Abstract:
The present investigation was carried out using 83 genotypes consisting of 12 parental lines, 35 hybrids resulting from Line × Tester mating design, their 35 F2’s and a standard check (GHB 558). Hybrids exhibited significant moderate to high heterosis over mid parent, better parent and standard check in desired direction for all the traits except standard heterosis in days to flowering. The significant economic heterosis in desirable direction was observed in high heterotic hybrids of a grain yield per plant. Out of this hybrids, two hybrids viz., ICMA 92333 × 15388 R and ICMA 05888 × 15403 R were possess significant economic heterosis for component characters like number of effective tiller per plant, ear head girth, ear head length, dry fodder yield per plant and test weight and also exhibited significant and positive inbreeding depression for those traits, which indicating that the maximum contribution of this character towards grain yield heterosis. The hybrid ICMA 91777 × 15041 R was exhibited significant inbreeding depression for all the traits except dry fodder yield per plant. None of the cross showed significant and positive high heterosis with low inbreeding depression in desirable direction in all traits except days to maturity.
