Abstract
Development of wheat cultivars with high and stable yield for different environments is very important in breeding programs. In this study, 19 winter and facultative wheat genotypes along with a check cultivar (c.v. Shahreeyar) were studied for grain yield and its stability at Karaj, Arak, Ardebil, Hamedan, Mashhad, Jolgeh Rokh and Tabriz Agricultural Experimental Stations in 1997-2000 cropping seasons. The experimental design was RCB with four replications. Results of combined ANOVA showed that interaction of genotype x location x year was highly significant. Using different stability analysis methods such as CV, regression analysis and simultaneous selection for yield and stability showed similar results. Genotype C75-5 (OWL 85256*-3oh-*O-*Eoh) was determined as the superior for grain yield among all genotypes in almost all methods. Results of the study on harvest index (HI) indicated that the genotype C-75-15 (Bez- 2B/Cgn/Vratza) was superior for HI stability. Although, the correlation coefficient between grain yield and harvest index was positive and significant (r =0.36**) however, stabilities of these two traits among the genotypes, were not similar.
