Combining ability analysis in Indian mustard (Brassica juncea L. Czern & Coss)

Combining ability analysis of 10  10 diallel set of crosses in Indian mustard for ten quantitative traits revealed preponderance of non-additive gene effects for plant height, number of primary branches per plant and seed yield per plant, whereas additive gene effect was found to be predominant for the inheritance of rest of the characters. The parent Durgamani, RLM-198 and Varuna were the good general combiners for seed yield and oil content. Varuna and Durgamani also exhibited desirable general combining ability effect for earliness and dwarfness. Among the cross combinations, cross Kanti  Pusa Agrani exhibited superior specific combining ability effects for seed yield, oil content and other yield attributing traits. Most of the crosses involving high  low general combining parents, exhibited high sca effects for various traits.
