The development of staygreen genotypes through hybridization is an important food security strategy in the semi-arid tropics. This study used 36 sorghum synthetics obtained from a 6 x 6 full diallel mating design. The parents, F1 progenies and their reciprocals showed significant difference for days to flowering suggesting their diversity with regard to this triat. There were significant differences among the maternal and non-maternal effects implying that maternal genes play a greater role in regulating maturity. There were higher genetic predictability ratios for days to flowering, panicle weight and grain weight
