As the world searches for effective solutions to mitigate and adapt to climate change while navigating the cost-of-living crisis, delivering food security goals alongside robust economic value is more imperative than ever in agricultural research.
CGIAR plays a vital role in this mission, aiming to transform food, land, and water systems in collaboration with its 15 Research Centers, such as CIMMYT. Now, a new study published in World Development comprehensively analyzes CGIARâs fiscal impact on global agricultural over nearly 60 years.
Additionally, investment in productivity gains for staple crops in developing countries has aided entire populations by securing lower food prices and generating large local growth multipliers, thus achieving a greater impact on poverty reduction when compared to productivity growth in other sectors.
CIMMYT contributes 40% of total CGIAR varietal impact
At least 221 million hectares in at least 92 countries were occupied by CGIAR crop technologies in 2020. Between 2016 and 2020, CIMMYT maize varieties accounted for 24.5 million hectares (11%) of this figure, while CIMMYT wheat varieties made up almost 74 million hectares (33%).
An example of how these CIMMYT varieties impact farmers can be seen in sub-Saharan Africa, where using improved maize seed led to an overall average increase of 38.9% in yields to 1,104 kilograms per hectare (kg/ha), equal to an increase of 429 kg/ha. With increased yields come increased profits and employment security for farmers and their families.
The frequency with which technologies are upgraded also signifies the impact of agricultural research and development (R&D) on crop productivity and the economy. On the 221 million ha planting area, many farmers utilize second or third generation technologies. For example, average varietal generation in maize is estimated to be 1.1, meaning that 10% of farmers use a second-generation variety, and most wheat farmers were also using second or third generation modern varieties. This highlights that ongoing crop research continued to impact productivity, even when the size of the adoption area remained constant.
Expanding the impact
As CGIARâs reach and capacity have grown, economic benefits are now apparent in an increased number of global regions compared to when its work began. Initially, most economic benefits came from wheat and rice farming in Asia; however, 30% of CGIAR crop technologies now occupy sub-Saharan Africa, generating a significant share of its impact. This region remains heavily reliant upon CGIAR-related varieties, so continued investment is encouraged to maintain and build on the positive outcomes achieved to date.
âConsidering the urgent need to attain nutrition security, CIMMYT always seeks ways to assure global food systems,â said Bram Govaerts, director general of CIMMYT. âThis thorough analysis is a strong validation of CIMMYTâs work and its significance not just for farmers and their immediate families, but for communities and generations into the future. Our collaborative partnerships with CGIAR Research Centers and National Agricultural Research Systems (NARS) are integral in delivering successful projects that enable smallholder farmers to maximize the potential of their land.â
While similar studies have been undertaken in the past, this work takes a unique approach by drawing on a wider range of evidence built on country- and crop-specific data, such as the adoption of crop improvement technologies and productivity impacts per hectare, thereby providing a more granular assessment of CGIARâs economic inputs.
Successful global wheat disease surveillance and monitoring has resulted in early detection of wheat stem rust Ug99 in Nepal. A combination of vigilant field surveys and sampling by Nepalâs National Plant Pathology Research Centre (NPPRC) and National Wheat Research Program (NWRP), supported by rigorous and accurate disease diagnostics at the Global Rust Reference Center (GRRC), Denmark, resulted in confirmed detection of the Ug99 strain named TTKTT. The long running and sustained surveillance efforts undertaken by NPPRC and NWRP, including off-season surveys, proved vital in the detection of Ug99 in Nepal. Confirmed results were obtained from two field samples collected in early November 2023 from off-season summer wheat crops in Dolakha district, Nepal. Repeated experiments and high quality pathotyping and genotyping at GRRC confirmed the results.
âThe combination of molecular genotyping of incoming samples, without prior recovery in our laboratory and independent diagnostic assays of recovered stem rust isolates, confirmed the presence of Ug99 and a highly virulent race variant termed TTKTT,â says professor Mogens HovmĂžller, leader of the GRRC at Aarhus University in Denmark.

Ug99 was first detected in East Africa in 1998/99, and its unique virulence sparked fears that a large proportion of wheat cultivars globally would be at risk from this potentially devastating disease. The international wheat community came together through the Borlaug Global Rust Initiative (BGRI) to address the threats posed by Ug99. The BGRI partners have successfully monitored the evolution and spread of Ug99 and bred hundreds of resistant wheat varieties that are now being grown at scale in priority wheat growing regions. Migration of Ug99 from Africa to other regions, including South Asia, was always seen as likely due to the transboundary nature of the disease and long-distance dispersal of rust spores by wind.
Detection of a Ug99 race in Nepal is not therefore a surprise, but it highlights the effectiveness of the wheat rust surveillance and monitoring systems that have been developed. The disease was present at extremely low levels in the fields in Nepal, and early detection is one of the main factors in preventing disease spread. Other factors also contribute to reduced risk. The wheat on which the Ug99 race TTKTT was detected were fodder crops and cut soon after the surveys were completed, which prevented further buildup of disease. In addition, no wheat is grown in the main season in these areas, with farmers shifting to cultivation of potato (a non-host crop for stem rust).
According to Suraj Baidya, senior scientist and chief of NPPRC, âExtensive follow up surveys in the Dolakha detection area by NPPRC in the 2023/24 main season resulted in no wheat being observed and no detection of stem rust.â Similarly, extensive surveys by NPPRC throughout other wheat growing areas of Nepal in the 2023/24 main season have resulted in no reports of stem rust in the country. To date, extensive surveys in other countries in South Asia (Pakistan, Bangladesh, Bhutan) have not detected stem rust in 2023/24.
Although the current risk of stem rust outbreaks is considered to be low, detection of the Ug99 race TTKTT in Nepal is a clear reminder of the threat posed to wheat production in South Asia by the incursion of virulent stem rust races or other plant diseases of concern. âThe spread and risk from transboundary diseases like stem rust is increasing,â says Dave Hodson, leader of the Wheat Disease Early Warning Advisory Systems (DEWAS) project at CIMMYT. âSustained and increased surveillance efforts are needed across the region and expanded to include other important emerging diseases.â Successful deployment of Ug99 resistant cultivars through the BGRI partners, including CIMMYT, ICARDA and NARS, has decreased vulnerability, but it is important to note that the race TTKTT is a recently evolved variant of Ug99 with additional virulence compared to the original strains. As a result, not all cultivars in South Asia may have effective resistance today. Screening of germplasm and major cultivars from South Asia against TTKTT at the Kenya Agriculture and Livestock Research Organization (KALRO)/CIMMYT international stem rust screening nursery in Kenya is extremely important to get an accurate picture of current vulnerability.
The details of the diagnostic confirmation of Ug99 in Nepal are available at the GRRC website (see GRRC lab report)
Work on wheat disease surveillance and monitoring, plus breeding of resistant varieties is being supported by the DEWAS and AGG projects funded by BMGF and FCDO, UK.

