Seventeen wolfberry germplasm resources were used as test materials,by using SCoT markers,the genetic diversity of 17 wolfberry germplasm resources was studied to provide reference for the further development and utilization of wolfberry germplasm resources.The results indicated that selected 7 reproducible and clear bands from 42 primers were amplified by PCR,a total of 32 bands were amplified,including 30 polymorphic bands,the polymorphic rate was 93.47%;the UPGMA cluster analysis showed that 17 genetic similarity coefficient of wolfberry germplasms was from 0.30 to 1.00,the average of the similarity coefficient was 0.80.When the genetic similarity coefficient was 0.72,the test materials could be divided into four categories.The genetic diversity of wolfberry germplasm could be revealed by SCoT markers.
