Abstract: In order to identify the salt tolerance of different wheat varieties in germinating stage, six wheat varieties were used as materials, and the salt stress treatments were conducted with different concentrations of NaCl (0%(CK), 1%, 1.5%, 2.0%). The germination rate, bud length, root length and shoot fresh weight were determinated. The results showed that, under the salt stress, the germination rate, bud length, root length and shoot fresh weigh reduced with the increase of salt concentration. Under high salt stress (1.5% NaCl), ‘Ningchun 4’and‘Drasdal’were sensitive to salt in the germinating stage;‘Hongmang’wheat and ‘Maohuo’wheat had a certain salt tolerance in the germinating stage;‘Ningchun 27’and‘Shanrong 3’had strong salt tolerance. So,‘Ningchun 27’and‘Shanrong 3’had stronger salt tolerance under high salt stress.
