Improving cassava yield in Africa's drought-prone environments
This project expands on earlier work to map genes responsible for cassava mosaic disease (CMD) resistance by identifying additional sources for resistance to CMD, as well as to other biotic stresses. It also incorporates a cassava breeders’ community of practice (CoP) that focuses on the application of molecular breeding for variety development. This effort is spearheaded by Nigeria's National Root Crops Research Institute (NRCRI) in collaboration with other country programmes in Ghana, Tanzania and Uganda, as well as CIAT and IITA.
The project also focuses on drought tolerance. Borrowing from the development of a new marker-assisted recurrent selection (MARS) approach for other crops, MARS for cassava will be implemented in Nigeria and Ghana.
Marker–trait association to enhance breeding efficiency through QTL mapping for pest and disease resistance, and stacking of favourable alleles affecting yield and yield components, particularly under water-limited environments.
