Several laboratory experiments were conducted to evaluate the response of
ten ACSAD durum and bread wheat landraces to salinity stress tolerance at
seedling stage. The salinity induction response technique was applied to assess
the genetic variabi
lity, and the effect of induction nature in improving the
tolerance to lethal levels of some abiotic stresses (drought and salinity). The
applied screening tool was rapid and efficient in assessing the genetic
variability for the response of studied durum and bread wheat landraces to
salinity stress tolerance.
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 str
ess 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.
