Abstract:

In the present investigation, all together 32 hybrids were made from crosses of four cytoplasmic male sterile lines and eight diverse testers in a line x tester matting design. These hybrids were evaluated during Rabi 2014-15 at TCA, Dholi Farm. The mean sum of squares for parents and crosses, were found significant for all traits except seed filling per cent. The significance of variance due to parents Vs crosses indicated the presence of heterosis in hybrids for all characters except days to 50% flowering and harvest index. The perusal of gca effects of 12 parents (4 CMS lines and 8 testers) for 11 traits that the NDCMS-1B was a good general combiner for oil content exhibiting significant gca effects. CMS-339/89/1Bwas good general combiner for biological yield in positive direction and for plant height in negative direction exhibiting significant gca effects. CMS-SS-502B was good combiner for head diameter, 100 seed weight, volume weight, seed yield per plant and seed filling percentage exhibiting significant gca effects. Among testers LSF-71-1-9 was good combiner for harvest index, seed yield per plant, and seed filling percentage exhibiting significant gca effects. The hybrid DSFH-4 was having significant sca effect for seed yield per plant, biological yield, harvest index, and seed filling percentage.
