 31 October 2023, CIMMYT held a partnership and alumni event with partners in China. Over 100 people from all over China joined the event in Beijing, which was chaired by He Zhonghu, distinguished scientist and CIMMYT country representative for China.

 

The event centered around the promotion and celebration of mutual collaboration in scientific research. In his opening speech, CIMMYT Director General Bram Govaerts celebrated the progress of the China-CIMMYT partnership, and highlighted what can further be achieved for global food security through continued partnership. His sentiments were echoed by the Vice President of the Chinese Academy of Agricultural Sciences (CAAS), Sun Tan, who expressed his high expectations and strong support for future collaboration between Chinese institutions and CIMMYT.

The event saw four Chinese institutions sign agreements with CIMMYT to promote mutual partnership: the Institute of Crop Sciences at CAAS, Huazhong Agricultural University, Henan Agricultural University, and Xinjiang Academy of Agricultural Sciences. Additionally, a ceremony was held in which 28 alumni and four partner institutions received awards for their contributions to scientific collaboration.

A fruitful partnership

China and CIMMYT have had a fruitful partnership over the past 45 years in areas including shuttle breeding, genomic research, sustainable crop systems and trainings that have greatly contributed to strengthening China’s food security with positive spillover effects to neighboring countries in the region.

The successful CIMMYT-China collaboration in shuttle breeding from the 1980s laid the foundations for the establishment of CIMMYT’s office in China in 1997. Bilateral cooperation then expanded to set up a Joint Lab between CIMMYT and the Ministry of Agriculture and Rural Affairs (MOARA), in which more than 20 Chinese agricultural research institutes also participated. More recently in 2019, CIMMYT and the Jiangsu Academy of Agricultural Sciences jointly opened a new screening facility for the deadly and fast-spreading fungal wheat disease, fusarium head blight.

CIMMYT has transferred approximately 26,000 wheat seed samples to more than 25 institutions in China, which are now using these materials in their breeding or crop improvement programs. As a result of these efforts, 300 wheat cultivars derived from CIMMYT germplasm have been released and are currently grown on 10% of China’s wheat production area. This collaboration between CIMMYT and China has yielded 10.7 million tons of wheat grain with an estimated value of $3.4 billion.

Additionally, CIMMYT-derived maize varieties have been planted on more than one million hectares across China, and 3,000 new inbred maize lines have been introduced through CIMMYT to broaden the genetic base of Chinese breeding efforts in southwestern provinces.

Nepal maize farmers share vision of a more profitable future with visiting agriculture officials

In a visit to 5 model sites for maize marketing in midwestern Nepal, 30 federal, provincial and local agricultural authorities were impressed with the coordination and capacity development among market actors, improved supply chain management and leveraging of government support, all of which are benefiting farmers and grain buyers.

Following visits to commercial maize fields and hearing stakeholders’ perceptions of progress and key lessons, the authorities proposed additional funding for irrigation, machinery, grain grading and crop insurance, among other support, and promised to help expand activities of the model sites, which were established as part of the Nepal Seed and Fertilizer (NSAF) project.

Led by CIMMYT with funding from the United States Agency for International Development (USAID) and in its second-last year of operation, the project is working to raise crop productivity, incomes and household food and nutrition security across 20 districts of Nepal, including 5 that were severely affected by the catastrophic 2015 earthquake and aftershocks which killed nearly 9,000 and left hundreds of thousands homeless.

The visitors included officials and experts from the Ministry of Agriculture and Livestock Development (MoALD); the Department of Agriculture (DoA); the Ministry of Land Management, Agriculture and Cooperatives (MoLMAC); the Agriculture Development Directorates (ADD) for Lumbini and Sudurpaschim provinces; the Agriculture Knowledge Centres (AKC) of Banke, Kailali, Kanchanpur, Dang, and Kapilvastu districts; the Prime Minister Agriculture Modernization Project (PMAMP) offices of Dang and Bardiya; and the National Maize Research Program; the Department of Livestock Services; along with NSAF project team members.

The participants interacted with farmers, cooperative leaders, traders, rural municipality officials and elected representatives, and feed mill representatives. Sharing their experiences of behavioral change in maize production, farmers emphasized the benefits of their strengthened relationships with grain buyers and their dreams to expand spring maize cultivation.

