Abstract<\/strong><\/p>\n

The experiment was carried out at the General Commission for Scientific Agricultural Research (GCSAR), Damascus\/Syria, in 2012, to assess the performance of 15 genotypes of wheat at germination and seedling stages, under artificially imposed of three osmotic potential levels (-0.6, -0.8, -1 MPa), using specific concentrations of poly ethylene glycol PEG6000, in addition to the control, according to splitplot design, according to plant growth stage, with three replicates. The results showed significant differences (P\u22640.01), among the genotypes. The genotypes (Hourani , Bohoth 7, Douma 1, Douma 41282, Douma 45367, Douma 4, Golan 2, h-8150) achieved the lowest reduction in relative drought tolerance index (RDTI) about (4, 2, 1, 8, 12, 9, 5, 3%) respectively. The media of osmotic potential caused a significantdecline in growing seedling, but the\u00a0 genotypes\u00a0 (Douma 1, HouraniBohoth 7, Douma 41282,Bohoth 8, Golan 2) had the highest seedling superioritywitha remarkableincreaseindry matteraccumulation(DMSI%)at the high level (-1MPa)\u00a0 about (36\u060c 30\u060c 42 \u060c 43\u060c 34\u060c 34\u060c 36\u060c 43\u060c 48%) respectively, compared with control. and classified as more tolerance for osmotic potential. A significant correlation between physiological\u00a0 indicators was determinedwhich appear the importance ofrelative drought tolerance index, duringseed germination,whichreflected onroot lengthincrementlater (r=0.608 **) and havingstrong (r=0.743 **) under stress conditions, during the early growth stages of wheat.<\/p>\n
