Abstract

To determine yield stability and the effects of the interaction between the genotype and the environment, 101 wheat genotypes were assessed over 2 years (2018-2020). The experiments were performed at different diverse locations in Kashmir traversing a significant altitudinal range viz. Khudwani (34.38°N of latitude and 77.0°E of longitude) and Wadura (34.52°N of latitude and 74.52°E of longitude) following recommended agronomical practices. Analysis of the main additive effect and multiplicative interaction (AMMI) of the seed yield variance revealed a significant genotype, environmental and genotype × environment interaction effect at p