Thirty-three-year-old Promila Rani Mondol lives in Baliakandi Upazila in Bangladesh with her husband, four daughters, and mother-in-law. The familyâs main source of livelihood is agriculture. Promila has become a successful machinery solution provider (MSP), under the USAID-funded Feed the Future Cereal Systems Initiative for South AsiaâMechanization Extension Activity (CSISA-MEA). She and her husband are the main earning members of the family.
In Rajbari district, around 100 miles away from Dhaka, the capital of Bangladesh, agriculture is the primary livelihood for the community. Farmers engage in crop cultivation across three different seasons, focusing on crops such as rice, wheat, maize, jute, mustard, spices, and vegetables. In 2014, Promilaâs family had barely two acres of cultivable land, and her husband was the sole breadwinner. Their average monthly income was US $91, which made it challenging to cover everyday expenses. To increase their family income, she began assisting her husband in crop production activities by planting seeds of jute, maize, wheat, mustard, and spice crops.
In 2014, the family became involved with the CSISA-MI project. Initially, they owned a power tiller. The project assisted them to purchase a power tiller-operated seeder attachment for land cultivation and line sowing. In 2018, Promila received training in line sowing techniques, including seed calibration using the power tiller operated seeder (PTOS) machine which was equipped with a starter kit. She began line sowing Rabi crops such as wheat, mung beans, sesame, and mustard. During the Kharif season, she engaged in line sowing jute.
After the launch of the CSISA-MEA in 2019, Promila participated in several activities including hands-on training on rice transplanter operation, one-acre mechanized rice transplantation demonstration by CSISA-MEA for her service business expansion, seedling raising training, two-day training on agricultural machinery operation maintenance and troubleshooting, and two exposure visits on rice transplanter service business models. With the assistance of CSISA-MEA, she organized several meetings to connect mat seedling (seedlings grown on a special mat or seedling tray), entrepreneurs, farmers, and MSPs, which led to the expansion of her business prospects. Additionally, CSISA-MEA linked her with the Department of Agricultural Extension, where she procured 1,750 seedling raising trays and 750 kg of seed support for mat seedling raising, significantly boosting her business growth.
In 2023, Promila bought a rice transplanter before Aman season (mid-July to mid-November-December) with a 50% government subsidy. CSISA-MEA helped her get the government subsidy and connected her with the VPKA foundation, which provided her with loan at a low-interest rate of 4%, along with a flexible repayment plan.

During the Aman season, she provided rice transplantation services in 20 hectares of land benefiting approximately 150 farmers. During that season, her total earning was US $1,640. Additionally, in 2023, she earned approximately US $1,047 by line sowing aus rice and jute; and line sowing wheat, sesame, and mustard by PTOS during the Rabi season. Through her network of contacts with farmers across three blocks (shalmara, baliakandi, and nobabpur in Rajbari district), she offers machine rice transplantation services using the seedlings.
What sets her apart is not just her success as an MSP, but her commitment to breaking gender norms and inspiring other women in her community. Currently, with an annual income of US $2,276 and a profit margin of US$1,184, she has become a community leader, encouraging 15 other women to venture into farming and seedling raising services.
“With just one day of cultivation and seeding service, I can cover my daughter’s tutorial expenses for an entire month. The support from CSISA-MEA has made me more self-reliant as an MSP and increased my confidence in meeting family expenses,” says Promila.
Currently, 15 women in her community offer farming and seed planting services. Others, such as Sunita Rani, Niba Rai, Rakoli, Dipti, Mita, and Angoli, are inspired by her. While seven women can now operate the rice transplanter machine in the fields, others are showing an interest in the same. This is a significant and positive change in the community initiated by Promila.
Her impact extends beyond her own success; she has sparked a positive change in her community’s perception of women in agriculture. As the vice president of the MSP Networking Committee in Rajbari district, she continues to shoulder responsibilities, contributing not only to her family’s well-being but also to the larger narrative of women empowerment in Bangladesh.
In a landmark initiative to bolster sustainable agriculture and food security, the consultative workshop ‘Bottlenecks to Expansion of Pearl and Finger Millets in Africaâ marked a pivotal step towards revitalizing millet cultivation across the continent. Spearheaded by the Bill & Melinda Gates Foundation, in collaboration with CIMMYT and the Senegalese Institute of Agricultural Research (ISRA), a meeting held in Senegal united global experts to unlock the untapped potential of millets as a cornerstone of sustainable agriculture and food security in Africa.
The discussions included identifying the symptoms of the problem, underlying issues causing these symptoms, and the interventions needed to be implemented to address these issues. This collaborative efforts among national and international organizations including government bodies, research institutes, and NGOs, demonstrated the goal of revitalizing millet cultivation through partnerships.

The United Nations General Assembly declared 2023 the International Year of Millets to raise awareness of and direct policy attention to millets’ nutritional and health benefits and their suitability for cultivation under adverse and changing climatic conditions.
Long overlooked but brimming with potential, millets offer a sustainable solution for both farmers and consumers in terms of profitability, adaptability, and sustainability in farming, as well as healthier dietary options for consumers.
Lessons learned from India
India, a key player in millet production, provided valuable insights into millet cultivation and consumption, providing a potential model for Africa to emulate in its millet-related strategies.
To understand the growth of millets in India, the Indian Ambassador to Senegal, Naba Kumar Pal, highlighted the strategies used by the Indian government to raise awareness about millets as a nutritious cereal that contributes to food security and provides a nutritious dietary option aimed at eliminating hunger and improving nutrition in his opening remarks.
âThe first step the government did was to rebrand millets from âcoarse grainsâ to ânutri-cerealsâ, a move that has significantly increased domestic consumption and market interest of millets in India,â said the ambassador.

In Africa, millets are under appreciated and not utilized as crops. They are often labeled as a ‘poor manâs crop,’ ‘neglected crop,’ or ‘orphan cropâ. Â The negative connotations have, among other areas, influenced consumers’ perceptions. By changing the vocabulary from demeaning to empowering, milletsâ image can be transformed from an overlooked option to a crop of choice in Africa.
The workshop also delved into policy advocacy and commercialization efforts in India, and how these strategies could be replicated in African contexts. Tara Satyavati and Dayakar Rao, representing Indian institutions, shared insights on millet production, nutritional evaluation, and the development of value-added products. The importance of policy intervention, such as increasing the Minimum Support Price (MSP) for millets and including them in public meal programs in India, was discussed. These measures not only provided financial incentives to farmers but also increased accessibility and consumption among the general population.
The two asserted that âmillets offer a sustainable solution for both farmers and consumers in terms of profitability, adaptability, and sustainability in farming, as well as healthier dietary options for consumers.â
Millets are adaptable to diverse climates, have low water requirements, and provide nutritional benefits. African countries, which face similar issues in terms of climate change and food security, can use millets as a crop to promote environmental sustainability and economic viability.
National and international collaborations
A panel discussion shed light on national and international initiatives that highlighted collaborative efforts in crop improvement and millet innovations. On the national level, Hamidou Diallo from the Ministry of Agriculture, Rural Equipment, and Food Sovereignty of Senegal (MAERSA) outlined a multi-pronged approach for Senegal. These approaches included increasing millet production, providing high-quality seeds, equipping local producers with essential tools and equipment, providing fertilizers to farmers, and expanding the overall cultivated areas of millet. These efforts represent a focused approach to leveraging agricultural innovation in millets to improve livelihoods and income for small-scale farmers.
âAligning with the needs of the local community ensures the initiatives are impactful and resonate with the agricultural landscape and community needs,â he emphasized.
Insights into the international initiatives included discussions on innovative initiatives in the Dryland Crop Program (DCP), presented by Dryland Crops Program Director and Wheat Program Director Kevin Pixley, included the establishment of the African Dryland Crops Improvement Network, gene editing, a legumes mining project and the Vision for Adapted Crops and Soils (VACS) project, that will include millets as a prioritized crop.
âWe need to find innovative ways to reach more farmers with options to improve their livelihood and popularize millets across different market segments,â said Pixley.

