In order to evaluation of morphological selection criteria for salt tolerance screening in wheat (T. aestivum L.) a factorial experiment based on completely randomized design in 3 replications were conducted under greenhouse condition. Salinity treatments involved 4 levels: S=1.3dSm-1 (control), 5, 10, 15 dSm-1 from calcium chloride and sodium chloride with 10:1 (Na: Ca ratio) and another factor was genotype involved 4 cultivars: Sistani, Neishabour (tolerant cultivars) and Tajan, Bahar (sensitive). The salt tolerant cultivars (Sistani and Neishabour) indicated higher values in measured morphological traits at salinity condition as dry weight of root and shoot, leaf area,biomass, leaf and tiller number, root area and root volume. Besides what was mentioned, they also showed the highest yield at salinity condition. The results of correlation between the mentioned traits and yield in different salinity levels and control condition indicated that the importance of tiller and leaf number and biomass in the selection of salinity-tolerant wheat genotypes.
