To identify wheat (Triticum aestivum L.) lines with desire yield stability and a number 21 elite lines along with commercial cultivars Baran, Azar2 and Sardari were evaluated in randomized compelet blocks with 4 replications in Maragheh, Sararoud, Qamlo, Uromieh, Arak, Shirvan, Hamadan, Ardabil and Zanjan, research stations during three growing seasons (2015-2018). Simple and combined ANOVA carried out on collected data revealed significant differences among the evaluated genotypes. In addition, significant genotypes by environment interactions were found to affect genotypes performance in different environments. Stations including Maragheh, Sararoud and Gamlo with the average trial yield of 2848, 2473 and 2398 kg/ha respectively, yielded significantly higher compared to the other staions and found to be more suited for the genetic yield pottential trials. Lines 6 and 10 with the average grain yield of 2198 and 2105 kg/ha produced significantly higher yield compared to the checks as well as other evaluated lines. Line 23 was found highly stable with a minimum environmental interactions, but was poor in yield potential (1850 kg/ha). Line 6 with the highest average yield of 2198 kg/ha, low high additive effect in GE interaction was recognized as desirable genotypes. Furthermore, line 10 with high yiel potential (second among the examined genotypes) and high stability was found as ideal genotype. Data collected from stations rather than Sararoud and Hamadan showed closley related.
