Fifty genotypes of bread wheat were evaluated under three simulated environments for stability parameters with respect to grain yield and its component traits. Genotype x environment interaction was significant for all the characters. Both linear and non-linear components of G x E interaction were significant for grain yield per plant, number of spikelets per spike, number of grains per main spike and 1000-grain weight. Whereas, for number of effective tillers per plant only linear component was significant. Only one genotype JAB-95-7 showed stability for all characters. Genotypes, JAB-95-16, JAB-95-23, JAB-95-27, JAB-95-31 and JAB-95-33 were also high yielders and stable for grain yield. Effective number of tillers per plant, number of spikelets per spike, number of grains per main spike, and 1000grain weight, the major components of yield varied in compensatory fashion to impart stability to the final and complex character, yield.
