【 摘 要 】

To compare the yield and yield components of 10 promising dryland barley genotypes with a conventional cultivar (Reihan03), a field experiment was conducted based on a randomized complete block design in Miyaneh region in the 2010-2011 growing season, and their agronomic and morphological traits were recorded. Genotypes were significantly different in terms of all the studied traits, and genotypes no. 5, 9 and 10 had higher yield than Reihan03. The studied genotypes were clustered in five groups the fifth group, consist 9.1% of genotypes, had the highest yield (1972 Kg/ha). Regression analysis showed that traits including days to ripening, length of the final internode, thousand kernel weight, plant height, and spike number per m2 accounted for 98.8% of the changes. Furthermore, there was anegative and significant (P<0.01) correlation between yield and days to ripening, chilling injury percentage and days to spike emergence, and a positive and significant (P<0.01) correlation between yield and grain filling period, spike length, seed number per spike, spike number per m2, biological yield and harvest index. Genotype no. 9 was found suitable for this region considering its superior traits such as days to ripening, grain filling period, seed number per spike, spike number per m2 and grain yield.
