Abstract:40 wild soybean germplasms were used as materials in this experiment and they were treated with NaCl solution of different concentration(25mmol/L,75mmol/L,125mmol/L,175mmol/L) in germination stage and changes of 4 salt resistance indexes were accessed to study the salt resistance of wild soybean germplasms in different regions.The results showed that germination rate,germination potential,germination index and germination vigor index were gradually reduced with the increment of NaCl concentration.Salt could promote germination of wild soybean germplasms in low level of salt contents.The clustering analysis showed that among 40 wild soybean germplasms,K21 and K27 of Kenli area and W34,W35,W39 of Wuqing area were more tolerant to salt,but A2,A4,A5 of Anxin area and J14,J16,J17,J18,J20 of Jizhou area and K25 of Kenli area were susceptible to salt stress,salt tolerance of others materials were in the middle.
