Wheat breeding strategies for increased climate resilience

Wheat breeding strategies for increased climate resilience

With the challenges of climate change already affecting plant breeding, especially warmer days and warmer nights, the time to future proof the world’s food supply is now. In order to make the best-informed changes, scientists at CIMMYT ran simulations mimicking five scenarios that might play out over the next 70+ years.

The researchers used 3,652 breeding line records from six global nurseries administered by the International Wheat Improvement Network, which is coordinated by CIMMYT, and involves hundreds of partners and testing sites worldwide. Researchers ran the data through five different climate change scenarios, ranging from stable to severe.

Along with colleagues from Henan Agricultural University, Zhengzhou, China, ICARDA, and the Chinese Academy of Agricultural Sciences, CIMMYT scientists published their research in Nature Climate Change.

The results showed that less than one-third of wheat varieties adapted well to the warming the planet has already seen in the last 10 years. As temperatures increased in the simulation, researchers found a clear connection between rising temperatures and lower stability for a variety. As the global wheat-growing area becomes warmer and experiences more frequent heatwaves, breeding programs have to look beyond just yield optimization.

“Stability is key for breeding programs and farmers,” said co-lead author Matthew Reynolds, CIMMYT distinguished scientist and head of wheat physiology. “Knowing that a specific variety works well in a specific environment and produces an expected amount of yield allows farmers better plan their crop futures.”

“We performed the analysis from different perspectives, so that climate effects and appropriate adjustment suggestions for current breeding models can be considered from climate change, gene selection and/or gene–environment interaction perspectives,” said co-lead author Wei Xiong, CIMMYT Senior Scientist and Agricultural System Modeler.

The paradox of breeding elite lines

Local and regional breeding programs, as well as targeted breeding by CIMMYT, contribute to gene pools that overlap for many key agronomic traits, which limit genetic diversity.

“It is an unintended consequence,” said Reynolds. “As conventional breeding focuses on crossing the best and elite material, such focus can actually reduce genetic diversity.”

This ‘paradox’ shows the need to increase genetic variability and environmental diversification in breeding programs that are developing higher-yielding climate-resilient cultivars. Breeding programs also need to target traits associated with improved adaptation to increased temperatures and tolerance to heatwaves, which requires multidisciplinary integration.

Looking to the past for answers

Over the past 10,000 years, the climate has been unusually stable, meaning modern, domesticated bread wheat has not been exposed to wide swings in temperature that are forecast for the next 100 years. Wild wheat relatives, like Triticeae, have had millions of years of experience in weathering changing climates.

CIMMYT has a pre-breeding program that examines wild wheat races and more exotic sources for climate resilience traits. When such traits are identified genetically, new breeding techniques such as gene editing can be employed and breeding models refined.

To activate these new techniques, several barriers need to be overcome, including more sharing of germplasm between countries and breeding teams, the use of faster breeding cycles where appropriate and improved understanding of genes that improve heat tolerance without a yield penalty.

With reduced climate resilience and slow cultivar development, the need to increase genetic variability for climate adaptation is urgent, particularly in developing countries, where warming rate is unprecedented, and breeding cycles tend to be longer than in developed countries.

“Faced with more climate variability, breeders need to revisit their breeding strategies to integrate genetic diversity that confers climate resilience without penalties to productivity,” said Reynolds.

Innovation hubs in western Honduras, cornerstones for agricultural sustainability

Written by Julian Bañuelos-Uribe on . Posted in News.

We are paving the way for significant agricultural change in the community of Lentago, Belén Gualcho, Ocotepeque. By means of the AgriLAC Resiliente initiative, we have taken firm steps towards more sustainable and resilient agrifood systems in Honduras through continuation efforts at the agricultural innovation hub.

“Fertilization is one of the main issues identified through plot diagnosis and the participation of several producers from three areas (Lentago, El Aguacatillo and La Mohaga),” says Jesús Erardo Díaz Gómez. He is a technician participating in the project and provided Elmer Valeriano with technical support during the installation of the hub on his plot, where sustainable practices are currently being implemented and compared with conventional local practices.

