Increasing barley yield per unit area by using plant breeding is equal or more importance than increasing cultivated area. In this study, 20 genotypes including 17 elite barley lines with Nimroz, Auxin and WB 95-3 as checks were studied in completely randomized complete block design with 3 replications in 2018. The studied traits included number of days to heading, number of days to maturity and grain yield. Results of the ANOVA showed significant differences for grain yield, while there was no difference between genotypes for days to heading and days to maturity. Results of mean comparisons with Duncan's test at the probability level of 0.50 showed that the highest and the lowest grain yield belonged to lines 12 and 19, with 3627 kg / ha and 1442 kg / ha, respectively.
