Ginseng (Panax ginseng Meyer) is one of the most important medicinal herbs in Asia. Its pharmacological activity comes from ginsenosides, and its roots are produced commercially for traditional and Oriental medicine. Though 17 Panax species are available around the world, there was a need to develop cultivars adapted to different climatic conditions and resistant to various diseases while still producing high-quality, high-yield roots. Thus, 12 and 9 commercial P. ginseng cultivars have been registered in South Korea and China, respectively. Those varieties show superiority to local landraces. For example, Chunpoong is more highly resistant to rusty rot disease than the local Jakyungjong landrace and has a good root shape; it is highly cultivated to produce red ginseng. The Chinese cultivar Jilin Huangguo Renshen has higher ginsenoside content than its local landraces. This review provides information about P. ginseng cultivars and offers directions for future research, such as intra- and interspecific hybridization.
