Study on combining ability effects were carried out in 28 hybrids obtained by crossing 8 x 8 genotypes in half diallel fashion and parents, hybrids evaluated with standard check Maharaja in RBD with three replication during kharif2018-19 at research farm of Agriculture botany College of Agriculture, Latur for twelve traits viz., days to 50 per cent tasseling, days to 50 per cent silking, days to maturity, plant height (cm), ear length (cm), ear girth (cm), kernel row number, number of grains per row, 100-grain weight (g), fodder yield per plant (g), grain yield per plant (g) and Harvest index (%). The analysis of variance revealed that significant differences among treatments, parents, hybrids and parents v/s hybrids for all characters except days to 50 per cent tasseling and days to 50 percent silking. This validated that, considerable amount of variability among experimental material. The combining ability analysis revealed the presence of higher magnitude of SCA than GCA variance for all characters under study. The ratio of additive to dominance variance was lower than unity for all traits, indicating higher non-additive variance than additive variance. Among parents, 231-A, Hyd.19051 and Hyd.19051 was found to good general combiner for grain yield per plant. While the parent 231-A exhibited good general combining ability for majority of characters. Best specific combinations were Hyd.18227 x Hyd.08R-740-2, Hyd.19051 x Hyd.12288, Hyd.18227 x Hyd.18169 and Hyd.18063 x Hyd.18169 for grain yield per plant.
