ABSTRACT
To study the genetic stability of Panax quinquefolium after introduced into China for 30 years, the samples of P. quinquefolium from 14 regions of China were studied. RAPD molecular marker technology was applied in this research, and POPGEN32 data analysis and NTSYS2. 10 cluster diagram were used to analyze the data. The results showed that there are abundant genetic diversity in the ginseng samples. There were 81 polymorphic bands based on the 13 random primers. The polymorphism was 83.51%, the effective number of alleles (N(e)) was 1.456 7; Nei's gene diversity index (H) was 0.274 8; Shannon's diversity index (H(o)) was 0.419 4. The clustering analyses indicated that P. quinquefolium and P. ginseng were classified into two obvious groups, especially, it was also found that the P. quinquefolium could be divided into two obvious groups based on whether the P. ginseng was cultivated in the same region or not, but it was thought that there was not genetically a qualitative difference. Thus it suggests that a good breeding field should be established in Jilin Province of China for the germplasm purification.
