Abstract: Salinity and drought are major problems for wheat production in the world. More than 6 % of the world’s land is affected by salinity. Beside drought, salinity as well as affecting agricultural productivity in Afghanistan. Wheat (Triticum aestivum L. ) is one of the major food crops in the Afghanistan. Elucidation of the morphological mechanisms involved in salinity tolerance is important. In this study, we used National BioResource Project (NBRP) -wheat core-collection, which consisted of 165 hexaploid wheat accessions, including landraces covering the geographical distribution and modern cultivars. In order to identify salt-tolerant accessions, we screened the core-collection based on the quantitative traits, including chlorophyll content (Chl), leaf number (LN), plant height (PH), and root length (RL) and we selected the Acc_ID 6x150 to 6x38 accessions as salt-tolerant. This study aims to recognize salt tolerant wheat genetic resources, which can then be used to accelerate wheat breeding for salt tolerance.
