Abstract: In order to explore the relationship characteristics among cut flower cultivars ofPaeonia lactiflora , 20 main specimens were analyzed by AFLP technique with 9 pairs of primers (PstI/MseI). The results showed that 733 bands were detected with 699 polymorphic bands and the polymorphic locus was up to 95.36%. Nei index was 1.4163- 1.5552 with average of 1.4740, Shannon index was 0.4197- 0.4929 with an average of 0.4490. The results of UPGMA cluster analysis indicated that Dice index was 0.458-0.741. All the specimens were classified into 5 groups at the similarity coefficient of 0.52. The research suggested that there were bigger genetic differences, and abundant genetic diversities among Paeonia lactiflora cultivars. This study provided the reference for the classification and genetic relationship analysis of Paeonia lactiflora.
