In order to know the peanut germplasm resources in Jiangsu and explore salt tolerant resource. In this experiment, 47 peanut germplasm materials were treated with salt stress with 5 g/L NaCl, and the principal component analysis, membership function and cluster analysis were used based on the relative value of germination rate, germination energy, germination index, vigor index, fresh weight , relative water content , dry weight . The results showed that salt tolerance evaluation of peanut lines was affected with multiple indexes, relative water content and fresh weight could be used as the evaluation indexes of salt tolerance in peanut germplasm, and 5 g/L NaCl solution could be used as the suitable concentration of salt tolerance in peanut germination. 47 peanut materials were divided into 5 levels of salt tolerance, and JP42, JP29, JP23, JP43, JP35, JP4, and so on were screened out for the 6 salt tolerant germplasm. JP27 and JP98 are highly sensitive materials, and the method of membership function combined with salt tolerance can be used as a simple and rapid method for the identification of salt tolerance at germination stage.
