Two new CMS sources (CMS PEF and CMS I) along with the conventional PET source and 10 new restorer lines were crossed in a line x tester fashion to elucidate the information on the combining ability for seed yield and its components traits. A total of 40 crosses evaluated for 12 different quantitative traits. Among the lines CMS 234A and IMS 852A exhibited significant gca effects for most of the characters studied and were found to be the best combiners. Likewise, testers IB-104, DSR-35 and NS-15 were found to be good general combiners for most of the traits studied. The estimates of variance components revealed predominance of non-additive gene action for most of the characters studied.
