The present investigation consisted of 45 hybrids alongwith 18 parents and four checks viz., Arawali Makka-1, Mahi Kanchan, Navjot and PEHM-2 a total 67 entries was conduted during Kharif 2002 in Randomised Block Design having three replications. The data were recorded on fourteen traits to study general and specific combining ability effects. In general inbred lines L1, L3, L11 and L15 were considered good general combiner for yield and yield contributing traits as well as for quality traits. Among the testers, the tester T2 was considered good general combiner for maturity traits, plant type traits, harvest index and starch content. Majority of the hybrids exhibited significant positive values for yield and yield contributing traits as well as quality traits. Thereby, indicating that for these traits the genes with positive effects were dominent. The variance due to lines was of greater magnitude than that of testers for most of the traits. The ratio of 62sca/62gca indicated prependerance of non-additive variance for most of the traits. Parental lines L1, L3, L11 and L15 were found to be good general combiners for grain yield per plant as well as for other traits. Hybrid L12x T1 exhibited maximum significant positive sca effects for grain yield per plant. While the hybrid L2 x T1 exhibited highest estimates of significant positive sca effects for starch content. In general, there is a close association between sca effects, relative heterosis and per se performance for grain yield per plant was observed among the best hybrid identified on the basis of sca effects.
