ABSTRACT
Objective The DNA fingerprints of cultivated Pinellia ternata collected from different geographic regions were generated by using AFLP markers to find the feasibility in analyzing their genetic diversity, relationship, and germplasm identification. Methods The DNA polymorphism of 51 cultivated germplasm of P. ternata collected from 17 different habitats and four cultivars of P. pedatisecta (outgroup) were detected by AFLP molecular markers. Results The DNA fingerprints of 51 individuals of P. ternata were obviously distinguished by eight pairs of high polymorphic and efficient primer combinations screened from 64 primer combinations. The phylogenetic clustering results revealed that all the tested cultivars were fully differentiated, and individuals from the same regions were mainly clustered together. Moreover, cultivars from East-China, including Zhejiang and Jiangsu Provinces, displayed clear genetic distinction from other regions. The clustering results were strongly supported by Bootstrap test. Conclusion AFLP Markers can be potentially used in analyzing of genetic diversity, relationship, and germplasm identification of this medicinal plant, and the germplasm from regions of East-China, including Zhejiang and Jiangsu Provinces, displays the relative separate genetic characters from other regions.
