Abstract in English
This study was carried out at the Faculty of Agriculture, Damascus
University, and ACSAD during the year 2001 – 2002 in order to assess the
genetic variability of twenty wheat genotypes for osmotic stress tolerance by
using PEG-6000 as a water stress induced tool. This trial aimed to develop
a semi-natural rapid and effective screening technique in which the optimum
induction as well as lethal levels of osmotic stress are well defined .
The results revealed that the treatments –0.4 MPa and –1.5 MPa were the
optimum induction and lethal levels of osmotic stress, respectively.
