Background : Panax ginseng C.A. Meyer is a perennial herb belongs to the family Araliaceae. Wild-cultivated ginseng (WCG) is a specific type of ginseng in Korea which cultivated on artificial forest cultivation method. To obtain a WCG which is similar to wild ginseng (WG), this method usually performed in a mountain using seeds or seedlings of cultivated ginseng (CG) and WG. WCG is very expensive because it is difficult to cultivate. However, systematic cultivation method have not yet been developed compared to high added value. Furthermore, very high price of WCG caused the problem that Panax notoginseng or Panax quinquefolium are sold as WCG in Korean market. In this study, we analyzed the genetic diversity of WCG collected from five areas in Korea using SSR markers. Methods and Results : WCG samples were collected from five areas in Korea (Bucheon, Cheongju, Hoengseong, Judeok and Ulsan). DNA extraction was performed using CTAB method. SSR markers were collected from the published papers. After test PCR using the markers, one of the primer pair was labeled with fluorescence dye (FAM, NED, PET, or VIC) and GeneScan analysis were performed. DNA amplification was conducted using T-100 Thermal Cycler (Bio-Rad). PCR products were separated by capillary electrophoresis on the ABI 3730 DNA analyzer (Applied Biosystems). Conclusion : Eight SSR markers were collected from the published literature and used for the analysis. From the 8 tested SSR markers, 7 SSR markers showed polymorphism between varieties. GenScan analysis were performed using the selected SSR markers to analyze the phylogenetic relationship of WCG. From the results, WCG cultivated in Korea showed that they have a very diverse genetic background.
