Due to genotype x environment interactions the performance of genotypes are not similar in different environments. To obtain stable cultivars of durum wheat for harsh environments and adaptable to drought, heat and other stresses, 1 7 Elite genotypes were tested 111 Khorram Abad , Darab, Dezfol , Ahwaz and Zabol research stations in two years(2002-2004) , using ReBD. At each station land preparation has been conducted according to technical recommendations. Each plot consisting of 6 rows with row spacing of about 20 ems, at harvesting by omitting the beginning and the end of each plot, 6m2 was i harvested. Seed rate was 450 seeds/m ' which planted by experimental seeder. A mixture of Puma Super and Granestar was used for controlling of weeds. Phenological and -agronomical characteristics such as days to heading and maturity, plant height, lodging and response to diseases (Yellow rust, Common bunt and ... ) were recorded. After harvesting the yield data of genotypes was analyzed and the means were ranked and finally two most stable lines were selected from this experiments(No. 17 and18).
