Abstract :Wheat insert ignore into journalissuearticles values(T. aestivum); has a crucial role for human diet especially in developing countries. Changes in precipitation intensity, amounts and patterns restrict wheat growth and productivity under rainfed conditions. Thus, assessment of drought effects during growth stages of wheat on grain yield and quality traits has substantial importance. Grain filling stage, coincides with early spring when the rainfall pattern highly variable, was considered in this study to evaluate effects of drought conditions on yield and quality of 16 wheat genotypes and determine superior varieties. Drought treatment inhibited plant height insert ignore into journalissuearticles values(5.5 %);, 1000 grain weight insert ignore into journalissuearticles values(9.2 %); and grain yield insert ignore into journalissuearticles values(17.7 %); while harvest index increased insert ignore into journalissuearticles values(8.5 %);. However, there was no significant effect of drought conditions on grains number spike-1 and spike numbers m-2. Protein content increased insert ignore into journalissuearticles values(31.6 %); in all genotypes, while the Zeleny sedimentation significantly decreased insert ignore into journalissuearticles values(8.2 %); with drought treatments during both growing seasons. Cultivars Pandas and Meta had higher grain yield under drought stress in both years whereas Line-28 and Pandas had better quality properties.
