Sixty hybrids developed from crossing four CMS lines with 15 restorers were studied alongwith parents for 13 yield and yield attributing characters. Among the male parental lines, BR-827-35-3-1.RTN-3, IR-46 appeared the best general combiner for grain yield and most of the component characters. The female line IR-58025A was found to be good general combiner for all the traits except’ plant height and L:B ratio of grain. The most promising specific combinations were IR 58025A x XBR-827-35-3-1, IR-58025A x RTN-3 and IR-68885AxRTN 711 for grain yield hill−1.
