In the first experiment of this research, in order to evaluate and compare the varieties and advanced barley lines under field conditions, as well as to observe the farmers new research findings and encourage farmers to cultivate improved barley varieties under cold dryland conditions, 28 promising barley lines with Artan, Ghafalan, Ansar, Abidar, Sahand, Arda and Barish as checks were evaluated in a randomized complete block design with 2 replications with the cooperation of farmers, promoters and experts of Hashtrud and Malekan regions in East Azerbaijan province. In the second experiment, 4 rainfed barley varieties Artan, Ghafalan, Abidar and Ansar were to be planted in large plots and under farmers' conditions in Hashtrud, Mianeh and Malekan regions with the cooperation of promoters and experts and farmers.
The Malekan experiment was lost due to the lack of care of the field by the farmers of the region. In Hashtrood the results of variance analysis and comparison of mean grain yield showed that genotypes 17 and 18 were in class D or lower than the check at the 5% probability level and the rest of the barley genotypes were in the same class as the Qaflan check (class C). In this experiment, the yield of the Artan variety and genotypes 9, 21, 24, 31, 33, 34 and 35 was higher than the Qaflan check. Lines 21 and 31 had the highest yield among the promising lines with grain yields of 2800 and 2805 kg/ha, an increase of 37 and 38 percent compared to the Qaflan variety. The highest biomass yield belonged to genotypes 9, 21, 31, 33 and 34 and the Artan and Arda varieties. Genotypes 15, 19 and 28 had the highest plant height of 65 cm and genotypes 27 and 28 had the highest 1,000-grain weight with 42 and 40 grams. The second experiment was not planted in any of these areas, despite sending the cultivars to Malekan, Mianeh, and Hashtrood.