Shanta Karki, deputy director the General of Department of the DoA lauded CIMMYT efforts for agriculture growth, improved soil fertility and sustainable agriculture development through NSAF.

Madan Singh Dhami, secretary, MoLMAC in Sudurpaschim Province, emphasized the importance of irrigation, building farmers’ capacities and interactions with buyers, and applying digital innovations to catalyze extension.

CIMMYT scientists have been based in CIMMYT’s office in Nepal and worked with Nepali colleagues for more than three decades to boost the productivity, profitability and ecological efficiency of maize- and wheat-based cropping systems and thus improve rural communities’ food security and livelihoods.

Scientists convene in Kenya for intensive wheat disease training

An international cohort of scientists representing 12 countries gathered at the Kenya Agricultural and Livestock Research Organization (KALRO) station in Njoro for a comprehensive training course aimed at honing their expertise in wheat rust pathology.

The two-week program “Enhancing Wheat Disease Early Warning Systems, Germplasm Evaluation, Selection, and Tools for Improving Wheat Breeding Pipelines,” was a collaborative effort between CIMMYT and Cornell University and supported by the Wheat Disease Early Warning Advisory System (DEWAS) and Accelerating Genetic Gains in Maize and Wheat projects.

With a mission to bolster the capabilities of National Agricultural Research Systems (NARS), the training course attracted more than 30 participants from diverse corners of the globe.

Maricelis Acevedo, a research professor of global development at Cornell and the associate director of Wheat DEWAS, underscored the initiative’s significance. “This is all about training a new generation of scientists to be at the forefront of efforts to prevent wheat pathogens epidemics and increase food security all over the globe,” Acevedo said.

First initiated in 2008 through the Borlaug Global Rust Initiative, these training programs in Kenya have played a vital role in equipping scientists worldwide with the most up-to-date knowledge on rust pathogens. The initial twelve training sessions received support from the BGRI under the auspices of the Durable Rust Resistance in Wheat and Delivering Genetic Gain in Wheat projects.

This year’s training aims to prepare global scientists to protect against disease outbreaks that threaten wheat productivity in East Africa and South Asia. The course encompassed a wide array of practical exercises and theoretical sessions designed to enhance the participants’ knowledge in pathogen surveillance, diagnostics, modeling, data management, early warning assessments, and open science publishing. Presentations were made by DEWAS partners from the John Innes Centre, Aarhus University, the University of Cambridge and University of Minnesota.

The course provided practical, hands-on experience in selecting and evaluating wheat breeding germplasm, race analysis and greenhouse screening experiments to enhance knowledge of rust diseases, according to Sridhar Bhavani, training coordinator for the course.

“This comprehensive training program encompasses diverse aspects of wheat research, including disease monitoring, data management, epidemiological models, and rapid diagnostics to establish a scalable and sustainable early warning system for critical wheat diseases such as rusts, fusarium, and wheat blast,” said Bhavani, wheat improvement lead for East Africa at CIMMYT and head of wheat rust pathology and molecular genetic in CIMMYT’s Global Wheat program.

An integral part of the program, Acevedo said, was the hands-on training on wheat pathogen survey and sample collection at KALRO.  The scientists utilized the international wheat screening facility at KALRO as a training ground for hot-spot screening for rust diseases resistance.

Daisy Kwamboka, an associate researcher at PlantVillage in Kenya, said the program provided younger scientists with essential knowledge and mentoring.

“I found the practical sessions particularly fascinating, and I can now confidently perform inoculations and rust scoring on my own,” said Kwamboka said, who added that she also learned how to organize experimental designs and the basics of R language for data analysis.

DEWAS research leaders Dave Hodson, Bhavani and Acevedo conducted workshops and presentations along with leading wheat rust experts. Presenters included Robert Park and Davinder Singh from the University of Sydney; Diane Sauders from the John Innes Centre; Clay Sneller from Ohio State University; Pablo Olivera from the University of Minnesota; Cyrus Kimani, Zennah Kosgey and Godwin Macharia from KALRO; Leo Crespo, Susanne Dreisigacker, Keith Gardner, Velu Govindan, Itria Ibba, Arun Joshi, Naeela Qureshi, Pawan Kumar Singh and Paolo Vitale from CIMMYT; Chris Gilligan and Jake Smith from the University of Cambridge; and Jens GrÞnbech Hansen and Mogens S. HovmÞller from the Global Rust Reference Center at Aarhus University.

