Abstract:

The F1 45 genotypes and F2 45 genotypes including ten - parents’ produced through diallel cross (excluding reciprocal) of winter wheat (Triticum aestivum L. Em. Thell) were analyzed for combining ability for yield and yield associated traits. Highly significant variances due to gca and sca in both the generations of present study for all the traits revealed that additive as well as non-additive genetic effects were involved in determining the traits. The results indicated significant differences among the parents for general combining ability and crosses for specific combining ability for all the characters studied. Among the parents considering simultaneously the per se performance and gca effects, good general combiners common in F2 generations were K0402 and HD2888for number of reproductive tillers; K8027 and K9351for spikelets/ spike and PBW343 and K0607 for grain yield per plant. On the basis of overall performance, parents PBW343, K9351, K9533 and K0607 were best general combiners for grain yield and other important yield contributing characters. In respect of grain yield per plant; the positive and significant values of sca were associated with four combinations with high per se performance like PBW343/K0607, K9533/NW2036, K0424/K0607and K0402/K0607; out of these in F1 K9533/NW2036, K0424/K0607, K9351/HD2888 and PBW343/K0607 were best with good specific combinations. All the three possible combinations namely, high x high, high x low and low x low were observed between the parents of high and low gca effects.
