New common bean genotypes to confront drought
Drought affects 60% of the bean-producing regions, and is responsible for total crop failure in the worst-case scenario. But this fight is not lost as demonstrated by 13 new bean genotypes developed by scientists of CIAT’s Bean Program using interspecific crosses. The work was done in close collaboration with the Autonomous University of Barcelona (UAB), with the support of the Bill & Melinda Gates Foundation (BMGF) and CGIAR Research Program on Grain Legumes.
This output resulted from several years of work aimed at achieving a better understanding of the physiological basis of improved drought resistance in common bean. A major lesson learned from this work is that no single morpho-physiological trait stands out for its unique and dominant contribution to drought resistance in common beans.
