Phylogenetic Relationship Analysis of Adenophora triphylla var. japonica HARA Local Collections using RAPD Markers

Adenophora triphylla var. japonica HARA is a herbaceous plant belongs to Campanulaceae. Adenophora root is mainly used for medicinal purpose. It is effective for lung cleaning, sputum remove, viscera strengthening, cough stopping and cancer treatments. Adenophora has about 70 species in the world and 17 of the species are distributed in Korea. Genetic resources of A. triphylla var. japonica HARA are valuable as the habitat is concentrated in East Asia. The intraspecies variation is very high according to the environmental conditions. A new A. triphylla var. japonica HARA variety, ‘Harang’, was developed through polyploid breeding in 2011. But, low domestic production and passive studies caused our country to rely on imports for almost all amount of the A. triphylla var. japonica HARA demands. In this experiment, genetic diversity between the collections were analyzed using 32 RAPD primers. Through this study, limit of morphologic classification could be solved and genetic diversity of this plant could be assured.
