This project aims to discover alleles that contribute to sorghum drought tolerance through comparative genomics. The project has several partners from universities and research institutions in Ghana, India, Sudan, and the US. It involves evaluating combinations of "staygreen" genes that enhance terminal drought tolerance in improved sorghum varieties. It also tests relationships between drought tolerance and specific genes and functional SNPs. Field studies include producing crosses to isolate QTLs. The project has generated staygreen lines with one- and two-QTL combinations, an RIL population, transcriptomes, SNPs, and capacity building through training.
