Objective: To compare the genetic differences between
wild ginseng and garden ginseng ( Panax ginseng ) Method:The sequences
of ITS 1 and ITS 2 of wild ginsengs were determined on LKB DNA sequencing station through Si lver Sequence TM DNA Sequencing System. The sequences were aligned with DNA SIS software. Results and conclusion: The ITS 1 and ITS 2 of Panax were 220～221 and 222～224 bases in length repectively. In Panax ginsehg, the seqences of ITS 1 were very stable, but ITS 2 were changeable. The ITS 2 sequences of No. 87 and No. 110 of the
wild ginseng collected from Fusong Heilongjiang (China) were exactly the same as those of No. U41680(Jun Wen) and No. U41682(Jun Wen) of garden ginseng collected from Heilongjiang Province (China) and Korea respectively, but different from those of No. U41681(Jun Wen) from Hubei Province (China) in three bases (447,449,450) The result implies that the cultivated ginsengs may have been introduced from two different pupolations of the wild ginseng.
