In bread wheat eight advance lines and four check varieties viz., GW 322, GW 366, GW 496 and LOK-1 were evaluated at three locations to estimate stability parameters for seed yield. Both linear and non-linear (pooled deviation) components of G x E variance were signifcant; however, linear component was of greater magnitude. The genotype, GW-411 had mean value (2910.22 kg/ha) higher than general mean (2817.35 kg/ha), regression coeffcient around unity and minimum deviation from regression, thereby it was identifed as stable genotype across the environments.
