Abstract:
The experimental material consisted of ten inbred lines, their 45 F1s developed through diallel mating excluding reciprocals, were evaluated in Randomized Complete Block Design with three replications. The analysis of variance for combining ability revealed that mean squares due to both GCA and SCA were significant for all the characters except SCA for oil content, indicating the importance of both additive and non-additive gene action for the inheritance of studied characters. The estimates of σ2gca were higher than the corresponding σ2sca for effective length of primary raceme and oil content indicated the preponderance of additive component of genetic variance for these traits, while for number of capsules on primary raceme, number of effective branches per plant, shelling out turn, 100-seed weight and seed yield per plant non-additive component of genetic variance was predominant. Parents, PCS-124, SKI-215 and JI-35 were good general combiners for seed yield per plant and other yield contributing characters. Hybrids, SKP-84 x PCS-124, VP-1 x SKI-346 and SKP-84 x JI-35 had high per se performance, high heterotic effects and desired sca effects for seed yield per plant and its component characters.
