Abstract :
In order to yield comparison of eight cold barley promising lines including CB-85-19,CB-85-14, CB-85-9, CB-85-15 and CB-85-10 along with three barley varieties checks(Bahman, Makoui, valfager), these experiments were conducted using RCBD withthree replications in farmer field of Torbat-e-haydaria and Fariman during 2010-2011cropping season.During the stages of growth and development, the necessary records of agriculturaland morphological traits, including the dates of spike emergence, physiologicalmaturity, plant height and 1000 seeds weight, were evaluated and after harvesting,weighing and recording the seed yield of each line, variance analysis was carried out.A randomized complete block design was performed based on the grain yield. Theresults of combining analysis showed that there were significant differences (P< 0.05)between two experimental locations for grain yield and 1000 kernels weight. Inaddition, there was a significant difference for interaction of genotype × location on1000 kernels weight. The highest grain yield (6.242 t/ha) related to CB-85-10 barleygenotype which was produced from farmer’s field in Torbat-e-haydaria and Fariman.
