目的 研究重楼属植物遗传多样性，并为其种质资源的快速鉴定提供有效方法。方法 采用CDDP分子标记方法对13份不同的重楼种质资源的遗传多样性进行分析，并按照CODE128条形码编码规则为重楼属植物进行编码。结果 11条引物共扩增了80个条带，其中多态性条带73个，多态性比率91.25%，等位基因数（N_a）为1.912 5，有效等位基因数（N_e）为1.589 6，Nei's遗传多样性指数（H）为0.342 3，Shannon信息指数（I）为0.507 0。UPGMA聚类分析表明，重楼属植物遗传多样性丰富。在CDDP分子标记的基础上依据CODE128条形码编码规则为重楼属植物构建了条形码分子身份证。结论 重楼属资源遗传多样性丰富，CDDP分子标记可用于重楼属种质资源的鉴定及遗传多样性分析，且构建的条形码分子身份证检测灵敏、快捷，可用于相关科研工作和工业生产中重楼属植物的鉴定。

Objective To explore genetic diversity and phylogenic relationship among different types of Paris species and provide an effective method for the rapid identification of germplasm resources. Methods CDDP marker was used to evaluate the genetic diversity and phylogenic relationship among 13 types of Paris species. And the coding of Paris genus plants was carried out based on method of CODE128 barcode. Results Our results indicated that 73 polymorphic bands were amplified by 11 primers among 80 bands, and the ratio of polymorphic band was 91.25%. The observed number of alleles (N_a), effective number of alleles (N_e), Nei's gene diversity (H), and Shannon's information index (I) was 1.912 5, 1.589 6, 0.342 3, and 0.507 0, respectively. The results of UPGMA analysis showed that there were great differences among 13 types of Paris species on genetic diversity. Based on CDDP markers, 13 barcode molecular identity cards were constructed for Paris species based on method of CODE128 barcode. Conclusion There was abundant polymorphism among Paris species, and CDDP markers were effective to analyze the genetic diversity of Paris species, and the established barcode molecular identity for Paris species was sensitive and fast, which can be used for scientific research and industrial production of Paris genus.