“I thoroughly enjoyed the knowledge imparted by the invited experts, along with the incredible care they have shown us throughout this wonderful training.”

Narain Dhar, Borlaug Institute for South Asia 

For participants, the course offered a crucial platform for international collaboration, a strong commitment to knowledge sharing, and its significant contribution to global food security.

“The dedication of the trainers truly brought the training to life, making it incredibly understandable,” said Narain Dhar, research fellow at the Borlaug Institute for South Asia.

The event not only facilitated learning but also fostered connections among scientists from different parts of the world. These newfound connections hold the promise of sparking innovative collaborations and research endeavors that could further advance the field of wheat pathology.

India transforms wheat for the world

In 2023, India reached a record wheat harvest of over 110 million tons. A partnership between CIMMYT and the Indian Institute of Wheat and Barley Research (IIWBR) now allows farmers to pre-order advanced wheat varieties, transforming the nation’s agriculture.

CIMMYT researcher receives Heroes Award

Maria Itria Ibba, a scientist at CIMMYT, received the inaugural Heroes Award from the Foundation for Innovation in Healthy Food. She received the award on October 29 at the ASA-CSSA-SSSA International Annual Meeting in St. Louis, Missouri, U.S.

Ibba, head of CIMMYT’s Wheat Chemistry and Quality Laboratory, received the honor in recognition of her outstanding leadership in launching the foundation’s Coalition for Grain Fiber initiative.

Together with her team at CIMMYT, Ibba works on improving the processing and nutritional quality of the bread and durum wheat lines derived from the CIMMYT spring wheat breeding programs. The research they conduct combines genetics and cereal chemistry, and one of the main focuses is to improve wheat grain dietary fiber. This effort begins with the development of efficient screening methods and the identification of germplasm with unique dietary fiber profiles.

The coalition seeks to improve the nutrition in staple foods without impacting their taste, mouthfeel or consumer price. It is simultaneously dedicated to establishing profit incentives for farmers and other food suppliers that enhance public health by delivering increased nutrient foods.

According to the coalition, improvements in the nutritional content of white and whole wheat flour may ultimately save thousands of lives and billions of healthcare U.S. dollars globally.

“Most people across the world do not consume enough dietary fiber, which is essential in the fight against various diseases,” says Ibba. “Increasing the dietary fiber content of a staple crop like wheat could have a significant positive impact on the health of wheat consumers. Our goal is to increase dietary fiber intake through the consumption of wheat products with greater fiber content.”

Plant breeders, food scientists, nutrition/health scientists and economists are partnering with the coalition to transform the food industry. They support non-GMO (not genetically modified organisms) approaches to increasing naturally occurring dietary fiber in grains.

Over 50 public and private-sector laboratory leaders in three countries and 23 U.S. states have engaged with the coalition, including from CIMMYT, Rothamsted Research, University of Nebraska, Lincoln, University of California, Davis, Cornell University and Bayer Crop Science.

The Nebraska Wheat Board provided support for the efforts of the foundation and the coalition.

“I feel humbled to have received the Heroes Award,” says Ibba. “I know that this award not only represents the work I have been doing, but also all the hard work that my team and my organization have been doing for several years.”

Staff of the Nepal Seed and Fertilizer (NSAF) project conducted a three-day “training of trainers” workshop on integrated soil fertility management and related practices for commercial rice farming, for 50 agricultural technicians from 50 farm cooperatives in districts of mountainous midwestern Nepal and its lowland Terai Region.

Held in Nepalgunj, midwestern Nepal, the workshop focused on the “4Rs” for soil fertilization—right source, right rate, right time, and right place—along with other best farming and soil nutrient stewardship practices for rice-based farming systems.

“Subject matter was comprehensive, covering variety selection, transplanting, weeding, management of nursery beds, fertilizer, irrigation, controlling pests and diseases and proper handling of rice grain after harvest,” said Dyutiman Choudhary, NSAF project coordinator and scientist at CIMMYT. “Topics relating to the integrated management of soil fertility included judicious application of organic and inorganic fertilizer, composting and the cultivation of green manure crops such as mungbean and dhaincha, a leguminous shrub, were also included.”

