随机法

The genetic variations of four ginseng populations (32 individuals) were confirmed by random amplified polymorphic DNA markers and 46.1% polymorphic sites were detected, which proved that the genetic diversity level in the garden ginseng Panax ginseng C.A.

用随机扩增多态DNA标记法对 4个人参(PanaxginsengC 。A 。Meyer)栽培群体 32个个体进行遗传多样性分析，发现RAPD多态位点为 46 。1%，证明在人参栽培群体中存在较丰富的遗传多样性。分析一路参、三路参、系选品系 5 9号、北京参等 4个人参栽培群体和 1个西洋参 P 。quinquefoliumL 。
