Ten wheat genotypes tested for drought tolerance atgermination stage. Polyethylene Glycol-8000 used to induce -1.7 and -3.5 bars osmoticpotential as compared to control treatment with three replications in factorialexperiment with Completely Randomized Design (CRD). Thestudied parameters showed a decreasing in style of response to increment of PEGconcentration. The lowest Final Germination Percentage (FGP) mean recorded was73.23 % under -3.5 bars as compared to control. Means of Daily Germination time(MDG), Germination Index (GI) and Coefficient of Velocity Germination (CVG) havebeen decreased from 4.04, 3.23 and 81.64 at control treatment to 2.46, 1.77 and 69.21 atsevere drought level. But the highest CVG; 83.34 recorded by Azady under 160 g/ LPEG. In addition under -3.5 bar treatment lowest means of shoot and root lengthrecorded; 3.34 and 1.92 cm as compared to control treatment. While, lowest shootweight and whole seedling weight; 0.07 and 0.079 g recorded by Abu-ghreb, but lowestroot dry weight 0.008 g was recorded by Adena. While, a significant increase observedin proline content in all genotypes at 160 g PEG-8000/ L medium. Ezz, Sham-6, Azady,Rabeaa and Riagary seedlings’ accumulated more proline as compared to Tammuz-2,Adena, Abu-ghreb, Abehade and Ebba-99. According to the studied parameters adendrogram constructed. The genotypes classified into two groups. Resistant; includeEzz, Sham-6, Azady, Rabeaa and Rizgary. Sensitive; includes Tammuz-2, Adena, Abughreb,Abehade and Ebba-99.