Support to sustainably boost Nepal’s crop yields

With funding from the United States Agency for International Development (USAID), the NSAF project promotes the use of improved seeds and integrated soil fertility management technologies, along with effective extension, including the use of digital and information and communication technologies.

Agriculture provides livelihoods for two-thirds of Nepal’s predominantly rural population, largely at a subsistence-level. Rice is the nation’s staple food, but yields are relatively low, requiring annual imports worth some $300 million, to satisfy domestic demand.

Workshop participants attended sessions on digital agri-advisories using the Geokrishi and PlantSat platforms and received orientation regarding gender and social inclusion concerns and approaches—crucial in a nation where 70% of smallholder farmers are women and exclusion of specific social groups remains prevalent.

“Topics in that area included beneficiary selection, identifying training and farmer field day participants, and support for access to and selection of improved seed and small-scale farm equipment,” explained Choudhary. “The participants will now go back to their cooperatives and train farmers, local governments and agrovets on improved rice production.”

Nepal scientists and national research programs have partnered with CIMMYT for more than three decades to breed and spread improved varieties of maize and wheat and test and promote more productive, resource-conserving cropping systems, including rotations involving rice.

Cream of the crop: Developing the next generation of wheat scientists is key to sustaining wheat production in Pakistan

On July 17-18, 2023, 87 wheat scientists gathered to learn about new approaches and methods for wheat improvement in Faisalabad, Pakistan. CIMMYT and the Wheat Research Institute, Faisalabad (WRI-FSD) jointly organized a two-day training. The course covered two topics: high throughput genotyping technologies and high throughput phenotyping platforms. The trainees, who were able to attend in person or remotely and 27% of whom were women, hailed from 17 NARES partners across Pakistan.

After being welcomed by the Director General of Ayub Agricultural Research Institute (AARI), Akhtar Ali, and CIMMYT’s Country Representative, TP Tiwari, participants received an update on the status of wheat in Pakistan from Muhammad Sohail, national wheat coordinator for the Pakistan Agricultural Research Council (PARC). Subsequently, WRI-FSD Director, Javed Ahmed, discussed wheat research in Punjab, where over 70% wheat is grown in Pakistan. Kevin Pixley, interim director of CIMMYT’s Global Wheat Program, joined the proceedings remotely for a conversation about CIMMYT’s and CGIAR’s collaboration with NARES. Participants discussed the model’s successes, bottlenecks, the role of NARES, and the potential for capacity development. The conversation generated broad interest and suggestions for enhancing the partnership’s effectiveness. Akhtar Ali, Muhammad Sohail, and Javed Ahmed all spoke very highly about CIMMYT’s support in Pakistan.

This event was organized as part of a collaborative project entitled “Rapid development of climate resilient wheat varieties for South Asia using genomic selection” that is jointly managed by Kansas State University and CIMMYT with funding from the USAID Feed the Future program.

“Training emphasized the need for an output-oriented researcher that covered the development of climate-resilient wheat varieties, given the environmental challenges we are experiencing like, drought and heat, and highlighted the importance of innovative methodologies and advanced tools for high throughput phenotyping and genotyping for sustainable and resilient wheat production in Pakistan” said Muhammad Ishaq, a senior research officer and one of the training participants from Kohat Research Station, Khyber Pakhtunkhwa.

At the conclusion of the training, Javed, direct of WRI Faisalabad, commended CIMMYT’s support and suggested continuing the pace of training. Dr. Tiwari stressed the importance of such efforts will help Pakistan’s scientists develop and deploy climate resilient, impactful wheat varieties to boost wheat production and reduce wheat imports in the country.

Wheat pathogen surveillance system set to expand through new investment

One of the world’s largest crop pathogen surveillance systems is set to expand its analytic and knowledge systems capacity to protect wheat productivity in food vulnerable areas of East Africa and South Asia.

Researchers announced the Wheat Disease Early Warning Advisory System (Wheat DEWAS), funded through a $7.3 million grant from the Bill & Melinda Gates Foundation and the United Kingdom’s Foreign, Commonwealth & Development Office, to enhance crop resilience to wheat diseases.

The project is led by David Hodson, principal scientist at CIMMYT, and Maricelis Acevedo, research professor of global development and plant pathology at Cornell University’s College of Agriculture and Life Sciences. This initiative brings together research expertise from 23 research and academic organizations from sub-Saharan Africa, South Asia, Europe, the United States and Mexico.

