bread wheat lines to different environmental conditions and determine of the stability of their grain yield, one experiment was done with 30 bread wheat genotypes and two commercial wheats as checks using alpha lattice design with four replications in six experimental research stations in southern warm and dry climatical zones in Iran (Ahvaz, Darab, Dezful, Iranshahr, Khorramabad and Zabol) during 2013-14 and 2014-15 cropping seasons. The results confirmed that the effects of environment, genotype and interaction between them was significant at the 1% statistical level. The highest of grain yield devoted to t the lines no. 13 and 21, with 6.121 and 6.219 t/ha and the line no. 20 with 4.029 t/ha had the lowest the grain yield in this study. For studying of the genotype &times; environment effect and determine the stable genotypes, GGE Biplot method was used. Based on the polygonal figure, studied locations grouped in 4 mega-environments. Based on the results, the genotypes 31 for khorramabd, genotype 21 for Iranshahr, genotype 13 for Darab, Dezful and Ahvaz, and genotype 17 for Zabol, had specific adaptability. Dezful and Darab was the superior and Khorramabd was the poorest sites in this study respectively. In this study four promising lines including, genotypes no. 11,13,21 and 14 with wide adaptability and genotypes no. 18,19, 20 and 25 recognize with low adaptability respectively. گندم, پایداری عملکرد, روش GGE biplot, اثر متقابل ژنوتیپ × محیط Genotype × Environment, GGE biplot methods, Wheat, Yield stability 157 165 http://jcb.sanru.ac.ir/browse.php?a_code=A-10-1-292&slc_lang=fa&sid=1 Saeed Omrani سعید عمرانی 10031947532846009634 10031947532846009634 Yes Shahed University, Tehran دانشگاه شاهد تهران Amir Mohammad Naji امیر محمد ناجی 10031947532846009635 10031947532846009635 No Shahed University, Tehran دانشگاه شاهد تهران Mohsen Esmaeilzadeh Moghaddam محسن اسماعیل زاده مقدم 10031947532846009636 10031947532846009636 No Seed and Plant Improvement Institute, Agricultural Research Education and Extension Organization (AREEO), Karaj موسسه تحقیقات اصلاح و تهیه نهال و بذر
