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 variability, 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.
