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.