Wheat DEWAS aims to be an open and scalable system capable of tracking important pathogen strains. The system builds on existing capabilities developed by the research team to provide near-real-time model-based risk forecasts and resulting in accurate, timely and actionable advice to farmers. As plant pathogens continue to evolve and threaten global food production, the system strengthens the capacity of countries to respond in a proactive manner to transboundary wheat diseases.

The system focuses on the two major fungal pathogens of wheat known as rust and blast diseases. Rust diseases, named for a rust-like appearance on infected plants, are hyper-variable and can significantly reduce crop yields when they attack. The fungus releases trillions of spores that can ride wind currents across national borders and continents and spread devastating epidemics quickly over vast areas.

Wheat blast, caused by the fungus Magnaporte oryzae Tritici, is an increasing threat to wheat production, following detection in both Bangladesh and Zambia. The fungus spreads over short distances and through the planting of infected seeds. Grains of infected plants shrivel within a week of first symptoms, providing little time for farmers to take preventative actions. Most wheat grown in the world has limited resistance to wheat blast.

“New wheat pathogen variants are constantly evolving and are spreading rapidly on a global scale,” said Hodson, principal investigator for Wheat DEWAS. “Complete crop losses in some of the most food vulnerable areas of the world are possible under favorable epidemiological conditions. Vigilance coupled with pathogen-informed breeding strategies are essential to prevent wheat disease epidemics. Improved monitoring, early warning and advisory approaches are an important component for safeguarding food supplies.”

Previous long-term investments in rust pathogen surveillance, modelling, and diagnostics built one of the largest operational global surveillance and monitoring system for any crop disease. The research permitted the development of functioning prototypes of advanced early warning advisory systems (EWAS) in East Africa and South Asia. Wheat DEWAS seeks to improve on that foundation to build a scalable, integrated, and sustainable solution that can provide improved advanced timely warning of vulnerability to emerging and migrating wheat diseases.

“The impact of these diseases is greatest on small-scale producers, negatively affecting livelihoods, income, and food security,” Acevedo said. “Ultimately, with this project we aim to maximize opportunities for smallholder farmers to benefit from hyper-local analytic and knowledge systems to protect wheat productivity.”

The system has already proven successful, contributing to prevention of a potential rust outbreak in Ethiopia in 2021. At that time, the early warning and global monitoring detected a new yellow rust strain with high epidemic potential. Risk mapping and real-time early forecasting identified the risk and allowed a timely and effective response by farmers and officials. That growing season ended up being a production record-breaker for Ethiopian wheat farmers.

While wheat is the major focus of the system, pathogens with similar biology and dispersal modes exist for all major crops. Discoveries made in the wheat system could provide essential infrastructure, methods for data collection and analysis to aid interventions that will be relevant to other crops.

CIMMYT makes progress on some of the world’s top problems: 2022 Annual Report, “Harvesting Success”

CIMMYT targets some of the world’s most pressing problems: ending poverty, ensuring food for the future, mitigating climate change and improving the lives of farmers and consumers (especially women). CIMMYT is a CGIAR Research Center and has long been the world’s leading center for research on maize and wheat. This research capacity is being harnessed to achieve the crucial goals of climate resilience, and food and nutrition security.

Most of the world’s people depend on annual grain crops for their survival. Yet some of the world’s poorest men and women produce cereals. Annual grain farming has exacerbated climate change. The world’s great challenges of achieving climate resilience and nutrition security are being addressed by focusing CIMMYT’s research and development (R&D) on maize, and wheat, as well as on underutilized grain and legume crops.

Highlights from the 2022 Annual Report:

Annual cereal farming tends to release carbon into the atmosphere, while degrading the soil. Improving the soil takes years, and the high annual variation in weather demands long-term experiments. Field trials by CIMMYT over many years show that farmers can return carbon to the soil by using minimum tillage, rotating cereals with legumes, and by applying animal manure and strategic amounts of nitrogen fertilizer. As soil fertility improves, so do farmers’ yields.

Eleven million farmers in India alone produce maize, usually without irrigation, exposing families to climate-related disaster. Twenty new hybrids bred by CIMMYT out-perform commercial maize, even in drought years. One thousand tons of this heat-tolerant maize seed have now been distributed to farmers across South Asia.

