Combining ability for yield and yield attributing traits in 24 hybrids generated by crossing four male sterile lines with six testers in line x tester fashion were studied along with their parents and checks (BIO 799 and PA 6129). The analysis revealed greater SCA variance than GCA variance for all the characters under study except for number of productive tillers per plant, hulling percentage, amylose content (%), gel consistency (mm), alkali spreading value, kernel breadth (mm), kernel length (mm) and L/B ratio which indicated the predominance of non-additive gene action in the inheritance of most of the traits and suggested for improvement through heterosis breeding. Among the parental lines, JMS 17B, CMS 14B, JGL 34990 and JMBR 44 were the best general combiners for grain yield and its contributing traits. Hence, these parents may be utilized in the development of superior hybrids. The hybrids CMS 14A X JGL 34985, JMS 18A X IRTON 270, JMS 17A X IRTON 270, CMS 14A X JGL 34990, JMS 18A X JGL 34450, JMS 13A X JGL 34450, JMS 13A X JMBR 44 and CMS 14A X JGL 35039 were the best specific combiners for grain yield and its contributing traits. Therefore, these promising hybrids based on per se performance, sca effects, gca effects of male and female parents could be recommended for heterosis breeding.
