Abstract:
To explore the genetic diversity of Chinese and Amarican Lycium，the genetic diversity of 17 Lycium materials were analyzed using SSR molecular marker technique in this study.The results showed that，46 alleles were amplified by 20 pairs of SSR primers and 2.3 alleles were amplified by per pairs，the ratio of polymorphism was 75.44%，the polymorphism information content ranged from 0.114 2(SSR111) to 0.829 1(SSR22)，with an average of 0.377 2.The diversity of the 17 Lycium materials showed low by these parameters.All the tested materials were clustered into one group based on the UPGMA cluster at the genetice similarity(GS) 0.600；American Lycium and Chinese Lycium were clustered respectively at 0.730；Lanshan wild gouqi and other domestic Lycium were divided respectively into two groups at 0.825；Lycium from Inner Mongolia and Ningxia were grouped roughly，but the GS was very high.It was indicated that the genetic basis of all the tested materials were narrow，and the clustering analysis results of them were consistent with the regional sources of the materials，and the varieties in the same cultivation area were clustered into one category，and the relationship between the cultivars and the region was basically the same.
