Combining ability analysis for yield and yield attributes in Indian mustard [Brassica juncea (L.) Czern & Coss.]

Abstract

A set of 5×5 diallel crosses of Indian mustard along with their parents were evaluated to estimate general and specific combining ability of parents and crosses, respectively during winter season 2017-18. Significant differences were observed for both general combining ability and specific combining ability for all the thirteen traits studied. The high magnitude of general combining ability and specific combining ability effects indicated the presence of both additive and non-additive gene interactions for the inheritance of different studied traits. SCA effects, the high ranking crosses for yield and its component traits were IC-589681× IC-571649, IC-589680× IC-589681.
