Abstract :

To evaluate the effect of terminal drought stress on yield an yield components of seven advanced barley lines along with cultivars of Nosrat and Yosef as checks, an experiment was carried out in split plot based on randomized complete block design with three replications in Islam Abad-e Gharb Research Station during 2011-2012. Terminal drought stress and non-stress treatments were assigned in main plots and genotypes were allocated in sub-plots. Traits such as grain yield, kernel thousand weight, plant height, biomass, spike per area, seed per spike and harvest index were measured. Drought stress and genotypes interaction was significant in grain yield, kernel thousand weight, plant height, biomass, spike per area, seeds per spike and harvest index. Genotypes were different statistically in all recorded traits. On the whole, in both drough stress and normal conditions, Nosrat and MBD-85-8 had the highest grain yield with 6480 and 6330 kg/ha, respectively. Meanwhile MBD-85-14 had the lowest grain yield with 4180 kg/ha. Therefore, Nosrat and MB-85-8 are recommendable to barley-growers encountering with terminal drought stress condition.
