Abstract

In order to study on adaptability and grain yield stability of eight bread wheat cultivars (Alvand, Alamout, Zarrin, Navid, Azar 2, Sabalan, Omid and Bezostiya), a RCBD experiment was conducted during three cropping seasons (2007-2010) at six locations (Sanandaj, Gorveh, Marivan, Divandarreh, Saggez and Baneh). Simple analysis of variance (ANOVA) and combined ANOVA for three years in each location and combined ANOVA for eighteen environments were implemented. Lin and Binns parameter, environmental coefficient of variations, RICK ECOVALANCE method and SHUKLA STABILITY VARIANCE, ENVIRONMENTAL VARIANCE and RANK METHOD were used for determination of stable cultivars. Combined ANOVA (three years x six locations) results showed that the genotype, year x genotype and year x location x genotype had significantly effects on grain yield. The highest grain yield belonged to Alvand (3.74 tha 1). Results of stability analysis with Lin and Binns method showed that Sabalan, Navid and Zarrin, cultivars had the lowest inside location variance and also Zarrin and Sabalan had the lowest environmental coefficient of variations, respectively. Azar 2 the lowest ENVIRONMENTAL VARIANCE among the genotypes. Results of Riclk ecovalance method showed that Zarrin and Sabalan cultivars had the lowest amount of ecovalance. Stability analysis based on Shukla method showed that Zarrin and Sabalan cultivars had the most stablest grain yield, respectively. Also stability analysis based on RANK METHOD showed that Alvand and Sabalan cultivars had the most stablest grain yield, respectively. Based on methods that used in this study, it can be concluded that Zarrin and Sabalan cultivars could be produce stable grain yield in cold areas of Kurdestan and their could be recommended for planting at these regions.
