Abstract:

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. Whereas K 0307 showed also good general combiner as their gca effect as well as per se performance for number of spikelets, number of grains per spike, grain weight per spike, spike length, 1000 grain weight while K 0911 exhibited good general combiner for protein content based on per se performance and GCA effect in both generations. On the basis on per se performance and sca effects, DBW 14 x K 0424 and K 9533 x K 0307 possessed good super combinations for grain yield and its related components whereas, K 0607 x K 0307 exhibited good cross combination for protein content based on their per se performance in both generations. The good cross combinations were the product of high x high, high x low or low x low general combiners. Hybridization scheme for wheat improvement, such as multiple crossing or bi-parental mating could be useful in further manipulation of genes for economic purposes.
