Résumé
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 (Na), effective number of alleles (Ne), 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.
