Due to genotype*environment interactions the performances of genotypes are not similar in different environments. To obtain stable cultivars of durum wheat under various environmental conditions and adaptable to drought, heat and other stresses of CWANA regions, 4 experiments i.e. IDON05 (240 entries ), MDYT-05TA (24 genotypes) , IDYT-05CA (24 genotypes)and dyt05 (24 genotypes ), were studied in the Ahwaz, ,Khorramabad ,Karaj and Dezful research stations. Land preparation and fertilizer has been applied according our routine technical recommendations. Each plot consisted 6 rows with row spacing of about 20 cm, to remove marginal effect at harvesting 3m² was harvested.Seed rate was considered 500 seeds/m2 which planted by experimental seeder. A mixture of Pumasuper and Granestar herbicides 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. Finally the most stable and superior lines with the best grain quality were selected for yield trial of next crop season.
