Genetic Analysis for the Improvement of Grain Yield, Yield Contributing Traits and Quality in Rabi sorghum [Sorghum bicolor (L.) Moench]

An experiment was conducted, the hybrids and their parents were evaluated using thirty F1 hybrids of rabi sorghum (Sorghum bicolor (L.) Moench) developed by crossing three lines and ten testers in line × tester fashion. for their combining ability and also to check the superiority of hybrids (heterosis) over parents with respect to quality traits, grain yield and its components. Among thirty hybrids, two potential hybrids M-35-2A x RSV 2388 and 104A x Phule Vasudha were found to be good specific combiners with highest standard heterosis and per se performance for grain yield over checks CSH 15R. AKMS-66-2A and 104A were the good general combiner with males viz. Phule Vasudha, RSV 2388, Phule Revati and RSV 1910. The estimates of general combing ability and specific combining ability revealed the presence of both additive and non-additive genetic components for most of the traits under study.