Traditionally, fertilization occurs 15 to 22 days after planting. “The innovation hub seeks to improve this practice by evaluating fertilization during planting in order to ensure adequate nutrient availability maize plants,” says Erardo, who is part of the InnovaHub West Honduras technical team, which coordinates local organization and stakeholder AgriLAC Resiliente efforts, promoting innovation and sustainability in the Honduran agricultural sector.

InnovaHub Occidente is not just impacting fertilization methods. Erardo states that the seed selection processes for future crops also needs to be reexamined. Currently, seeds are selected once they “tapizcan” (harvest) the maize, taking it out of the field. However, this has its problems. “With the innovation hub, we aim to start this process in the field, carefully selecting the healthiest plants most suited to the needs of local producers,” he explains.

Hubs like the one in Lentago help disseminate knowledge about sustainable practices. The CIMMYT and ODECO technical team has played a pivotal role resolving questions and orienting farmers about sustainable maize management.

Of course, the success of efforts like this one requires commitment and active participation from farmers like Elmer Valeriano. Elmer is a proactive farmer open to new techniques. He is an inspirational model showing how collaboration between technicians and farmers drive the shift towards more sustainable and efficient practices, like the installation of a rain gauge that promises to yield vital data for informed decision making in the hub.

Though seemingly simple, the rain gauge provides a way to better understand crop irrigation requirements and adjust agricultural practices accordingly. “The results will allow us to compare the amount of water received with actual crop requirements, providing a reliable foundation for making decisions,” says Erardo, noting Elmer’s commitment to collecting and recording the data from the rain gauge.

The work by InnovaHub Occidente de Honduras is not isolated. It is a part of a broader initiative: AgriLAC Resiliente. This CGIAR driven effort aims to transform agrifood systems in Latin America and the Caribbean by increasing resilience and competitiveness. The InnovaHubs in Honduras, in collaboration with organizations such as the Alliance of Bioversity International and CIAT and CIMMYT, are paving the way towards a more prosperous and sustainable future for agriculture in the region.

Ultimately, success for these initiatives will depend on continued collaboration among all stakeholders: farmers, technicians, organizations, and local communities. More resilient agrifood systems that not only feed present generations, but also protect and restore land for future generations, are possible as long as we continue to focus on innovation and sustainability.

Revised market segmentation for spring wheat—achieving alignment between ICARDA and CIMMYT

Written by dmedina on . Posted in In the media.

CIMMYT, in collaboration with ICARDA and the CGIAR Initiative on Market Intelligence, has revised the market segmentation for spring wheat to align breeding efforts using a unified “crop view” approach. This initiative resolves duplication challenges, provides objective crop prioritization, and aligns Target Product Profiles (TPPs) to meet the needs of farmers, consumers, and processors. By establishing a consistent application of eight market segmentation criteria, the effort standardizes the process and lays a foundation for future discussions on market segment prioritization and TPP alignment, ensuring all relevant market requirements are prioritized in breeding programs.

Cultivating healthier communities with provitamin A maize varieties

Written by Julian Bañuelos-Uribe on . Posted in Publications.

In Murehwa District, situated in Zimbabwe’s grain basket in the eastern part of the country, vitamin A deficiency is prevalent in almost all households, regardless of their wealth, reveals a study striving to quantify the nutritional yields of provitamin A maize across a diverse range of smallholder farms in Zimbabwe and to understand the potential role of improved agronomy in increasing nutritional yields. Published in the Journal of Nutrition, the study is part of a collaborative project between CIMMYT and Rothamsted Research, funded by the UK Global Challenges Research Fund, administered by the Biotechnology and Biological Sciences Research Council.

The study revealed that vitamin A deficiency is most prevalent in the wet seasons when the number of people within a household is higher. Using a range of realistic provitamin A concentration levels, modelling showed that the consumption of provitamin A maize could ensure that almost three-quarters of households reach 50% of their vitamin A requirement.

