The objectives of present study was analyzing genotype by environment (GE) interaction on the grain yields of 97promising bread wheat lines (Triticum aistivum L. (along with three control varieties under salt stress and normal conditions using additive main effects and multiplicative interaction (AMMI) model .The trials were conducted at four research locations including Yazd and Mahan of Kerman (normal conditions) and Ardakan and Ekhtiarabad of Kerman (salt stress conditions). Based on results of AMMI analysis, main effect due to E and GE interaction as well as two first interaction principal components were found to be significant (P <0.99). AMMI biplots were able to distinguish specific and widely-adapted genotypes, as well as environments with high resolution. Lines 44, 50, 55, 83, 95 in compare with under studied check varieties with the lowest contribution to GE interaction and highest mean yield were introduced as the most stable genotypes, lines 26, 53, 67 and 79 were highly adapted to normal conditions of Mahan and the lines including 14, 21, 32, 36, 45, 58 and 74 were highly adapted to salt stress conditions of Kerman.
