A set of 45 crosses of wheat were generated by crossing 10 lines viz., K-9533, K-9162, K9465, K8962, HUW-234, NW-2036, K-9423, K9351, KRL-210 and K-906 following half diallel design. Ten parents, 45F1 hybrids and 45 F2 populations using Randomized Block Design with three replications were evaluated for yield and other important morphophysiological characters at Kanpur (UP, India). Significant genetic differences were observed among the parents, F1 hybrids and F2 populations for all the characters under study. The cross K9465 x K9351 and K9162 x K906 exhibited higher heterosis over economic parent ‘K 9423’ along with considerable inbreeding depression indicating that this cross could be suitable for exploitation of hybrid vigour for grain yield. The cross, K9465 x K9351 and K9162 x K906 had stable performance in both generations hence, can be exploited for development of high yielding stable lines and or isolation of desirable segregants. Negative estimates of heterotic effects were observed in some traits may be attributed to inter-allelic interactions.