Some wheat is rich in zinc and iron, which prevent anemia, especially in children. Yet naturally-occurring phytic acid in wheat blocks the body’s absorption of these minerals. A technique developed by CIMMYT lowers the cost of assaying phytic acid, so plant breeders in developing countries can identify promising lines of wheat faster. CIMMYT is also helping to reduce food imports by learning how other crops, like cassava and sorghum, can be blended with wheat to make flours that consumers will accept.

Some wheat hotspots are warm, dry, and subject to plant diseases. CIMMYT collaborates with plant breeders worldwide through the International Wheat Improvement Network (IWIN) to test promising new wheat lines in these tough environments. As more places become warmer and drier with climate change, CIMMYT and allies are developing wheat varieties that will thrive there.

Harvesting more maize in the future will depend on higher yields, not on planting more land. In plant breeding programs in Africa, South Asia and Latin America, CIMMYT and partners are already developing maize varieties and hybrids that will be released in just a few years. A review of these efforts reveals that annual yield increases will be about twice the rate achieved from 1973 to 2012.

Sorghum, millets, pigeon pea, chickpea and groundnuts have been favorite food crops in Africa for centuries. They are already adapted to warm, dry climates. CIMMYT is now working with national research programs to ensure that new crop varieties have the traits that male and female farmers need. Seed systems are being organized to produce more of Africa’s preferred crops.

Researchers can only breed new crop varieties if someone saves the old ones from extinction. CIMMYT does that with its world-class collection of wheat and maize seed. In 2022, CIMMYT’s two separate wheat and maize germplasm banks were combined into one. Modern techniques, such as vacuum-sealed seed packets and QR codes, allow rapid response to requests for seed from plant breeders around the world.

CIMMYT is helping Nepali farmers to plant maize in the lowlands, in the spring, when most land lies fallow. In 2022, CIMMYT provided training and investment to 2,260 farmers (35% women), who earned, on average, an additional $367 in one year. The added income allowed these farmers to invest in health care and schooling for their children.

Mexican farmers are saving money, harvesting more and selling their grain more easily. Some 4,000 farmers are now selling on contract to food manufacturing companies. The farmers lower production costs by using CIMMYT innovations in irrigation, fertilizer application and ecological pest control. Yields increase, the soil improves, and farmers find a ready market for their harvest.

The stories we have highlighted in this article are just some of the ones included in the Annual Report. See the full text of all the stories in “Harvesting Success” to learn how CIMMYT scientists are doing some of the most important research, for some of the world’s best causes.

India transforms wheat for the world

India can applaud a hallmark in national food production: in 2023, the harvest of wheat—India’s second most important food crop—will surpass 110 million tons for the first time.

This maintains India as the world’s number-two wheat producer after China, as has been the case since the early 2000s. It also extends the wheat productivity jumpstart that begun in the Green Revolution—the modernization of India’s agriculture during the 1960s-70s that allowed the country to put behind it the recurrent grain shortages and extreme hunger of preceding decades.

“Newer and superior wheat varieties in India continually provide higher yields and genetic resistance to the rusts and other deadly diseases,” said Distinguished Scientist Emeritus at CIMMYT, Ravi Singh. “More than 90 percent of spring bread wheat varieties released in South Asia in the last three decades carry CIMMYT breeding contributions for those or other valued traits, selected directly from the Center’s international yield trials and nurseries or developed locally using CIMMYT parents.”

Wheat grain yield in Indian farmers’ fields rose yearly by more than 1.8 percent—some 54 kilograms per hectare—in the last decade, a remarkable achievement and significantly above the global average of 1.3 percent. New and better wheat varieties also reach farmers much sooner, due to better policies and strategies that speed seed multiplication, along with greater involvement of private seed producers.

“The emergence of Ug99 stem rust disease from eastern Africa in the early 2000s and its ability to overcome the genetic resistance of older varieties drove major global and national initiatives to quickly spread the seed of newer, resistant wheat and to encourage farmers to grow it,” Singh explained. “This both protected their crops and delivered breeding gains for yield and climate resilience.”