“This study highlights how provitamin A maize could make a real difference in vitamin A intake of smallholder farmers in rural areas of Zimbabwe,” said Frédéric Baudron, the lead author of this study. “And the impact could be even higher as greater gains are made through breeding and supported by better agronomy, a key determinant of nutrient concentration in the grain produced.”

Thirty households participated in the study, quantifying the composition of their diet across the main agricultural (wet) season and off (dry) season. A market study of locally available food was also conducted at the same time. In Murehwa District, almost 80% of the population is engaged in small-scale agriculture as their primary livelihood and stunting rates have increased over the past decade in this district, in sharp contrast to the rest of Zimbabwe.

Though maize is a dietary staple widely consumed in various forms in Zimbabwe, vitamin A deficiency exerts a heavy toll on people’s health, particularly in rural communities where its impact is most keenly felt. The consequences, ranging from preventable blindness in children to heightened maternal mortality rates and reduced immune function, emphasize the urgency of sustainable interventions.

The first provitamin A maize variety was released in Zimbabwe over a decade ago. Subsequent breeding efforts, aiming to develop varieties capable of providing 50% of the estimated average requirement of vitamin A, have focused on increasing the provitamin A concentration in maize and yields obtained under a range of stresses that farmers frequently encounter. To date, 26 provitamin A varieties have been released in Southern Africa. However, several key research questions remained unanswered. For instance, how prevalent is vitamin A deficiency within vulnerable populations and what is the cost of an affordable diet providing enough vitamin A? Furthermore, can the nutritional concentration of provitamin A maize grown by smallholder farmers help significantly decrease vitamin A deficiency for the majority of rural households?

The nutritional concentration of biofortified crops is related to the environment they are grown in. Biofortified maize primarily targets resource-poor farmers, holding potential in addressing nutritional gaps. However, existing research on the potential health outcomes of the consumption of provitamin A has largely been centered on maize grown in controlled environments, such as on experimental research stations or commercial farms.

The CIMMYT-led study concludes that the consumption of provitamin A maize alone would not fully address vitamin A deficiency in the short-term, calling for additional interventions such as diet diversification, industrial fortification, and supplementation. Diet diversification is one viable option highlighted by the study: modelling showed most households could obtain a diet adequate in vitamin A from food produced on their farms or available in local markets at a cost that does not exceed the current cost of their diets.

In Murehwa District, the CIMMYT-led study estimated the daily costs of current diets at USD 1.43 in the wet season and USD 0.96 in the dry season. By comparison, optimization models suggest that diets adequate in vitamin A could be achieved at daily costs of USD 0.97 and USD 0.79 in the wet and dry seasons, respectively. Another study conducted in 2023 showed that almost half of the farms in the district had knowledge of PVA maize and its benefits but did not grow it, primarily due to a limited availability of seed.

Harnessing new high-resolution satellite imagery to plant breeding

Written by Julian Bañuelos-Uribe on . Posted in Publications.

In plant breeding, efforts to increase the rate of genetic gains and enhance crop resilience to the effects of climate change are often limited by the inaccessibility and costs of phenotyping methods. The recent rapid development of sensors, image-processing technology and data analysis has provided new opportunities for multiple scales phenotyping methods and systems. Among these, satellite imagery may represent one of the best ways to remotely monitor trials and nurseries planted in multiple locations, while standardizing protocols and reducing costs.

This is because relevant data collected as part of crop phenotyping can be generated from satellite images. For instance, the sensors onboard the SkySat satellite constellation of Planet Labs have four spectral bands—blue, green, red, and infrared—which can be used to calculate the normalized difference vegetation index (NDVI), which is a measure of vegetation and its greenness, and various canopy traits like ground cover, leaf area index and chlorosis. It can also be used to monitor plot establishment and phenological parameters.

