Spillover Increases Returns to Sorghum Genetic Enhancement

ICRISAT, in collaboration with national program partners in Asia and sub-Saharan Africa, assessed the spillover potential of sorghum varieties and hybrids across eight Sorghum Research Domains. The study demonstrated that cultivars originating from collaborative national and international research can prove highly transferable across different environments. The spillover of finished products, however, tended to be negatively correlated with national research capability: the stronger the national program, the lower the potential for the direct release of varieties and hybrids.