Other topics covered included insights from the United States Agency for International Development (USAID) innovation lab on sorghum and millets, emphasizing the importance of African-led projects and addressing the knowledge gap between African and U.S. researchers.
Makiko Taguchi of the Food and Agriculture Organization of the United Nations (FAO) emphasized the importance of global engagement in promoting millets as a sustainable and nutritious food source for global food security and agricultural development and highlighted the various initiatives and projects born of the International Year of Millets. Douglas Gayeton, co-founder of The Lexicon emphasized the role of effective messaging in changing people’s perceptions of millets. He underscored the importance of shifting away from terms like âneglectedâ and âorphanedâ crops to more positive empowering language that resonates with consumers and policy makers.
CIMMYT’s role in dryland crop innovation
Recognizing the ever-evolving needs of society at large, CIMMYT began an initiative to advance research and broaden its impact by implementing the Dryland Crops Program. This approach is based on CIMMYT’s 2030 strategy, which will shape agriculture’s future as a driver of climate resilience, sustainable, and inclusive agricultural development, and food and nutrition security, all while meeting the United Nations Sustainable Development Goals and Africa 2063 by promoting food security, improving nutrition, and mitigating the effects of climate change.
The meeting underscored the immense potential of millets in Africa to contribute to a resilient and nutritious future, reinforcing the need for continued collaboration, innovation, and investment in this vital crop. With the right mix of policy support, technological innovation and market development, millets could be the key to Africaâs resilient and sustainable agricultural future. The workshop concluded with a call to action for stakeholders to collaborate and implement innovative practices to enhance the growth of the millet sector in Africa.
âA better understanding of the links between gender roles in household decision-making and the adoption of technologies can enhance the uptake of innovations in smallholder farming systems,â concludes a recently published paper by CIMMYT. The paper connects womenâs bargaining power in households with the adoption of rust resistant wheat varieties, based on the work of Accelerating Genetic Gains in Maize and Wheat (AGG) in Ethiopia.
âWhile an emerging body of literature finds positive correlations between womenâs influence in household decision-making and socioeconomic, health, and nutritional outcomes, few studies have analyzed the links between intra-household decision-making and the adoption of agricultural technologies,â said Michael Euler, agriculture research economist at CIMMYT.
A case study in Ethiopia
For this study, researchers used a dataset from Ethiopian wheat-producing households.
Ethiopia is the second-largest wheat producer in Africa, with an aggregate grain production of 5.5 million metric tons and 4-5 million farmers engaged in cultivation. The Ethiopian Highlands are a hot spot for wheat rust. With recurrent epidemics in the last decade, the emergence of new strains of wheat rust increased production risks. On the positive side, farmers seem to be responsive to the management of rust diseases. Rust-resistant bread wheat varieties, released since 2010, have been widely adopted by smallholder farmers across Ethiopia.
The CIMMYT study surveyed 1,088 wheat-producing households in Ethiopia to analyze the links between womenâs role in household decision-making concerning crop production and the adoption and turnover rates of rust-resistant wheat varieties. Female and male members from the same households responded separately, which facilitated capturing individual perceptions and the intra-household dynamics in decision-making.

Intra-household decision-making arrangements and wheat varietal choice
Overall, the study reveals a positive association between womenâs role in decision-making regarding the selection of wheat seed and the adoption of rust-resistant wheat varieties and wheat varietal turnover. Findings may be related to differences in risk aversion between women and men farmers. While women farmers may tend to advocate for the adoption of rust resistant varieties to avoid potential financial difficulties that arise from purchase of fungicide in the growing season, men farmers may be more inclined to adopt high yielding varieties and use fungicides to combat rust within the season.
Spouses may agree or have different opinions regarding their decision-making roles. Spousal agreement on the woman having a role in making crop variety decisions is associated with higher adoption rates compared to spousal agreement that the woman has no role. Joint decision-making with mutually uncontested spousal roles may yield better outcomes due to larger combined exposure to information, as well as spousal discussion and reflection on potential implications of the varietal choice decision.
Conclusion: It is about negotiation, contestation and consensus
Household decisions, including the decision to adopt agricultural technologies often result from negotiation, contestation, and consensus between wife and husband. This process is shaped by diverging interests, motivations and objectives, while its results are determined by different levels of individual bargaining power. âOur findings indicate that womenâs ownership of agricultural land and household assets is strongly associated with their active role in household decisions on wheat varietal choice, and with spousal agreement,â said Moti Jaleta, senior agricultural economist at CIMMYT. The dynamics in intra-household decision-making are likely to influence householdsâ adoption of agricultural technologies.
Disregarding the dynamics in decision-making implies that households are unilateral decision-makers, a scenario which probably does not hold true considering the level of spousal disagreement regarding their roles and influence in choosing crop varieties. A deeper understanding of the connections between gender dynamics in household decision-making and adoption choices can enhance the efficiency of public extension systems, increase the adoption rates of modern innovations, improve agricultural productivity, and enhance livelihoods in smallholder agriculture.
The third edition of Scaling Scan, a user-friendly tool that helps teams reimagine innovation scaling processes, was launched in February 2024.
Developed six years ago by CIMMYT and partners, the tool assesses the status of ten scaling âingredientsâ such as business models, finance, evidence, public sector governance, etc. that are considered critical to achieving a scaling ambition. The tool highlights what project teams need to pay attention to on the journey to reach scale. It emphasizes the need to think strategically about potential scaling bottlenecks right at the beginning of the project.
The new edition incorporates feedback across users from voluntary organizations, CGIAR, and private companies, and responds more effectively to climate change and gender inclusivity challenges.
Features of the new edition: inclusive, socially responsible, and accessible
The third edition was developed by subject matter experts from CIMMYT, SNV the Netherlands, the Deutsche Gesellschaft fuer Internationale Zusammenarbeit (GIZ), the Food and Agriculture Organization of the United Nations (FAO), and the Alliance of Bioversity International and Center for Tropical Agriculture (CIAT).
There is more focus on scaling innovation as a means to contribute to food systems transformation with an upgrade on systems check. Users can go through the x-curve to reflect on what dominant technology or practice can be scaled down to make space for CIMMYTâs âinnovation of interestâ.
The upgraded tool takes into consideration social responsibility, acknowledging intersectional trade-offs for the beneficiaries when they scale innovations. It helps reflect upon who will win or lose from the scaling of these innovations, and how the scaling ambition can also include capacity-building and equality.
The parameters of environmental responsibility, which previously focused on how to use resources, now also includes an analysis of potential trade-offs and risks of scaling innovations.
Researchers and program managers still use linear approaches to scaling which are not suitable for complex development problems such as hunger and poverty. The latest edition improves the equity of scaling. The new edition is also more accessible and user-friendly; the interface is upgraded and is available in English, Spanish, and French
The new version includes updated tools to help users further analyze and plan their scaling strategies by strengthening their lowest ingredient.

