To explore genotype-environment interaction and identify stable genotypes in drought stress environments, an experiment was made at the research field of the Department of Genetics and Plant Breeding, Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh. Selected eleven wheat genotypes were evaluated in a randomized completely blocked design with three replications. Data were recorded on days to 50% germination, number of tillers plant-1, plant height, days to maturity, spike length, number of spikelet spike-1, number of grains spike-1, yield plant-1, thousand grain weight, and plot yield. Different stability models like AMMI model, AMMI Stability Value (ASV), Yield Stability Index (YSI), GGE Bi-plot, Eberhart and Russell’s joint regression model, and Shukla stability analysis were used to find out most desirable and stable genotypes. All stability analysis revealed that BARI GOM 23 and BARI GOM 24 were more stable and desirable genotypes as they showed best performance among the studied genotypes. These two genotypes were the most stable and desirable genotypes under drought stress conditions.
