AVISA
The Accelerated Varietal Improvement and Seed Delivery of Legumes and Dryland Cereals in Africa (AVISA) project increased demand-driven, gender-equitable and timely access to quality seeds and inputs for small-scale producers by strengthening links between seed producers, farmers and grain aggregators, particularly women and young farmers.

Brief description
'Accelerated Varietal Improvement and Seed Systems in Africa (AVISA)' focused on modernizing and streamlining breeding programs to deliver climate-resilient, market-preferred and nutrient-dense crop varieties. In the context of increasing climate variability, declining productivity, and changing consumer demands, many national breeding programs face challenges such as outdated testing pipelines, inefficient data management and limited resources.
AVISA addresses these gaps by linking test sites to the 'target population of environments' (TPE) to ensure varieties are tested under farmer-relevant conditions. It strengthens early and late generation testing pipelines to accelerate the identification and release of superior varieties. A unique aspect of the project is the integration of digital tools, including the Breeding Management System (BMS) for efficient data collection, analysis and decision-making.
Additionally, AVISA introduced breeding program costing frameworks to optimize resource allocation and sustainability. By combining modern breeding strategies, capacity building, and data-driven approaches, AVISA is transforming traditional breeding pipelines into next-generation systems that deliver improved varieties faster, meeting the needs of farmers, markets and consumers across sub-Saharan Africa.
Key Achievements
Test sites linked to target population of environments (TPE)
- Complied historic data for Ethiopia and Uganda to establish a robust network of testing sites strategically linked to the Target Population of Environments (TPE) to ensure that variety development is demand-driven and responsive to farmers’ needs
- Strengthened partnerships with National Agricultural Research Systems (NARS) and regional breeding networks, enabling multi-location trials that capture key production constraints and market class preferences
- Improved environmental characterization and data-driven site selection to enhance the accuracy of variety performance prediction
Early-generation testing (EGT)
- Streamlined early-generation testing to increase the efficiency of identifying promising breeding lines
- Introduced rapid cycling and high-throughput phenotyping approaches, allowing faster advancement of elite lines
- Enhanced decision-making through better trial designs and data management, leading to quicker identification of high-potential lines for subsequent testing stages
Late-generation testing (LGT)
- Strengthened late-generation testing pipelines to ensure reliable evaluation of advanced lines under farmer-relevant conditions using TRICOT.
- Multi-location trials across diverse environments to assess yield stability, cooking quality, nutritional value (e.g., iron and zinc), and resistance to major biotic and abiotic stresses through PABRA regional trialing
- Supported variety release processes by generating robust datasets for national performance trials and registration
