A set of 45 crosses were generated by crossing 10 lines viz., K9533, K9162, K9465, K8962, HUW234, NW2036, K9423, K9351, KRL210 and K906 following half diallel design of wheat under late sown condition. Ten parents, 45F1 hybrids and 45 F2 populations using Randomized Block Design with three replications were evaluated for yield and other important morpho-physiological characters at Kanpur (UP, India). General combining ability (GCA) and specific combining ability (SCA) for maturity and yield components traits were determined. The main objective of the research was the identification and proper selection of best performing wheat parental genotypes and best F1 crosses, based on GCA and SCA estimates under heat stress environment. Significant differences were observed among the wheat genotypes for all the studied traits. The estimates of σ2GCA and σ2SCA and its ratio (σ2GCA/σ2SCA) indicated that non-additive genetic expression was a pre-dominant for most of traits studied. K9533, K906, K9351 and K9423 were good general combiners for most of the traits under consideration, while F1 hybrids and F2 populations K9465 x K9351, K9162 x K906, NW2036 x K9351, K9162 x K8962 and HUW234 x KRL210 were best specific combiners observed for several important traits including grain yield plant-1 which can be subsequently utilized in future wheat breeding to develop high yielding new wheat cultivars from transgressive segregants recovered in latter generations.
