بررسی عملکرد دانه و خصوصیات زراعی ارقام و لاین های جو بدون پوشینه در آزمایشات مقایسه عملکرد در مناطق گرمسیر و نیمه گرمسیر دیم

‭A preliminary yield trial was carried. out at Agric. Res. 8tn of Gonbad and Gachsaran and a replicated yield trial was carried out at Agric. Res. Stn of Gonbad, Kuhdasht and Gachsaran in 2003. There were 27 lines and varieties including checks (Sabra, ICNB93-369 and Izeh). Each line and variety was sown in six 6.66-meter long rows 20 centimeters apart. BaSed on comparison for seed yield and other suitable traits ten and three lines were chosen at Gonbad and Gachsaran, respectively for advanced trials. The replicated trials were carri~d out using 12 advanced genotypes ofhuIJ‬ص‭less barley at agric. Res. Stn of Gonbad, Kuhdasht and Gachsaran in a randomized complete block design with three replications. Each treatment consisted of six 6.65-meter long rows 20 centimeters apart. Annual and combined analysis of variance. was perfonne~ for seed yield at all stations. Location, genotypes and location by genotypes had significant effect on yield; the highest yield at aU locations was produced by genotype 11(3.344 tonlha), genotypes 9, I 1 and 6 had the highest yield at Gonbad, Gachsaran and Kuhdasht, respectively showing their specific adaptability.‬
