Abstract

Using combining ability studies on line x tester analysis in sorghum revealed non-additive gene action for all the traits. Environments played important role in the expression of gca and sca variances. The female parents (testers) AKMS-14A and SUMS-1A and among males (lines) SU-893, S-248, SU- 906, SU-912, SU-923, SU-934, SU-941 and SU-678 were good general combiners for grain yield and its components. While considering the sca effects and per se value, 16 hybrids were best for grain yield and component characters. All these hybrids were combination of either high x low or high x high gca parents for grain yield.
