Abstract:

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 non-additive genetic variances for the control of various traits. From the evaluation of GCA variances in parents, it was observed that Pusa Mahek is a best general combiner for most of the traits, followed by TM-2. Out of the 16 characters studied, seven characters exhibited significant GCA and SCA effects. The best cross combination for 50% flowering PM-27 x DRMR-150-35, TM-2 x DRMR-150-35 for days to maturity, and PM-27 x Pusa Mahek for plant height. PM-27 x TM-2 was best cross combination showing significantly high SCA and heterosis effect for several yield attributing traits.
