In order to study The Effects of drought Stress in response of wheat cultivars and wild genotype, a factorial experiment was carried out in completely randomized design in pot with three replications at 2017-2018 years. The wheat cultivars including (Bolani, behrang, shabrang, sistan) and wild (urartu, tauschii, speltoides) were as the first factor and irrigation treatment with three levels consisted of normal (80% of water holding capacity of soil), mild stress (60%) and severe stress (40%) was as the second factor. Physiological studies include: chlorophyll a and b, total chlorophyll, carotenoids, Water Use Efficiency, Leaf Relative water content and the was morphological: dry matter production (dry weight of plants), stem dry weight, stem fresh weight, Root dry weight, Root fresh weight, stem length and Rott length. Analysis of variance showed that simple effect of drought stress had a significant effect on the traits chlorophyll a and b, total, carotenoids, stem dry weight, plant dry weight of plant , leaf relative water contwnt, water use efficiency and also on stem length, stem fresh weight characteristics and Root dry weight. The result of the mean comparison showed that the tolerant cultivaers had the highest stem fresh weight, plant dry weight of plant, Leaf Relative water content and Water Use Efficiency. Comparison of cultivars and wild: cultiwars of Bolani and tauschii wild life showed more resistance