Partners from the Africa Dryland Crop Improvement Network (ADCIN) from 16 institutes in Africa came together for a four-day workshop in Nairobi, Kenya, during 19-22 September 2023, to critically review and optimize breeding pipelines for newly formed breeding programs. The meeting provided an opportunity for multidisciplinary scientists to better understand each other’s significant roles and contributions in achieving optimized breeding pipelines.
Nine female and 28 male scientists working across 14 countries made up the group of experts at the workshop, which included crop breeders, quantitative geneticists, crop protection scientists, genomics experts, and data analysts. Together, they collaboratively developed, assessed, and refined the various stages and processes of breeding pipelines. Most participants were crop breeding leads from the national agricultural research and extension systems (NARES) and CGIAR Research Centers, as well as members of the Breeding Informatics Working Group A, the first of its kind as a strategic leadership group of crop breeding experts.
The workshop sponsored by CIMMYT focused on improving genetic gains across six crops: chickpea, pigeon pea, finger millet, pearl millet, groundnut, and sorghum. The workshop was organized by CIMMYT experts, Abhishek Rathore, breeding data and informatics expert, Keith Gardner, quantitative geneticist, and Roma Rani Das, biometrician, and quantitative geneticist experts from the CGIAR Accelerated Breeding Initiative, Dorcus Gemenet and Christian Werner.
Multidisciplinary expertise in action
Under the guidance of the Associate Program Director and the Breeding Lead for Dryland Crops, Harish Gandhi, participants engaged in an array of advanced genetic approaches, statistical techniques, and quantitative concepts presented by the participating experts from CIMMYT and CGIAR Accelerated Breeding.
Each breeding program schema was reviewed from detailed quantitative genetic aspects and agreed project criteria, including choosing parents, the optimum number of parents, crossing designs, the number of generations, methodologies, testing strategies, and analytical frameworks. The group deliberated on the breeding strategies tailored for respective market segments and target product profiles to further improvise and optimize breeding pipelines to enhance the programsâ efficiency.
Agreements were reached on the number of founder parents, the number of crosses and progenies in various generations, line development method, evaluation and testing strategy, time until parental selection (cycle time), marker assisted selection (MAS), genomic selection (GS) strategy, making routine use of molecular markers for QA/QC. The team also finalized the breeding strategies tailored for respective market segments and target product profiles to further improvise and optimize breeding pipelines aimed at higher genetic gains.
In coordination with crop breeders from CIMMYT, the NARES dryland crop breeding leads presented the current schematics of breeding pipelines for both line and hybrid breeding, highlighting the market segment, Target Product Profile (TPP) and Target Product Environment (TPE).
The breeding informatics team also showcased the upcoming Dryland Crops Trial Information System dashboard, a one stop shops to capture, host, and provide information on the trials organized by the networkâs NARES breeders across Africa.
The value of partnership working was frequently highlighted by the speakers. Michael Quinn, lead of the CGIAR Accelerated Breeding Initiative, gave an overview of the initiativeâs objectives and high-level goals in 2023, emphasizing the need to foster dialogue and alignment across breeding teams. He also underlined the importance of such hand-in-hand meetings for fostering cross-regional and cross-institute learning.
âPlant breeding has always been at the center stage of crop improvement, but it has become more and more important lately, and there is a need to bring more collaborative efforts across disciplines to realize higher genetic gains in our breeding programs,â said Kevin Pixley, Dryland Crops program director and Wheat program director during his virtual presentation.
âInteraction with the breeding leads from CIMMYT and the NARES in East and Southern Africa (ESA) and West and Central Africa (WCA) and other experts helped in cross learning from the advanced breeding programs,â said Maryam Dawud, plant breeder at the Lake Chad Research Institute in Nigeria. Such workshops are needed for developing optimized breeding pipelines, and we will need more such in-person workshops on advanced data analysis.â
Next steps for dryland crops
During the workshop, network partners came up with an optimized breeding pipeline incorporating advanced quantitative genetic and statistical principles aligned with the latest scientific advancements and market demands. The group further developed a six-month actionable plan split by region to address common bottlenecks across the crops, such as capacity building in data analysis, modernizing digital infrastructure, training and enhancing human capacity in the use of equipment, and managing staff turnover.
All these deliberations provided the network partners with better insights and hands-on-experience to design their breeding pipeline, outlining specific steps, responsibilities, and timelines for implementing the identified optimizations. This preparatory work will ensure there is a targeted and coordinated effort toward pipeline enhancement and accelerated genetic gain for dryland crops in the region.
Happy Daudi, head, Groundnut Research Program at Tanzania Agricultural Research Institute (TARI), who participated in the workshop, stated, âBringing in multidisciplinary experts provided a great opportunity to integrate various concepts of population improvement, product development, and deploying advanced statistical approaches for optimizing our breeding pipeline for achieving higher genetic gains, and accelerated variety turn over.â

In Zimbabwe, the traditional, laborious, and time-consuming small grain processing may soon belong to the past, thanks to a game-changing technology: a multi-crop thresher. This scale-appropriate machine offers a smarter and less strenuous way to produce high-quality small-grain meals, including in drought-prone regions, without being contaminated with sand or stone particles.
âOne of the main impediments to large-scale adoption of sorghum and millet in drought-prone areas is the laborious task of threshing. This has been solved by introducing multi-crop threshers, which form a central part in the business of mechanization service providers in rural Zimbabweâ, says Christian Thierfelder, principal scientist and project lead for the Mechanization and Extension Activity.
The introduction of the multi-crop thresher not only alleviates the physical strain of manual threshing but also enhances the overall quality of small-grain products. This innovation is a crucial step forward in promoting the production and consumption of small grains in Zimbabwe, contributing to food security and improved livelihoods for farmers.
This innovation was introduced by the Feed the Future Mechanization and Extension Activity, implemented by CIMMYT and funded by the United States Agency for International Development (USAID), to address the challenges of traditional small grain processing and offer new market opportunities to farmers.

Small grain production and consumption has traditionally been a household favorite in Zimbabwe due to its rich nutritional content. However, the sand content and gritty texture, often associated with sorghum or millet meals, have led to a decline in consumersâ interest in it. The main culprit? The traditional method of manual threshing on the soil, a strenuous and time-consuming process that incorporates sand and gravel particles into the threshed grains (and then into flours), resulting in an unpleasant eating experience.
In Zimbabwe and across the region, small grain processing has been characterized by the arduous task of manual threshing using sticks. Women, often at the forefront of this task, repeatedly beat the heads of small grains on hard surfaces, such as granite or hard clay, to separate the grains. Despite efforts to minimize contamination by threshing them into sacks or on plastic sheets, the gritty taste persists. The subsequent winnowing, roasting, and milling do little to eliminate tiny soil and stone particles from the final product (flour) as physical separation is technically challenging.
The multi-crop thresher for smooth results
âPowered by an 8 HP diesel engine, the multi-crop thresher is a perfect machine to process sorghum, millets, maize (husked or un-husked), wheat, cowpea, sugar beans, and soybean,â says Abdul Matin, mechanization specialist and technical lead of the Mechanization and Extension Activity. âIt is locally made in Zimbabwe and designed to promote mechanization as a business as it can easily be transported. It has high threshing efficiency, is fuel-efficient, easy to operate, and women friendly.â
The operator simply feeds the crop into the inlet hopper, and as it passes through the threshing drum, the machine efficiently separates the grain from the chaff, releasing clean grain through the outlet chute. âThe thresher will help reduce decline of small grain production in the country and complement government efforts to expand its cultivation in Natural Regions IV and V in Zimbabwe,â Matin added. When operating the machine efficiently, one can thresh up to 0.5 tons per hour for small grains.

