To increase the production and productivity in wheat cultivation, new set of varieties having good combining ability are required. Because, the choice of the most suitable breeding method depends mainly on the combining ability behaviour vis-a-vis nature of gene action involved in the control of the trait of interest to the breeder. Therefore, the present research investigation was carried out with 10 parent half diallel set consisting of parents, F1’s and F2’s to estimate the general and specific combining ability variances and effect. An overall appraisal revealed that parent Raj 3777, Raj 4037, Raj 4120 and Raj 4083 were most desirable parents while among the crosses, the cross WH 1021 x Raj 3777 emerged as good specific cross combinations for grain yield and its contributing attributes as they showed significant and high gca and sca effects for most of the characters under study.
