بررسی سازگاری و پایداری عملکرد دانه لاینهای جو در آزمایش های یکنواخت سراسری مناطق سردسیر دیم

To study the stability and adaptability of grain yield of advanced barley genotypes in cold dryland area, 12 advanced genotypes were evaluated in Gamloo rainfed agricultural research station of Kordistan in 2006 to 2009 cropping seasons. The experimental design was randomized complete block design with four replications. In each year simple analysis of variance were implemented. Based on homogeneity of error variance, combined analysis was done over years. Results showed that the effect of years was significant at 1% percent probability level but the effects of genotypes and interaction between genotype and years was not significant. In despite of non significant differences among genotypes, Numbers 3, 5, 2 and 11 with 2956, 2860, 2830 and 2783 kgha-1 produced the highest grain yield respectively, Abidar(the check cultivar) produced 277 kgha-1 of grain yield.
