Genotype × environment interaction and stability parameters were determined for grain yield and its components by planting 52 bread wheat genotypes under normal (E1 and E3) and late sown condition (E2 and E4) during rabi 2019-20 and rabi 2020-21. The pooled analysis of variance for stability revealed that mean squares due to genotypes and environments were found highly significant for all the characters studied when tested against pooled deviation, revealed that significant variations exist among genotypes and environments. G x E interactions were found significant for all the traits studied when tested against pooled deviation, suggested that genotypes interacted significantly in different environments for all the traits studied. For grain yield per plant, genotypes AKAW 4901, K 1317 and UAS 375 recorded higher grain yield per plant and had non-significant regression coefficient as well as deviation from regression, thus, were considered as stable genotypes. Among these three genotypes, AKAW 4901 was also found to be stable for biological yield per plant, also showed stability under favourable condition for number of productive tillers per plant, number of spikelets per main spike, number of grains per main spike and flag leaf area. K 1317 was also found to be stable for 1000 grain weight, also showed stability under favourable environment for number of productive tillers per plant and biological yield per plant, and under unfavourable environment for grain filing period, plant height, spike length, number of spikelets per main spike and number of grains per main spike. UAS 375 was also found to be stable for biological yield per plant, also showed stability under favourable environment for days to 50 per cent heading, and under unfavourable environment for grain filing period, spike length and number of grains per main spike.