The use of satellite-based phenotyping in breeding trials has typically been restricted by low resolution, high cost and long intervals between fly-overs. However, the advent of a new generation of high-resolution satellites—such as the SkySat constellation—now offers multispectral images at a 0.5m resolution with close to daily acquisition attempts on any place on Earth. This could be a game changer in terms of the scale at which yield trials can be conducted, enabling more precise variety placement and thereby increasing genetic diversity across farmer’s fields and reducing the probability of disease epidemics. It could also revolutionize the capacity for research in realistic field conditions, since traits can be measured throughout the cycle in a highly standardized way, over multiple sites at low cost. For example, an image which covers 25 km2 can monitor an entire research station at a cost of about US$300.

To test the suitability of this technology, a team of researchers from CIMMYT set out to evaluate the reliability of SkySat NDVI estimates for maize and wheat breeding plots of different sizes and spacing, as well as testing its capacity for detecting seasonal changes and genotypic differences.

Both their initial findings, recently published in Frontiers in Plant Science, and more recently acquired data, show that the SkySat satellites can be used to monitor plots commonly used in wheat and maize nurseries. While wheat yield plots usually are 1.2m wide, maize plots tend to consist of at least two rows, resulting in a width of 1.5m. Plot length ranges from 2-4m. The authors also discuss on other factors to be considered when extracting and interpreting satellite data from yield trials, such as plot spacing.

Through the successful collection of six satellite images in Central Mexico during the rainy season and parallel monitoring of a maize trial in Zimbabwe, the researchers demonstrate the flexibility of this tool. Beyond the improvement of spatial resolution, the researchers suggest that the next challenge will be the development and fine-tuning of operational procedures that ensure high quality, standardized data, allowing them to harness the benefits of the modern breeding triangle, which calls for the integration of phenomics, enviromics and genomics, to accelerate breeding gains.

CIMMYT is pleased to announce the release of a set of 32 new CIMMYT maize lines (CMLs). These maize lines have been developed by CIMMYT’s Global Maize Program by a multi-disciplinary team of scientists in sub-Saharan Africa, Latin America, and Asia. The lines have diverse trait combinations and are suitable for the tropical/subtropical maize production environments targeted by CIMMYT and partner institutions.

CMLs are freely available to both public and private sector breeders worldwide under the standard material transfer agreement (SMTA).

CIMMYT seeks to develop improved maize inbred lines for different product profiles, with superior yield performance, multiple stress tolerance, and enhanced nutritional quality. CMLs are released after intensive evaluation in hybrid combinations under various abiotic and biotic stresses, besides optimum (non-stress) conditions in the target population of environments. Suitability as either female (seed) or male (pollen) parent is also evaluated. As done in the last announcement of CMLs in 2021, to increase the utilization of the CMLs in the maize breeding programs of the partner institutions, all the new CMLs are tested for their heterotic behavior and assigned to specific heterotic groups of CIMMYT: A and B.

The release of a CML does not guarantee high combining ability or per se performance in all the environments; rather, it indicates that the line is promising or useful as a parent for pedigree breeding or as a potential parent of hybrid combinations for specific mega-environments. The description of the lines includes heterotic group classification, along with information on their specific strengths and their general combining ability with some of the widely used CMLs or CIMMYT coded lines under different environments.

More information:

Kenya Agricultural and Livestock Research Organization (KALRO)’s research station at Kiboko, Kenya, where several partner institutions including the International Maize and Wheat Improvement Center (CIMMYT), conduct significant research activities on crop breeding and seed systems, is now equipped with five new seed drying machines along with a dedicated shed to house these units, a cold room for storing breeding materials, and an additional irrigation dam/reservoir. These infrastructural upgrades are worth approximately US $0.5 million.

During the commissioning of the new facilities on February 7, 2023, CIMMYT Global Maize Program Director, BM Prasanna thanked the donors, Crops to End Hunger (CtEH) Initiative and Accelerated Genetic Gains (AGG) project, that supported the upgrade of the research station, and recognized the strong partnership with KALRO.

“Today is a major milestone for CIMMYT, together with KALRO, hosting this center of excellence for crop breeding. This facility is one of the largest public sector crop breeding facilities in the world, with hundreds of hectares dedicated to crop breeding. These new facilities will enable CIMMYT and KALRO crop breeders to optimize their breeding and seed systems’ work and provide better varieties to the farming communities,” said Prasanna.