CIMMYT has recently adopted an accelerated breeding approach that has reduced the breeding cycle to three years and is expected to fast-track genetic gains in breeding populations and hasten delivery of improvements to farmers. The scheme builds on strong field selection and testing in Mexico, integrates genomic selection, and features expanded yield assays with partner institutions. To stimulate adoption of newer varieties, the Indian Institute of Wheat and Barley Research (IIWBR, of the Indian Council of Agricultural Research, ICAR) operates a seed portal that offers farmers advanced booking for seed of recently released and other wheat varieties.

Private providers constitute another key seed source. In particular, small-scale seed producers linked to the IIWBR/ICAR network have found a profitable business in multiplying and marketing new wheat seed, thus supporting the replacement of older, less productive or disease susceptible varieties.

Farm innovations for changing climates and resource scarcities

Following findings from longstanding CIMMYT and national studies, more Indian wheat farmers are sowing their crops weeks earlier so that the plants mature before the extreme high temperatures that precede the monsoon season, thus ensuring better yields.

New varieties DBW187, DBW303, DBW327, DBW332 and WH1270 can be planted as early as the last half of October, in the northwestern plain zone. Recent research by Indian and CIMMYT scientists has identified well-adapted wheat lines for use in breeding additional varieties for early sowing.

Resource-conserving practices promoted by CIMMYT and partners, such as planting wheat seed directly into the unplowed fields and residues from a preceding rice crop, shave off as much as two weeks of laborious plowing and planking.

“This ‘zero tillage’ and other forms of reduced tillage, as well as straw management systems, save the time, labor, irrigation water and fuel needed to plant wheat, which in traditional plowing and sowing requires many tractor passes,” said Arun Joshi, CIMMYT wheat breeder and regional representative for Asia and managing director of the Borlaug Institute for South Asia (BISA). “Also, letting rice residues decompose on the surface, rather than burning them, enriches the soil and reduces seasonal air pollution that harms human health in farm communities and cities such as New Delhi.”

Sustainable practices include precision levelling of farmland for more efficient irrigation and the precise use of nitrogen fertilizer to save money and the environment.

Science and policies ensure future wheat harvests and better nutrition

Joshi mentioned that increased use of combines has sped up wheat harvesting and cut post-harvest grain losses from untimely rains caused by climate change. “Added to this, policies such as guaranteed purchase prices for grain and subsidies for fertilizers have boosted productivity, and recent high market prices for wheat are convincing farmers to invest in their operations and adopt improved practices.”

To safeguard India’s wheat crops from the fearsome disease wheat blast, native to the Americas but which struck Bangladesh’s wheat fields in 2016, CIMMYT and partners from Bangladesh and Bolivia have quickly identified and cross-bred resistance genes into wheat and launched wheat disease monitoring and early warning systems in South Asia.

“More than a dozen wheat blast resistant varieties have been deployed in eastern India to block the disease’s entry and farmers in areas adjoining Bangladesh have temporarily stopped growing wheat,” said Pawan Singh, head of wheat pathology at CIMMYT.

Building on wheat’s use in many Indian foods, under the HarvestPlus program CIMMYT and Indian researchers applied cross-breeding and specialized selection to develop improved wheats featuring grain with enhanced levels of zinc, a micronutrient whose lack in Indian diets can stunt the growth of young children and make them more vulnerable to diarrhea and pneumonia.

“At least 10 such ‘biofortified’ wheat varieties have been released and are grown on over 2 million hectares in India,” said Velu Govindan, CIMMYT breeder who leads the Center’s wheat biofortification research. “It is now standard practice to label all new varieties for biofortified traits to raise awareness and adoption, and CIMMYT has included high grain zinc content among its primary breeding objectives, so we expect that nearly all wheat lines distributed by CIMMYT in the next 5-8 years will have this trait.”

A rigorous study published in 2018 showed that, when vulnerable young children in India ate foods prepared with such zinc-biofortified wheat, they experienced significantly fewer days of pneumonia and vomiting than would normally be the case.

Celebrating joint achievements and committing for continued success

The April-June 2018 edition of the “ICAR Reporter” newsletter called the five-decade ICAR-CIMMYT partnership in agricultural research “
one of the longest and most productive in the world
” and mentioned mutually beneficial research in the development and delivery of stress resilient and nutritionally enriched wheat, impact-oriented sustainable and climate-smart farming practices, socioeconomic analyses, and policy recommendations.