CIMMYT organized awareness meetings, including the 2023 Seed and Mechanization Fairs, for farmers to witness the speed and quality performance of the multi-crop thresher. They could also assess the quality of pearl millet processed using the thresher and others threshing wheat in an irrigation scheme showcasing the efficiency of the process and improved grain quality.
“In our region, harvesting small grains was always laborious,” explains Paidamoyo Kaseke from Ward 4 in Chimanimani district, Manicaland province. “But thanks to the multi-crop thresher, it’s now much easier. It operates quickly and efficiently, delivering clean grains that we can promptly take to the mill. This technology has revolutionized our harvesting process, significantly reducing the time and effort required.”
“Not only do we promote new and effective technologies such as the multi-crop thresher in the project, but we also seek solutions for farmers without high incomes to be able to afford the thresher. That is why we are partnering with two Zimbabwean banks to make small-scale loans accessible to farmers at affordable rates and tenure times. This way, we can effectively scale the access to scale-appropriate mechanization solutions.â says Leon Jamann, chief of party for the Mechanization and Extension Activity.
As the 2023-2024 farming season has been dry with erratic rainfall, rainfed dependent farmers already face drought in large areas of Zimbabwe. However, the promotion of more climate-resilient small grains in 2023âdeclared by the United Nations the International Year of Milletsâemphasizes their adaptability to climate change and their high nutritional value. The multi-crop thresher, a vital component of this initiative, ensures that farmers can efficiently process small grains despite the challenging climate conditions.

In the eastern region of Honduras, Mirian Lizeth Torres, an agroindustrial engineer who graduated from the National Autonomous University of Honduras, is making a difference. Her commitment to agricultural sustainability and the empowerment of local communities through sustainable agriculture is evident in her work with the Eastern Regional Farmers Association (ARSAGRO, for its acronym in Spanish) and with her participation in the InnovaHub Oriente, set within the framework of the AgriLAC Resiliente initiative.
âIn 2023, I volunteered at ARSAGRO, addressing crucial issues with producers, from events and extension to projects with CIAT that focused on the assessment of plots, water, soil, forest, pests and diseases, bean nutrition, grain quality, among others,â said Mirian, highlighting the breadth of her experience.
Her participation in the InnovaHub Oriente has been key to integrating theory and practice in the field. âI am a student of the conservation agriculture course, where I have explored agronomic practices that improve the sustainability of crops, creating more resilient systems,â she highlights. âThese practices are shared with producers through innovation modules, which are plots where conservation agriculture innovations are implemented and compared, side by side, with conventional methods.â
Mirian knows the importance of communicating this knowledge to communities. âAt events held on these plots, we shared practices and knowledge, reaching producers who were not familiar with these technologies,â she explains. âThanks to AgriLAC, in 2023 we contributed significantly to the empowerment of producers and organized groups in eastern Honduras.â
Additionally, Mirian is proud of her role as an inspiration for the inclusion of youth and women in agriculture. âAt every event we organize, we see increasing participation of young people and women,â she states. âThe empowerment of women in agricultural activities has been notable, with many resuming activities in the field through the transfer of knowledge.â
Looking to the future, Mirian hopes to further encourage youth participation. âMy invitation to young people is not to abandon the field; it is that they get involved in agricultural issues to contribute to the livelihood of their families and, at the same time, reduce migration,â she states with determination.
In a world where sustainable agriculture is essential, Mirian Lizeth Torres has assumed solid leadership from the field, helping her community move towards a more sustainable and equitable agricultural future.
Looking to the future, Mirian hopes to further encourage youth participation. âMy invitation to young people is not to abandon the field, but rather that they get involved in agricultural issues to contribute to the livelihood of their families and, at the same time, reduce migration,â she states with determination.
Juliana Moises tends her soybean plot. (Photo: CIMMYT)
From the rich plateau landscapes of Angonia district in the Tete province of Mozambique emerges a tale of determination and hard work. Juliana Nicolau Moises, a mother of four, has been a devoted soybean farmer for more than a decade, tending to a crop whose pods carry the potential for value-added products, including milk and porridge for her children. But one wonders, what motivates smallholder farmers like Juliana to invest their efforts in soybean production.
âI have never looked back on producing soybeans,â reflects Moises. âThis legume crop has allowed me to feed my family and meet my household needs, let alone the cash income from sales of the surplus crop. It has taken a lot of hard work and resilience to navigate through the complexities of soybean production.â
Entering her second season of implementing the Chinyanja Soy Use Case trials with CGIAR’s Initiative on Excellence in Agronomy, delivered in partnership with CIMMYT and the International Institute of Tropical Agriculture (IITA), Moises eagerly anticipates a bumper harvest in the early planted fields. She has been avidly implementing trials on planting dates to establish the implications of early, mid, and late planting on soybean yield. Let alone the required attention to detail, she exudes a deep understanding of the significance of the trials by carrying out key agronomic practices to ensure a good harvest. This will not only nourish the health and wellbeing of her family but also symbolizes the fruits of her dedication.
Moisesâs commitment extends beyond the trial she hosts as she implements her learning from the project to other fields, using innovative approaches like the double-row planting method. In soybean farming, this involves planting two rows of seeds on a wider ridge established on the traditional spacing that farmers use on maize. Traditionally, farmers in Angonia have been planting single rows of soybean on ridges spaced at 90 cm used for maize, thereby resulting in low soy plant populations and ultimately low yields. This different technique optimizes the plant population and land use efficiency, improving yields, and facilitating easier weeding.

Despite the promise of enhanced production, challenges persist. Southern Africa continues to face a growing demand for soybeans, with annual productivity of 861,000 metric tons (mT) falling short of the 2-million-ton demand. In Mozambique, vibrant soybean farms blanket the landscape, yet smallholder farmers like Moises grapple with underdeveloped markets and climate-related adversities, such as droughts and floods currently worsened by the El Niño phenomenon.
âAs a devoted soybean farmer, I have met my own fair share of challenges. One of our biggest challenges is the labor requirement across the production season,â shared Moises as she navigates through her fields. âWe need machinery for planting, weeding, and harvesting in order to reduce the labor and drudgery associated with soybean production. In addition, markets remain a challenge.” Her unwavering commitment inspires neighboring farmers, creating a ripple effect of hope and determination in the community.
Sharing the same sentiments is Veronica Ernesto Gama, who teams up with her husband every year to tend to her soybean field. Having started in 2007, their yields have sustained the food basket of her family while meeting nutritional needs. âIn the past, I used to just scatter around soybean seeds in one place, but after these trials, I have learned the significance of applying the agronomically recommended spacing and the need for quality improved seeds to ensure a bumper harvest,â said Gama.
The power of collaboration
Addressing these challenges head-on is CGIARâs Excellence in Agronomy Chinyanja Triangle Soy Use Case, a collaborative effort aimed at strengthening the soybean industry primarily by empowering farmers with improved agronomic practices and decision support. Solidaridad, an international non-government organization (NGO) pursuing digital platforms for scaling agronomy, serves as the demand partner of the Excellence in Agronomy Chinyanja Triangle Soy Use Case, while CGIAR provides technical support. Solidaridadâs role is vital in catalyzing demand for the product or service in question. Research outputs drawn from the trials will be used to develop a mobile phone application on the Kvuno, a social enterprise borne out of Solidaridad. The platform will support farmers with onsite advisories on planting dates, site-specific fertilizer recommendations, variety selection, and crop configurations.
To date, the initiative has drawn the willingness of 70 farmers in the Angonia district of Tete province, who are implementing different suites of trials, including nutrient omission, planting date, plant configuration, and fertilizer usage. Excellence in Agronomy has come at an opportune time for smallholdersâ journeys in soybean production, emphasizing the importance of optimized spacing and improved agronomic practices.
As the story unfolds in Mozambique, women like Moises and Gama are the unsung heroes driving soybean production. Their dedication, coupled with initiatives like Excellence in Agronomy, paint a picture of progress and potential. Their commitment inspires many surrounding farmers who draw inspiration on the trials in their fields. As the sun continues to rise over the dusty soils of Angonia, it showcases not just Moisesâs fields, but the bright future of soybean production in the hands of resilient women farmers.

