This experiment was conducted using a Randomized Complete Block Design with Three replications with 10 barley cultivars in Dryland Research Station of Northern Khorasan (Shirvan) in 2004-2005 growing season. Results indicated that there was significant differences among the lines in terms of the stand percentage, days to emergence, days to heading, days to maturity, plant height, number of spikes per m2, number of seeds per spike, 1000 seed-weight and grain yield.
By mean of expected mean squares, genotypic and environmental variances were calculated. The heritability of traits was estimated. In addition, correlation coefficients were calculated and path analysis was done, Days to heading, days to maturity and 1000 grain-weight had the high level of heritability. Because of the path analysis, number of seeds per spike had the direct effect on the grain yield. The direct effect of 100 grain-weight on the grain yield was considered to be reduced most probably due to indirect and negative effect of number of seeds per spike.