Speaking during an August 2022 visit to India by CIMMYT Director General Bram Govaerts,  Himanshu Pathak, secretary of the Department of Agricultural Research and Education (DARE) of India’s Ministry of Agriculture and Farmers Welfare and Director General of ICAR, “reaffirmed the commitment to closely work with CIMMYT and BISA to address the current challenges in the field of agricultural research, education and extension in the country.”

“The ICAR-CIMMYT collaboration is revolutionizing wheat research and technology deployment for global food security,” said Gyanendra Singh, director, ICAR-IIWBR. “This in turn advances global peace and prosperity.”

According to Govaerts, CIMMYT has concentrated on strategies that foster collaboration to deliver greater value for the communities both ICAR and the Center serve. “The way forward to the next milestone — say, harvesting 125 million tons of wheat from the same or less land area — is through our jointly developing and making available new, cost effective, sustainable technologies for smallholder farmers,” he said.

Wheat research and development results to date, challenges, and future initiatives occupied the table at the 28th All India Wheat & Barley Research Workers’ Meeting, which took place in Udaipur, state of Rajasthan, August 28-30, 2023, and which ICAR and CIMMYT wheat scientists attended.

Generous funding from various agencies, including the following, have supported the work described: The Australian Centre for International Agricultural Research (ACIAR), the Bill & Melinda Gates Foundation, the Federal Ministry for Economic Cooperation and Development of Germany (BMZ), the Foreign, Commonwealth & Development Office of UK’s Government (FCDO), the Foundation for Food & Agricultural Research (FFAR), HarvestPlus, ICAR, the United States Agency for International Development (USAID), funders of the One CGIAR Accelerated Breeding Initiative (ABI), and the Plant Health Initiative (PHI).

Former CIMMYT wheat scientist, Mohan Kohli, receives Paraguay’s National Order of Merit award

Paraguay’s Minister of Foreign Affairs, Ambassador Julio CĂ©sar Arriola, recently bestowed on Man Mohan Kohli, retired wheat geneticist of CIMMYT the “Comendador” award of the country’s National Order of Merit, highlighting the scientist’s “
exceptional contribution to Paraguayan agriculture and economy.”

A native of India, where he completed schooling including a Ph.D. in wheat genetics, Kohli worked at CIMMYT during 1971-2004 on topics including spring x winter wheat crosses, resistance in wheat to the rust and other diseases, and the improvement and promotion of triticale, a wheat x rye hybrid.

In 1978 he was assigned to a CIMMYT regional program involving wheat breeding, development and training in collaboration with countries of the Southern Cone of South America, which included facilitating the regional testing and exchange of wheat breeding lines and selection data.

As of 2004, Kohli has been an active part-time consultant with Paraguay’s national wheat program and the Bioceres Group in Argentina.

“Funding ended for CIMMYT wheat research in Paraguay in 1993,” Kohli said. “In 2003 we started direct cooperation again through a joint venture including the Ministry of Agriculture and Livestock, the Paraguayan Chamber of Cereals and Oilseeds Exporters, and CIMMYT.”

“Back in 2003, Paraguay was producing about 320,000 tons of wheat each year and importing over 200,000 tons. Now, yearly output is around 1 million tons and the country exports almost a third of that.”

Kohli said the joint initiative had promoted higher-yielding wheat varieties and farming methods, lowered the costs of agrochemicals, and helped form associations involving farmers and millers—the complete cycle from sowing to marketing for wheat.

Paraguayans eat an average of over 85 kilograms of wheat each year as pasta, bread and other bakery products.

Kohli’s career has led him to work with science luminaries such as M.S. Swaminathan, Glenn Anderson, Joe Rupert, Cal Qualset, Warren Kronstad, Frank Zillinsky, and Sanjaya Rajaram, among others.

“I met CIMMYT scientist and eventual Nobel Peace laureate, Dr. Norman E. Borlaug, in 1967,” Kohli said. “We continued to meet every year on his visits to India and, when I was about to finish my Ph.D. in 1970, he invited me to join the team at CIMMYT.”

“It has been a privilege and honor to have worked alongside many dedicated colleagues at CIMMYT and national programs who have contributed significantly to building research capacities and global food security over the last 50 years. This award is dedicated to all of them and the farmers who have been the primary source of inspiration for our work”.
