Five pairs of cpSSR primers with excellent amplification result, clear amplification band and good repeatability were screened from 22 pairs of cpSSR primers, and the polymorphism rate was 22.73%. By using these five pairs of cpSSR primers, 16 polymorphic loci were amplified from eight experimental materials, with an average of 3.2 loci. According to the results of duster analysis, these experimental materials were divided into three categories. The clustering results were consistent with the classification results based on chloroplast gene sequences.展开更多
