Combining ability analysis for yield and its components in bread wheat (Triticum aestivum L.) under abiotic stress

Combining ability analysis for yield and its component under late sown condition in bread wheat involved ten diverse parents and their 45 F1s and their F2s indicated significance differences among the parents for gca and crosses for sca for all characters under studied. The GCA and SCA components of variances in both generations showed significant for all traits indicating additive and non additive gene action controlled the pattern of inheritance for the concern traits over the both generations. Based on the general combining ability effects and per se performance, parent K 0307 and K 0911 emerged as good general combiners for grain yield and average to high combiners for almost of the yield component characters in late sown condition, it means these genotypes probably possessed the desirable genes for heat temperature during reproductive phase. | Combining ability analysis for yield and its components in bread wheat Triticum aestivum L. under abiotic stress