Product design teams (PDTs) are a CGIAR Accelerated Breeding Initiative innovation created to address the aforementioned challenges under the CGIAR-NARES partnership through coordinating SPMS and related TPPs. Each seed product market segment, which in the case of CGIAR is defined at sub-regional level, represents a unique set of requirements. Attached to the segment is a TPP which describes the ideal product to meet the requirements. Taken together, the framework provides a starting point for discussions by breeding teams on investment opportunities.
Discussions on market segments and TPPs need to develop over time as new insights are gained. Some requirements might be overlooked, and others may be emerging due to client requirements and changes in the context. There is a need for a greater understanding of the evolving requirements of the seed companies, farmers, processors, and consumers in the market segments that CGIAR serves. It must be recognized that not all requirements of farmers or consumers are amenable to breeding or efficient to incorporate in breeding pipelines â for example, some post-harvest losses or weed management can be best addressed by appropriate storage mechanisms and improved agronomic practices, respectively.
Product design teams (PDTs) were created to address the aforementioned challenges under the CGIAR-NARES partnership by and coordinating SPMS and related TPPs. A PDT is a group of crop breeding and seed systems stakeholders for a particular crop, who work together to design or redefine TPPs. PDTs have been envisioned to be cross-functional teams that meet annually with the following aims:
Review the market segments at subregional and national levels, addressing critical questions, such as:
Do the subregional segments capture country-level requirements?
What is the opportunity for impact from breeding investments across market segments?
Are there important market segments that have not been captured?
What are the potential future segments that the team needs to consider?
Review and update TPPs for each segment, addressing questions such as:
Are any important traits missing?
Are country-specific trait values factored?
Are country-specific market-dominant varieties included in the market segment?
Discuss the needs for market intelligence for the PDT:
Unknowns regarding client requirements.
Gaps regarding product design parameters.
Director of the Global Maize program at CIMMYT, B.M. Prasanna, said, âPDT meetings serve as an important platform to understand the perspectives of diverse and relevant stakeholders. These discussions enable us to reach a common understanding of the current market requirements and redefine TPPs to reflect needs across value streams through co-creation and shared responsibility.â
The impact of PDTs
Pieter Rutsaert, seed systems specialist at CIMMYT and the CGIAR Market Intelligence Initiative, participated in several PDTs on maize and other crops, such as groundnut. âPDTs are a useful format to understand the unknowns in terms of farmer, processor, and consumer requirements and generate questions that guide future work in market intelligence,â said Rutsaert.

“PDTs will help in routine review of the product requirement for a specific country and will help to remove breeder bias and ensure that all stakeholdersâ views are heard and consideredâ, said Aparna Das, technical program manager for the Global Maize program at CIMMYT.
The main requirements for constituting PDTs for a specific country are:
A multidisciplinary team with 7 to 15 members, ensuring diversity of experience and providing reasonable time for decision-making.
Must consist of a range of stakeholders, such as: breeders from NARES (often the PDT convener/lead) and CGIAR; representatives of farmersâ groups, seed companies, and food processors; gender specialists; and market intelligence specialists.
30% of members should be female.
Should include a member from another crop breeding network, to bring a different perspective.
Bish Das, NARS coordinator, Dragan Milic, breeding specialist, and Lennin Musundire, breeding optimization specialist, from the CGIAR Accelerated Breeding Initiative team said, âUltimately, the client-led approach to priority setting that CIMMYTâs Global Maize program is implementing in southern and eastern Africa ensures strong alignment with partnersâ priorities and client requirements and better targeting of CGIAR regional maize breeding efforts.â
Case study: maize seed systems
CIMMYTâs Global Maize program has refined variety development to meet market needs across the value chain including farmers, processors, and consumers, thus enhancing variety adoption, which is the end goal of breeding pipelines. This has been implemented through the regional CGIAR-NARES-SMEs collaborative breeding networks and having âa bottom-upâ approach towards developing market segments and TPPs. This refers to building an understanding of end-users’ needs through inclusive in-country and regional stakeholder PDT meetings. PDTs also ensure that there are CGIAR-NARES-SME defined roles: a national mandate for NARES partners focusing on niche markets, the consolidated national mandate for CGIAR/NARES/SMEs, and a regional mandate for CGIAR Research Centers like CIMMYT.
In 2023, maize PDT teams were established and held meetings for five countries in eastern and southern Africa: Zambia, Ethiopia, Kenya, Zimbabwe, and Uganda. These meetings brought together stakeholders from different fields who play an important role in product development and seed systems (national partners and seed companies), varietal release (representatives from regulatory agencies) and end-product users (for example, millers).
The advantages of TDPs are emphasized by Godfrey Asea, director of Research and Daniel Bomet Kwemoi, maize breeder at the National Agricultural Research Organization (NARO) in Uganda. They highlighted that the NARO maize program has now begun a systematic journey toward modernizing its breeding program. The PDT team validated the countryâs market segments and aligned five product profiles with two major target production environments (TPEs), with the mid-altitude regions taking 85% of the maize seed market and the highlands accounting for 15%. âThese TPPs will be reviewed annually by the PDT since market segments tend to be dynamic. The breeding program has reclassified and aligned breeding the germplasm to TPPs, which will guide effective resource allocation based on the market shares,â said Asea.
Feedback on PDT meetings so far suggests positive experiences from stakeholders. Wendy Madzura, head of agronomy at SeedCo in Zimbabwe, said, âThe unique PDT meeting held at CIMMYT in Zimbabwe provided a conducive environment for public and private stakeholders to have meaningful and honest discussions on the current market segments and TPPs.â Plans for continuous improvement are embedded in the PDT model. âAs a follow-up to the PDT meeting, there is a need for further involvement of various stakeholders at the village, ward, and district levels to enable deeper insights and reach because the client needs are constantly changing,â said Madzura.
Recognizing that equitable access to finance and credit are key enablers for mechanization, this platform strived to understand smallholder farmer needs and the identification of key financing models to facilitate widespread adoption.
With over 40 participants ranging from government representatives, development partners, and stakeholders from organizations such as USAID, the Food and Agriculture Organization (FAO), the International Institute of Tropical Agriculture (IITA), the International Fertilizer Development Center (IFDC), and Hello Tractor, this regional event provided an opportunity for robust discussions and to align the course of action.
Unpacking mechanization in the Global South
Appropriate-scale mechanization is essential and a top policy priority to transform African agriculture. Evidence shows that nearly 70% of operations in sub-Saharan Africa are done manually. However, human labor is limited and is increasingly scarce and costly given the unfolding transformation of rural spaces in most places, necessitating agricultural mechanization. The cornerstone of this shift lies in integrating small, affordable machines tailored to the operations and needs of smallholder farmers, which must be accessible through market-based financial and business models.
A top policy priority in Zambia
The Permanent Secretary, Technical Services of the Zambian Ministry of Agriculture, Green Mbozi, officially opened the meeting. He lauded the meeting as timely and commendable as agriculture mechanization is a top policy priority for Zambia.

