بررسی سازگاری و پایداری عملکرد ارقام و لاینهای امیدبخش گندم دوروم درآزمایش های یکنواخت سراسری اقلیم معتدل

Due to genotype ا 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,17 Elite genotypes were tested in Karaj ,Varamin, Gonbad- Neishabour - Esfahan and Kermanshah research stations in two years(3005-3007) , using RCBD. At each station land preparation has been conducted according to technical recommendations. Each plot consisting of 6 rows with row spacing of about 30 cm, at harvesting by omitting the beginning and the end of each plot, 6m was harvested. Seed rate was 500 seeds/m3 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 D-84-3 and D-84-1 were selected from this experiments.