Kenya suffered one of its worst droughts ever in 2022, and the newly commissioned facilities will support expedited development of climate-resilient and nutritious crop varieties, including resistance to major diseases and pests.

Improvements and enhancements

The efficiency of the seed driers capabilities to quickly reduce moisture content in seed from above 30% to 12% in two to three days, reducing the time taken for seed drying and allowing for more than two crop seasons per year in a crop like maize.

The additional water reservoir with a capacity of 16,500 cubic meters will eliminate irrigation emergencies and will also enhance the field research capacity at Kiboko. Reliable irrigation is essential for accelerating breeding cycles.

At the same time, the new cold room can preserve the seeds up to two years, preventing the loss of valuable genetic materials and saving costs associated with frequent regeneration of seeds.

World-class research center

“The Kiboko Research Center is indeed growing into an elite research facility that can serve communities in entire sub-Saharan Africa through a pipeline of improved varieties, not only for maize but in other important crops. This will not only improve climate resilience and nutrition, but will contribute to enhanced food and income security for several million smallholder farmers,” said Prasanna.

KALRO Director General Eliud Kireger appreciated the establishment of the new facilities and thanked CIMMYT and its partners for their support.

“Today is a very important day for us because we are launching new and improved facilities for research to support breeding work and quality seed production. This research station is in Makueni County, a very dry area yet important place for research because there is adequate space, especially for breeding,” said Kireger. “We are significantly improving the infrastructure at Kiboko to produce and deliver better seed to our farmers.”

For more than three decades, CIMMYT has conducted research trials at the Kiboko Research Station, focusing on drought tolerance, nitrogen use efficiency, and resistance to pests and diseases, such as fall armyworm and stem borer. The maize Double Haploid (DH) facility established in 2013 at Kiboko, with the support of the Bill & Melinda Gates Foundation, offers DH line production service for organizations throughout Africa, and is key to increasing genetic gains in maize breeding.

Five strides forward for CGIAR crop breeding resources and services

Written by Sarah McLaughlin on . Posted in News.

Sitting at the cutting edge of science, the crop breeding domain has been improving and refining tools, technologies and techniques. But adoption by public breeding programs focusing on Africa, Asia, and Latin America has often been slow. This has hindered progress on developing the new varieties needed for farmers to overcome climate impacts, build livelihoods, and feed their communities.

But One CGIAR’s new integrated approach is changing that. Building on the work of CGIAR Excellence in Breeding, the Breeding Resource Initiative can point to major progress in 2022, moving forward on an array of shared services, capacity development programs and technical support. Here are five significant milestones helping CGIAR and its national partners deliver better results:

1. Regional hubs are on their way: CGIAR’s vision is to have regional hubs coordinating and delivering services across crops. AfricaRice is set to grow into a regional service provider and coordinator for multiple crops in West Africa. After discussions, planning and site visits with BRI, AfricaRice leadership committed to working with the BRI team to start by providing regional nutritional analysis services, aimed to launch for selected partners in 2023. The plan is to then expand AfricaRice’s role as a coordinator of other competitive services like genotyping and capacity building. This is a major step toward CGIAR’s vision of not just improving breeding stations, but serving  all CGIAR/National Agricultural Research and Extension Services (NARES) partners regionally. The aim is collaboration, efficiency and results in farmers’ fields.

2. Operations teams are amping up skills and knowledge: Breeding success hinges on good operational practices leading to accurate data. To ensure the heritability of breeding trials, BRI has offered resources, trainings and on-the-ground support for operational teams. Through its Breeding Operation Network for Development (BOND), BRI/EiB, along with IITA, ran three weeklong workshops for partners across Africa (watch all 22 sessions on plotmanship, gender, seed processing, irrigation and more), regular webinars exploring private and public sector best practices, and a series focusing on continuous improvement approaches. BRI also trained dozens of operational staff across Africa on how to use and maintain new USAID-supplied equipment. And CGIAR continued its push to harmonize rice breeding processes between IRRI, AfricaRice and CIAT through a week-long rice breeding operations training at IRRI. As well, new tools such as a gender inclusion checklist are now available to support operational excellence.