“The government has embarked on a process to formulate a national mechanization strategy, which will serve as a blueprint on how to sustainably promote agricultural machinery and equipment across the value chains. The insights from this workshop would be helpful in feeding into the formulation of the strategy and help in identifying entry points to support sustainable agriculture mechanization,â said Mbozi.
Accelerating change through inclusive dialogues
The dialogue played a crucial role in bolstering support for sustainable agriculture mechanization while tackling challenges hindering active adoption. Mbozi highlighted the imminent launch of an agricultural mechanization strategy developed with technical support from FAO and CIMMYT through the Sustainable Intensification of Smallholder Farming Systems in Zambia (SIFAZ) project.
The mechanization strategy champions sustainable and efficient mechanization practices, strengthens the private sectorâs role in mechanization, and provides training and financial support to small-scale farmers, women, and youth. Proposed initiatives include regional centers of excellence, a national mechanization association, and the use of information and communication technologies to promote mechanization.

âIt is important to develop the right bundle of mechanization services that meet the needs of farmers and are profitable for mechanization service providers,â said Director of Sustainable Agrifood Systems (SAS) at CIMMYT, Sieg Snapp. âFinding the right financing is needed to support multiple bundles of mechanization services, which provide profits throughout the year.â
Additionally, the SIFAZ project promotes local manufacturing, supporting quality assurance, conducting demand studies, and establishing an agricultural mechanization data bank to catalyze transformative progress.
Key insights from USAID and FAO
David Howlett, the Feed the Future coordinator at the USAID Mission in Zambia, shared with participants that, âUSAID is working to address the effects of climate change through mechanization and other adaptation strategies.â Aligning with the central focus of the meeting, he further reiterated that mechanization will be key to building resilience by improving agricultural systems.

Offering insights drawn from country-level experiences on scale mechanization for smallholder farmers, Joseph Mpagalile from FAO said, âFAO has been helping countries develop national agricultural mechanization strategies, with 12 countries in Africa already revising or preparing new strategies for sustainable agricultural mechanization.”
Private sector engagement: lessons from Hello Tractor
Operating across 13 African countries, Hello Tractor has been leveraging digitalization to scale mechanization in Africa since its inception. Hello Tractor facilitates services to over 500,000 smallholder farmers through 3,000+ tractors and combine harvesters, while providing remote tracking of assets and preventing fraud and machine misuse for machinery owners. At the heart of the company are booking agents who connect farmers to solutions to increase productivity and income.
Call to action
As the discussions ended, key outcomes distilled highlighted a pressing need to sensitize farmers on the merits of mechanization and facilitating access through tailored financial resources. Special attention was also directed towards empowering women and youth through implementation of de-risking mechanisms and strategic marketing linkages.
Recognizing the critical absence of data, a compelling call for a funding pool to collect essential information in the ESA region became clear. In addition, it was emphasized that appropriate-scale mechanization should be driven by sustainable business and financing models. The journey towards mechanization is a collective effort, blending policy initiatives, private sector engagement, and research-driven strategies.

In the ever-evolving field of agriculture, AGG-WHEAT is leading a transformative approach through rapid marker-selectable trait introgression in wheat breeding programs. This method aims to streamline the process of integrating desirable traits into various genetic backgrounds.
At the core of AGG-WHEAT’s strategy is the establishment of a centralized marker-selectable trait introgression pipeline. This initiative seeks to facilitate the transfer of specific genes from a centralized source into various genetic backgrounds within plant breeding programs. Molecular markers play a crucial role in efficiently identifying and selecting target traits.
The merits of a centralized trait introgression pipeline extend beyond convenience. This approach ensures a more uniform and controlled transfer of genetic material, enhancing the precision of trait introgressions across diverse breeding lines. Molecular markers streamline the selection process, improving the accuracy of desired trait incorporation into wheat varieties.
Speed breeding facilities in Toluca, Mexico
AGG-WHEAT’s marker-selectable trait introgression pipelines are implemented at the speed breeding facilities located at the CIMMYT research station in Toluca, Mexico. These facilities serve as the incubators for innovation, where new selection candidates are evaluated based on various criteria. The decision-making process involves an expert panel comprising geneticists, trait specialists, and breeders. This panel annually determines the selection candidates, considering factors such as trait demand, genetic diversity, evidence of Quantitative Trait Loci (QTL) effects, selection efficiency, and available funding.
The decision-making process involves a multifaceted evaluation of potential selection candidates. Documented trait pipelines and product profiles guide decision-making to ensure alignment with the overarching goals of wheat breeding programs. Considerations include the need for phenotypic variation and the existence of limited genetic diversity for the trait under consideration.
The decision-making process also explores existing in-house or external evidence of QTL effects and the underlying gene mechanisms. Selection efficiency, contingent on the availability of accurate molecular markers and a known purified donor parent, further refines the pool of potential candidates. Established phenotypic protocols for product testing and the crucial element of available funding complete the decision-making criteria.
Achievements
In a significant step towards innovation, the products of the first marker-selectable trait introgression pipelines entered yield trials in 2023. This marks a transition from conceptualization to tangible impact, reflecting the efficacy of AGG-WHEAT’s approach. A total of 97 F5-lines, cultivated through the marker-assisted backcross (MABC) scheme, now grace the fields.
These lines carry novel genes associated with fusarium head blight and rust resistance, derived from wheat genetic resources and wild relatives. The choice of these traits underscores AGG-WHEAT’s commitment to addressing challenges faced by wheat crops, ensuring improved resilience and sustainability in the face of evolving environmental conditions.
The success of these initial trait introgression pipelines represents more than a scientific achievement; it marks a pivotal moment in the trajectory of wheat breeding. The 97 F5-lines, standing as testaments to enhanced resistance traits, are poised to make a transition into mainstream breeding pipelines. This marks the commencement of a broader dissemination strategy, where these lines will be distributed for testing at National Agricultural Research and Extension Services (NARES).
The journey from the experimental fields to mainstream adoption involves a meticulous process. These lines, having undergone rigorous evaluation and selection, now hold the potential to catalyze changes in commercial wheat varieties. The lessons learned from their cultivation will shape future breeding strategies and contribute to the resilience of wheat crops in diverse agricultural landscapes.

