Abstract: A 6 x 6 diallel crosses of Indian Mustard (Brassica juncea (L.) Czern & Coss) was evaluated using combining ability analysis. Data were recorded from F1 generation for quantitative and qualitative traits under study. The variance due to sca was higher than that of due to gca for all the characters except oleic acid. The ratio of variance due to gca and sca was below unity for all the characters except in erucic acid and oleic acid. Based on gca effects of parents, BPR 380-1 and RSK 28 were good general combiners for seed yield. The hybrid SKM 532 x GM 3 had highest sca effects for seed yield followed by RSK 28 x RH(OE)0103 and BPR 380-1 x RSK 28. The parent RH(OE)0103 were found superior for erucic acid, oleic acid and linoleic acid Whereas, for the hybrid, RSK 28 x RH(OE)0103 were found to be superior for erucic acid and high oleic acid.
