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 in year 2017 and 2018. Observations were recorded on various quantitative characters. Significant differences were observed for both general combining ability and specific combining ability for almost all the traits studied. The high magnitude of general combining ability (GCA) and specific combining ability (SCA) effects indicated the presence of both additive and non-additive gene interactions for the inheritance of different traits. Parents, IC-571663 and IC-317528 were exhibited to be good general combiners for seed yield per plant, as well as based on GCA and SCA effects, the high ranking crosses for yield and its component traits were IC-571649 × IC-571663, IC-571649 × IC-317528, IC-571649 x IC-338586 and IC-599679 x IC-338586.
