Abstract

Sorghum is an important food security crop in sub-Saharan Africa, including eastern Africa but grain yields are very low. This is due to the many stresses it goes through during production in addition to use of unimproved genotypes. The objective of this project was to select, develop and promote sorghum lines that can withstand both abiotic and biotic stresses prevalent in eastern Africa. Sorghum genotypes were collected, lines developed and tested against various stresses, and data collected and analysed. Many genotypes adapted to the various stresses have been developed. Some lines have been submitted for variety release process including Nyadundo 1 and Nyadundo 2, MCSRV E94, MCSR N4, which are drought tolerant, Striga tolerant and can withstand some of the diseases.