The centralized approach, the strategic use of molecular markers, and the meticulous decision-making process exemplify the commitment to excellence and precision. The journey from concept to realityâmarked by the entry of 97 F5-lines into yield trialsâsignals a new era in wheat breeding.
As these lines traverse from experimental fields to mainstream adoption, they carry the promise of transforming the landscape of commercial wheat varieties. AGG-WHEAT’s lasting impact goes beyond the scientific realm; it extends to the fields where farmers strive for sustainable and resilient wheat crops. In the tapestry of agricultural progress, AGG-WHEAT has woven a thread of innovation that holds the potential to redefine the future of wheat cultivation.
In the dynamic landscape of wheat breeding, early access to germplasm emerges as a strategic catalyst for accelerating variety turnover and meeting the evolving challenges faced by farmers in South Asia. Since its inception, the Accelerating Genetic Gains in Maize and Wheat (AGG) project has pioneered new tools to optimize the wheat breeding process. One such tool, the efficient and low-cost 3-year breeding cycle, has been fine-tuned in Mexico, using the Toluca screenhouse and field advancement in ObregĂłn, laying the groundwork for faster variety turnover.
The inaugural set of lines generated through this enhanced breeding cycle is already undergoing Stage 1 trials in the ObregĂłn 2023-24 season. However, the innovation doesn’t stop there; to expedite the variety release process and garner robust data from the Target Population of Environments (TPE), Stage 2 lines are being rigorously tested at over 20 sites in South Asia through collaboration with National Agricultural Research and Extension Services (NARES) partners. In the seasons spanning 2021-2024, a total of 918 Stage 2 lines underwent rigorous trials, aiming to provide early access to improved wheat lines for testing and release by NARES and establish a genetic correlation matrix between ObregĂłn selection environments and diverse sites across South Asia.
These extensive trials serve a dual purpose. Firstly, they facilitate early access to improved wheat lines for testing and release by NARES, bolstering the agricultural landscape with resilient and high-yielding varieties. Secondly, they contribute to the establishment of a genetic correlation matrix between the selection environments in ObregĂłn and the diverse sites across South Asia. This matrix becomes a guiding compass, aiding in selecting the most promising lines for broader TPEs in South Asia and beyond.
Transformative impact on wheat varieties in South Asia
Through the support of our partners and funders from the Bill & Melinda Gates Foundation, the Foundation for Food and Agriculture Research (FFAR), the UK Foreign, Commonwealth & Development Office (FCDO), and the US Agency for International Development (USAID), great achievements have been recorded throughout the region. India, a prominent player in wheat cultivation, stands as a testament to the transformative impact of early access to advanced lines. The top three varieties, namely DBW187, DBW303, and DBW 222, covering over 6 million hectares, trace their roots to CIMMYT varieties. Adopting a fast-track approach through early-stage testing of these advanced lines at BISA sites in India, supported by the Delivering Genetic Gain in Wheat (DGGW) project, facilitated the release of these varieties two years ahead of the regular testing process. This expedited varietal release was complemented by the innovative early seed multiplication and dissemination approach introduced by the Indian Council of Agricultural Research (ICAR). Recent additions to this accelerated channel include varieties such as DBW 327, DBW 332, DBW 370, and 371, promising further advancements in wheat cultivation.
Pakistan
In Pakistan, the early access to advanced lines has been a catalyst for releasing high-yielding, climate-resilient, and nutritious wheat varieties. In 2023 alone, 12 new varieties were released, with the renowned ‘Akbar-19,’ introduced in 2019, covering a substantial 42% of cultivated land in Punjab. Data released by the Ayub Agricultural Research Institute (AARI), shows that this variety, known for its high yield potential, disease resistance, and enriched zinc content, has significantly contributed to increased wheat production in the region.
Nepal
Guided by policy interventions in the national varietal testing process, Nepal has experienced the fast-track commercialization of high-yielding and climate-resilient wheat varieties. Allowing multilocation testing of CIMMYT nurseries and advanced elite lines, Nepal released six biofortified zinc wheat varieties in 2020. The expeditious seed multiplication of these released and pre-release varieties has facilitated the rapid spread of new and improved wheat varieties.
The strategic utilization of early access to wheat germplasm in South Asia holds promise in accelerating variety turnover, offering farmers resilient and high-performing wheat varieties. Collaborative efforts between research institutions, government bodies, and international organizations exemplify the power of innovation in transforming agriculture. With an ongoing dedication to refining breeding cycles, expanding testing initiatives, and fostering collaboration, the AGG project contributes to building a sustainable and resilient agricultural future in South Asia. Early access to wheat germplasm emerges as a practical approach in this scientific endeavor, laying the foundation for a climate-resilient and food-secure region. The successes witnessed in India, Pakistan, and Nepal underscore the transformative potential of this approach, offering tangible benefits for agricultural communities in South Asia and beyond. In navigating the complexities of a changing climate and growing food demand, early access to wheat germplasm remains a pragmatic ally, propelling agricultural innovation and resilience to new heights.

Agriculture feeds the world. Yet traditional cycles of ploughing, planting, and harvesting crop and biomass products is inefficient of labor and other scarce resources and depletes soil health while emitting greenhouse gases that contribute to climate change.
One effort to ameliorate the negative effects of farming is a set of practices referred to as conservation agriculture (CA), based on the principles of minimal mechanical soil disturbance, permanent soil cover with plant material, and crop diversification.
To deliver advanced, high-level instruction on current innovative science around important aspects of cropping and farming system management to scientists from India, Bangladesh, Egypt, and Morocco, the 12th Advanced Conservation Agriculture Course hosted by the Indian Council of Agricultural Research (ICAR), CIMMYT, and the Borlaug Institute for South Asia (BISA) took place in India from December 10 to 24, 2023.
SK Chaudhari, deputy director general for Natural Resource Management, ICAR; HS Jat, director of the Indian Council of Agricultural Research-Indian Institute of Maize Research (ICAR-IIMR); Arun Joshi, country representative for India and BISA managing director, CIMMYT-India; Mahesh K. Gathala, senior systems agronomist and science lead, CIMMYT-Bangladesh; and Alison Laing, agroecologist, CIMMYT-Bangladesh, all attended the opening ceremony at the National Agricultural Science Complex in New Delhi, India.
This CA course integrated scientific advancements and multidisciplinary techniques to sustainably develop agricultural systems, restore natural resources, and improve climate resilience in agriculture throughout Asia and North Africa. It was held at leading research centers throughout India.
SK Chaudhari welcomed delegates to the course and stressed its practical character and efficacy in promoting CA management innovations, as evidenced by the significant achievements and international reputations of many former attendees and resource personnel.
âAs climatic variability and change increase, the need to manage agronomic risks grows, and CA is an effective tool for farmers and scientists in both irrigated and rainfed systems,â said Chaudhari.
Twenty rising scientists from such fields as agronomy, soil science, plant protection, agricultural engineering, plant breeding, and extension, took part in the workshop where they gained a better understanding of all aspects of conservation agricultural methods in rainfed and irrigated ecosystems, as well as exposure to wide networks with prominent international scientists. Organizers prioritized the inclusion of female scientists, who made up 40% of attendees.
The workshop empowered participants to act as conservation agriculture ambassadors and champions of modern, novel agronomic methods when they return to their home institutions.
Rajbir Singh, ICAR assistant director general for Natural Resource Management, and ML Jat, global research program director of Resilient Farm and Food Systems, International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) provided keynote addresses at the closing ceremony, held at the ICAR-Central Soil Salinity Research Institute in Karnal, Haryana, India.
