Wheat is commonly grown on arid-agricultural fields. Drought, is one of the environmental problem and water stresses, is the most significant factor through which the plant production restricts in the majority of agricultural fields of the world. In the production of wheat water stress often caused a serious issue around the world. In the 2018-2019 year we experienced two levels of water deficit stress (T1 is the normal control irrigations) and (T2 is the soaking dose in terminal drought) under controlled conditions. Six wheat cultivars i.e., BWDYT-1, BWDYT-2, BWDYT-3, MASR-18, NIA-Amber (drought sensitive) and Khirman (drought tolerant) were analyzed for numerous morphological and physiological parameters to determine the relative effect of diverse levels of drought stress. Correlation coefficients showed optimistic significant correlation with plant height (cm) and significant positive correlative association with tillers plant-1, length of spikes in (cm), weight of straw in (g), index of seed in (g), proline content in (μmol· g-1 fresh wt), osmotic potential (-Mpa), relative water content (%), content of potassium in (% g-1·fresh wt), glycine betin (μmol·g-1 fresh wt), soluble sugar (μ mol·g-1 fresh wt), chlorophyll content (mg·g-1fresh wt) at level of genotype and phenotype. These results observed by the results of variance that following cultivars are exhibited tolerant i.e., MASR-18 BWDYT-1, BWDYT-2, Khirman and NIA-Amber by accretion with level of osmotic potential and in higher level glycine-betain and the content of proline. While the total soluble sugar found moderate in the above cultivars. However, the cultivar BWDYT-1 showed better performance and increased more nitrate reeducates activity under water deficit condition.
