Analysis of variance for combining ability revealed non-significant mean squares due to testers and lines for all the characters under study except significant mean squares observed for testers for plant height. This indicated less importance of general combining ability and additive gene effects in expression of out of 7 characters. The mean squares due to lines x testers interactions, indicating importance of specific combining ability and non-additive gene effects, were found to be highly significant for all the seven characters under study. Twenty-three out of sixty-nine crosses emerged with positive and significant sca effects for grain yield/plant. The five best crosses were Pusa Bas.-1 x Jaya, NDRK-50046 x Jaya, NDRK-50055 x Jaya, NDRK-50054 x CSR-10 and NDRK-50063 x CSR-10 which showed significant and positive sca effects for grain yield/plant as well as some other yield components.
