Eighty four hybrids developed from crossing three CMS lines with 28 restores were studied alongwith parents for 13 yield and yield attributing characters. Among the male parental lines, PD-19, NAUR-1 and IET-18654 appeared to be best general combiner for grain yield and most of the component characters. The female line IR-58025B was found to be good general combiner for all the traits and average general combiner for plant height and harvest index whereas poor general combiner for 1000-grain weight. The most promising specific combinations were IR-58025A x NAUR-1, IR-68888A x NAUR-1 and IR-58025A x IET-18654 for grain yield plant−1.
