Combining ability analysis (GCA) enables plant breeders to select parental lines for crossing and provides the opportunity to understand the nature of gene actions involved in the inheritance of desired traits. In this study, we used a line x tester mating design to generate 30 hybrid crosses using three restorer (R) and ten cytoplasmic male sterile (CMS; A) lines. Field performance of the hybrids, parents and standard checks were evaluated for grain yield and important phenological, fodder and quality traits. There were a significant effect of GCA and SCA for most of the traits evaluated, indicating the participation of additive or dominant genes in inheritance. The restorer line SPV 1822 and five male sterile lines ICSA 29003, ICSA 29004, ICSA 29011, ICSA 29014 and ICSA 29016 show potential for use as parents in sorghum breeding programs. Crosses ICSA 29004 × SPV 1822 and ICSA 29012 × SPV 1822 were identified for multilocation testing.
