A set of 4 diverse parental lines were crossed in diallel mating design without reciprocals to study the combining ability and heterosis for yield and yield attributes in Indian mustard [Brassica juncea (L.) Czern and Coss] during rabi 2017-18. All the F1 along with parents were evaluated in RBD with three replications. Analysis of variance for combining ability reveals significant variation was present among parents, crosses and among F1s and their parents. Combining ability analysis revealed importance of both additive and nonadditive genetic variances for the control of various traits. | Heterosis and combining ability analysis for seed yield and its attributes in Indian mustard [Brassica juncea (L.)
