In order to estimate the combining ability of bread wheat, 45 crosses were made using a 10 × 10 diallel design excluding reciprocals. A total of 57 genotypes (10 parents, 45 crosses, and 2 checks) were evaluated in a randomized block design with three replications across three different environments (E?, E?, and E?) at separate locations during the Rabi season of 2020-21. ANOVA estimations for combining ability revealed significant mean squares for both general combining ability (GCA) and specific combining ability (SCA) for nearly all traits in all three environments, indicating the presence of both additive and non-additive genetic variance in the inheritance of most characters. Based on pooled GCA effects, five of the ten parents: Raj4037, Raj4079, HD3086, Raj4238, and WR544 were identified as good general combiners for the majority of the traits. Across all three environments, nine of the 45 crosses exhibited notable favorable SCA effects. The crosses HD3086 × WR544, Raj4238 × WR544, Raj4238 × Raj3077, HD3086 × Raj4079, and Raj4238 × Raj4079 showed significant positive SCA effects for grain yield per plant as well as other yield-contributing traits.
