[A study on AFLP fingerprinting of land races of Panax ginseng L]
1Institute of Medicinal Plant, Chinese Academy of Medical Sciences, Peking Union Medical College, Beijing 100094, China.
Objective:
To obtain more information on DNA fingerprintings of five land races of Chinese ginseng, namely, Damaya (DMY), Changbo (CB), Yuanbangyuanlu (YBYL) and Huangguo (HG).
Methods:
The five land races were detected by amplified restriction fragment polymorphism (AFLP) markers with 11 combined primers (M2, M3, M16, M20, M53, M56, M57, M68, M69, M72, M84 in Mse I).
Result And Conclusion:
Only 4.6% polymorphic sites was found. It was further verified that only a little diversity existed among the land races. The polymorphic sites of CB were much more than those of the others, which suggests that there are more heterozygotes in CB populations, and it is closer to wild ginseng than the others.
