Abstract: The AMMI model was employed to assess the phenotypic stability of twelve bread wheat varieties over six environments under three nitrogen doses for two consecutive years i.e. 2012-13 and 2013-14 in Pantnagar. For spike length, UP 2825 was overall stable performer whereas, QLD 11 and GW 445 were found to adapt in E1. For E3 two genotypes i.e. DBW 97 and HD 3112 showed adaptability. In case of trait, number of spikelets per spike, no genotype was found stable but GW 445 in E2 showed higher value for this trait and was found well adapted to this environment and QLD 33 also had higher value with adaptability to E3.