3. EBS is settling in as a universal data platform: The data management platform Enterprise Breeding System has made real strides in the past year, with an updated version with new features (Milestone 5) rolling out across three Centers (CIMMYT, IITA, IRRI), with over 500 users. Other Centers, such as AfricaRice are starting to deploy the system too. On their visit to AfricaRice’s Ivory Coast station, the BRI team noted barcode deployment across the upland rice nurseries – an inspiration to spur other CGIAR Centers to accelerate their own adoption. EBS is a single, powerful, shared, multi-crop platform and its deployment will mean major time and money savings for breeders – and better breeding decisions.

4. Lab services are expanding: As breeders strive for higher-yielding, climate-resilient and nutritious crops, BRI/EiB have been improving breeding speed and accuracy through streamlined, reliable and cost-effective genotyping services. Services include Low Density SNP Genotyping Services (LDSG), Mid-density SNP Genotyping (MDSG), along with training. BRI also launched a Lab Services Process Team to connect Genetic Innovation departments and teams and ensure delivery of high quality services through standardized processes. And launching in 2023, partners will be able to access biochemical testing for nutritional traits and quality. These improved services mean CGIAR and national partners are becoming more effective and competitive as they use this data to make better decisions.

5. Regional approaches set to drive change: BRI drives change at both local and regional levels. For example, team members visited Kiboko and Njoro stations in Kenya, and ran planning sessions in Nairobi with East African breeding teams. This helped clarify challenges and priorities in the region, helping define how services could best be established. Kenya’s key outcomes included: a commitment with CIMMYT leadership to establish services in Kiboko as a pilot, an action plan to improve EBS development and adoption in the region, and endorsement by CGIAR Breeding Research Services leadership of major Crops to End Hunger grants in the region – these fill key gaps in the drive to modernization. The team plans to organize similar sessions to support CGIAR/NARES breeding networks in other regions.

These five strides forward represent but a glimpse into Breeding Resources’ progress. And these are much more than just separate achievements. They represent a shift in breeding culture across the CGIAR-NARES networks – one that will help deliver better varieties, faster. With major plans for 2023, CGIAR-NARES can look forward to the tools and services they need to deliver first-class programs.

Plant breeding must adapt to climate change, finds study

Written by Sarah McLaughlin on . Posted in Publications.

Breeding is a vital part of the global agrifood system, enabling scientists to adapt crops to developing environmental factors, support improved crop management, and inform policy interventions on global food production. The challenge to crop breeding increases every year, as farmers experience more of the effects of climate change, while the population and food demand continue to rise.

Research by the International Maize and Wheat Improvement Center (CIMMYT) has determined that climate change is affecting the objectives, efficiency, and genetic gains of current plant breeding, causing limitations to the breeding approach of the next generation.

The study found that climate change necessitates a faster breeding cycle and must drive changes in breeding objectives by putting climate resilience as the top priority.

“The risk of multiple crop failure due to climate change is very real. Breeding must become more deterministic in terms of adaption if we are to avert food price-hikes, hunger, and social unrest,” said Matthew Reynolds, Distinguished Scientist and Head of Wheat Physiology at CIMMYT.

Challenges in developing climate-ready crops originate from the paradox between urgent breeding requirements prompted by climate change and the limited understanding of how different genotypes interact with the climates. Integrating multiple disciplines and technologies including genotyping, phenotyping, and envirotyping can contribute to the development and delivery of climate-adapted crops in a shorter timeframe.

The Accelerated Varietal Improvement and Seed Delivery of Legumes and Cereals in Africa (AVISA) project has developed draft national groundnut target product profiles in Malawi, Mozambique, Sudan, Tanzania, Uganda and Zambia.

Groundnut is grown in eastern and southern Africa, where it remains an important food and oil crop from small holder farmers.

The new findings from the project are a result of work from groundnut crop breeding and improvement teams from the National Agricultural Research and Extension Systems (NARES) representatives from the six largest groundnut producing countries in the eastern and southern Africa region.

