Combining ability analysis was studied in a 10 × 10 diallel set of bread wheat for days to flowering, plant height, number of tillers per plant, number of spikelets per spike, number of grains per spike and grains yield per plant. Analysis of variance (ANOVA) revealed the presence of significant variance due to general combining ability (GCA) among the parents for all the traits, and due to specific combining ability (SCA) among the crosses for all the traits.Combining ability analysis revealed the involvement of both additive and non additive gene action in the inheritance of most of the traits. On the basis of GCA, SCA effects and per se performance, parents PBW 343 for 4 traits, K 7903 for 3 traits, K 9423 for 2 traits and K9162 for 2 traits were found good general combiners and crosses PBW 343 x K 9423 for 2 traits, K 9162 x HD 2888 for 2 traits were found specific combiners.
