Combining ability analysis for grain and fodder yield in post rainy sorghum

Abstract

Five lines and ten testers were crossed in line x tester design to produce 50 cross combinations and were evaluated along with the check for grain yield and its components for combining ability analysis. The study revealed that total eight crosses exhibited positive significant sca effects as well as positive significant standard heterosis for both grain yield per plant as well as fodder yield per plant. The cross combination AKRMS-80-1A(39) x PKV-Kranti was the best cross combination with the sca effects of 25.93** for grain yield and 29.67** for fodder yield. Also this cross exhibited standard heterosis of 19.72% for grain yield and 32.28 % for fodder yield. Thus, total nine cross combinations appeared best due to their positive significant sca effects for both grain as well as fodder yield along with positive significant standard heterosis for both these traits.
