بررسی و مقایسه عملکرد لاین های جو متحمل به خشکی در شرایط زارعین استان یزد

Drought stress as the most important abiotic stress plays an important role in yield reduction of crop plant world wide . The study of physiological responses of different barley varieties to water stress could be a useful tool to understanding of the mechanisms of drought resistance. This study was conducted in Iran , Yazd ( semi- aried region) , to compare end season drought tolerance of 6 barley lines and cultivars that release from a national plan.Each lines and cultivars planted in 25 m-2 area . The experiment arranged as randomized complete block design with three replications . Results indicated that there was significant difference between lines and cultivars for grain yield. MBD-85-3 and MBD-85-6 produced the highest grain yield by 3972 and 3948 kg.ha-1 ,respectively.
