Abstract: The whole chloroplast genome sequence of Clematis fusca var. coreana from GeneBank database was analyzed, and 11 cpSSR primer pairs were designed based on that. In addition, the transferability of the 11 pairs of cpSSR primer in different species and cultivars of Clematis were studied. The results showed that 67 cpSSRs were distributed across the whole chloroplast genome, and most of them located in the area 1 088-41 445 bp and 50 135-127 217 bp, which generally consisted of a single base A/T. All of the 11 pairs of cpSSR primer could be successfully cross-amplified in different species and cultivars of Clematis, which indicated that the 11 primer pairs for cpSSR markers had good transferability in Clematis. The average number of alleles (Na) was 10.91, effective number of alleles (Ne) was 5.40, major allele frequency (MAF) was 0.31, and polymorphism information content (PIC) was 0.79. In addition, clustering result of UPGMA of 55 samples based on cpSSR data was discussed.
