In order to evaluate the response of wheat cultivars to drought stress, ten wheat cultivars, in the germination and seedling growth stages, were studies based on morphological traits. Germination test was done in a randomized complete block design with four replications. Treatments consisted of ten cultivars of wheat and five osmotic potential levels (0, -2.5, -5, -7.5 and -10 times, respectively). Stress levels and cultivars were respectively considered as the main and secondary factors. In this study, stress was imposed on plants at the reproductive phase. The results showed that as osmotic potential increased in the germination tests, measured traits decreased, and this reduction was maximum in the potential changes from -5 to -7.5 in most traits. These traits were not affected by moderate levels of stress. Also Varamin, Pavan and 68DH had the highest number of rootlet and rootlet length among the studied cultivars and thus it can be stated that this Fig. have a greater ability to resist the drought.
