The problem of conferring resistance to grain deterioration in early maturing kharif season sorghums has been further examined. Tan plant type, hardness of grain and water absorption rate together furnish useful criteria for breeding resistant types. The inheritance of hardness of seed and rate of water absorption are predominantly additive and selection for these characters could be effective. Hard × hard crosses within tan types are likely to yield quick results. The male steriles 296A, 2277A and 2947A, the males CSV-4 (CS 3541) and CSV-5 (168) and amongst germplasm materials ESGPG-35, an African zerazera, are identified as most promising materials resisting grain deterioration.
