Abstract
A random-mating population of sorghum (Sorghum bicolor (L) Moench) Y composite, was being improved for yield using recurrent mass selection. After two cycles, CO, Ct , and C; were evaluated in Samaru and Mokwa in 1983 season. Phenotypic and genotypic variances and correlations of the yield components were studied. Mean squares between locations were highly significant for all traits except count at thinning and panicle width. Highly significant mean squares for the generations were recorded for all traits, except panicle width and number of grains per panicle. Non-significant genotype X environment interaction mean square were observed for all traits except days to 50% flowering which showed a highly significant (P S 0.01) mean square generally, all traits were positively correlated, with days to 50% flowering being highly correlated with all traits except count at emergence.
