Abstract:
Combining ability analysis was studied in a 10 x 10 diallele set of bread to understand the inheritance pattern of several yield and quality traits in bread wheat. Results showed that the GCA variances were higher than SCA variances for plant height, spike length, duration of reproductive phase, gluten content and grain yield per plant in both the generations. General predictability ratio (GPR) did not reach near to unity for any of the traits in both the generations except tryptophan content in F1 generation. On the basis of overall performance, parents K8962, K9423, PBW343, GW373, HD2733 and Sonalika were best general combiners for grain yield and other important characters. Among the cross significant and desirable SCA effects in order of merit for yield and yield contributing traits were exhibited by GW373/K8962, K9107/K8027, GW373/Sonalika, K8027/K8962, K8962/Sonalika, K9107/K9423, K8020/K9423, K9107/K9351, K9107/K8962, K9107/Sonalika. These parents may be used for simultaneous improvement in grain yield and quality attributes through an intermating population involving all possible combinations among themselves.
