Thirty two hybrids developed from crossing four CMS lines with 8 restorers were studied among with parents for 14 yield and yield attributing characters. Among the male parental lines, JGL 18047, IET 26264 and RNR 26060 appeared the best general combiners for yield and important yield component traits. The most promising specific cross combinations were JMS 13A x RNR 26060 and CMS 64A x WGL 14 for grain yield and most of the component characters. | Studies on gene action and combining ability analysis in hybrid rice Oryza sativa L.