Their important research was carried out with the support of representatives from the Centre for Coordination of Agricultural Research and Development for Southern Africa (CCARDESA) and CGIAR.

Developing target product profiles for groundnut

For the first time, through the International Maize and Wheat Improvement Center (CIMMYT)-led AVISA program, funded by the Bill & Melinda Gates Foundation, groundnut breeding teams discussed and documented country level priorities at a meeting in Dar es Salaam, Tanzania.

Their findings were developed using a standard target product profile template recently developed by CGIAR Excellence in Breeding (EiB) in conjunction with CGIAR’s Market Intelligence Initiative. The template serves as a tool to capture market segments and develop targeted product profiles.

The groundnut breeding teams also shared information on current groundnut production metrics and trends in the six national programs. This also helped to establish a common understanding of countries’ level research priorities.

Agnes Gitonga, market strategist at CGIAR Genetic Innovations Action Area, who led the team in understanding and applying the template, explained that the quality of a target product profile (TPP) is dependent on how well market segments are defined. “To ensure target product profiles are an accurate reflection of customer needs, who include farmers, consumers, and processors,” she said.

“National groundnut teams nominated Country Product Design Teams that will meet nationally before the end of 2022 to review and update country TPPs. These multi-stakeholder teams will ensure that the needs of diverse groups are captured and that breeding efforts are accurately focused.”.

Harish Gandhi, Breeding Lead, Dryland Legumes and Cereals (DLC) at CIMMYT, further explained that a bottom-up approach for defining country and regional priorities was used, where each country defined market segments and target product profile based on the use of the produce and growing conditions of farmers. This strategy involved each country defining its market segments and TPP, which was based on the use of the produce and growing conditions of farmers.

Building on the draft national target product profiles that were defined at the meeting, participants went on to prioritize traits such as diseases, nutrition and stress tolerance. These factors can be critical at regional level and important in identifying potential locations for conducting phenotyping. The phenotyping locations are distributed based on capacity of stations in different countries to screen for traits, such as late leaf spot disease screening in Msekera in Zambia, which is a known hotspot for the disease.

“We had a good opportunity to consider grower needs as well as consumer needs in each country for purposes of defining the relevant groundnuts market segments. I believe this will have a positive impact on future work in groundnuts in the East and Southern Africa region,” reflected Gitonga.

The collaboration of the teams involved was a key factor for the project’s success so far and will be crucial in working towards its goals in the future.

“Involving different stakeholders in designing target product profile was an effective way of enabling transformation of individual preferences (area of interest) to collective preferences (targeted product) with consumer needs and markets in mind,” said Happy Daudi, Groundnut Breeding lead at the Tanzania Agricultural Research Institute (TARI).

Strengthening groundnut breeding programs in east and southern Africa

The project’s first meeting will provide an important foundation for future research, which will use the new findings as a blueprint.

Biswanath Das, Plant Breeder, Groundnut for East and Southern Africa region and NARES Coordinator and Programming lead for EiB said, “Defining national TPPs, identifying regionally important traits and mapping a testing network are fundamental building blocks of a modern breeding program.”

At the meeting, a schedule was laid out for peer-to-peer assessments of breeding programs within the regional network to take stock of current efforts and gaps. This step helps to develop customized capacity development plans for each network partner.

“Through targeted and demand led capacity development, the East and Southern Africa groundnut crop improvement network aspires to strengthen the role of each network member in collaborative, regional breeding efforts,” Das said.

The meeting laid the ground for coordinated regional groundnut breeding and took steps towards formalizing a regional NARES-CGIAR-SME groundnut crop improvement network. By building on excellent connections that already exist among national groundnut breeding teams. Das underscored that the move will strengthen alignment of NARES, CGIAR and regional research efforts around a common vision of success.

In addition, David Okello who leads groundnut research at National Agriculture Research Organization (NARO) Uganda, noted that the meeting provided a good opportunity for consolidating the existing network. He also looked forward to welcoming more groundnut improvement programs in the region on board.
