Soil salinity limits crop productivity in many regions. This problem would be more serious as the global climate changes and worldwide water shortages would accelerate soil salinization. This study is fulfilled with aim on resolve crop cultivation in dry/saline land as an international joint research project with Tunisia. Total 48 lines of wheat cultivars including 32 common wheat (16 Korean wheat, 16 Tunisian common wheat) and 16 Tunisian durum wheat were incorporated in this study. Salt stress was applied for 2 weeks by submerging the pots into 500 mM NaCl at 3-leaf stage followed by re-watering for restoration in greenhouse. Numerous agronomic/growth parameters were scored for tolerence. SSR primers that have been known to be related to salt tolerance were applied to explain selected population. The correlation between PCR-based length polymorphism of selected lines and their resistance were evaluated. The obtained information will aid selection for salt tolerance hexa/tetraploid wheats.
