Combining ability studies in 10 parental genotypes and their half diallel set revealed the predominant role of nonadditive gene action for the characters viz., days to 50 per cent flowering, days to maturity, number of primary branches, number of secondary branches, capsules on branches (primary and secondary), capsules per plant and seed yield per plant. The direction and magnitude of gca and sca effects indicated RT 54, VS 16 and R B4-4-2 at the best general combiners and the crosses RT 54 x X 198, VS 16 x AT 3, JLT5 x Madhavi and JLT 5 x JLT 6 as the best F3 combinations for some of the characters studied.
