بررسی خصوصیات زراعی و عملکرد دانه لاین های جو در شرایط مناطق سردسیر دیم

To find tolerant and high productive varieties under cold and drought stresses 54barley genotypes were evaluated in three separate advanced regional barley yield trial(ARBYT1,2 and 3 ) experiments at Gamloo agricultural research station in 2008-09. Experiments include 22, 14 and 18 genotypes respectively plus two check varieties as Sahand & Abidar, carried out in randomized complete block design with 3 replications. According to analysis of variance and mean comparisons of grain yield as final product of different physiological and biochemical processes and cold and drought tolerance index, 22 genotypes were selected for complimentary evaluations in next three years. These selected lines showed good performance in view of agronomic trials such as early growth vigor, days to heading, plant height, days to maturity.
