Abstract:

Combining ability analysis for yield and its component traits was performed with 8lines, 3 testers and the resulting 24 crosses using Line×Tester analysis. The analysis of variance indicated significant differences among parents, lines, testers, crosses, and parents vs. crosses for almost all the traits. The ratio of sca/gca variance revealed that there was preponderance of non additive gene action in the expression of all the traits. Inbred lines viz., JML-109, CML-161, JML 112 and V25 were good general combiners for yield and yield attributing characters, Tester VQL1 was high combiner for grain yield. Among the hybrids, CML-161 X CM 212, JML-109 X VQL1 and JM-112 X V341exhibited highest significant sca effects for yield and yield attributing traits.
