Abstract

The present investigation was undertaken to assess the combining ability of parents and also to estimate the extent of heterosis for eleven different characters in 40 hybrids which were derived by crossing four CMS lines with ten testers in a line x tester mating design during kharif 2015. The resultant hybrids and parents along with standard checks, LSFH-35 and LSFH-171 were evaluated for seed yield and yield contributing traits. CMSPET 89-1A and CMS PET 2-7-1A, were good combiners for seed yield and oil content, respectively. Two restorers RHA138-2, EC 601957 were found to be the best general combiners for yield and other yield contributing traits. The best cross combinations, PET 2-7-1A x EC 601957,CMS 234A x EC 601924, PET 2-7-1A X R-16 and ARM 249A x R 271-1  for seed yield per plant with high significant sca effect and heterosis have been identified.
