초록

본 연구에서는 서로 다른 지역에서 재배된 장뇌삼 8품종과 밭에서 재배된 재배인삼 등 총 9개체에 대해 장뇌삼 품종들 간의 유연관계를 분석하였다. RAPD분석에 사용한 random primer는 총 40종류(OPA 1~20, OPB 1~20)였으며, 이 중 34개가 각기 다른 지역에서 재배된 품종간의 집단을 형성하여 9개 품종간 유연관계를 밝히는데 유용하였다. 유연관계를 분석한 결과, 홍천과 재배인삼, 의성과 금산, 진안과 풍기와 강화, 상주와 안동 4개의 그룹으로 구분되었으며 이는 다시 2개의 그룹 "홍천-재배인삼-의성-금산", "풍기-강화-상주-안동"으로 구분 되었다. 9개 지역에서 수집한 품종간의 유사도 값은 최저 0.30, 최고 0.53으로 나타났다. RAPD방법은 사용법이 간단하고 소요시간이 적게 소요될 뿐만 아니라 적은 양의 DNA시료로도 분석이 가능한 검정법으로 형태적인 차이가 구별되지 않는 장뇌삼 품종 간의 유전적 유연관계를 밝히는 데 유용한 방법임을 알 수 있었다. 그러나 품종별 계통유연관계를 보다 정확히 분석하기 위해서 AFLP 또는 Molecular Maker를 이용하거나 계통분류에 널리 이용되는 핵, 엽록체 DNA의 유전자 염기서열 비교와 같은 정밀한 분자계통학적 연구가 수행되어져야 할 것으로 사료된다.

This study was conducted to examine the genetic variations and intraspecific relationships between 9 individuals of Panax ginseng C.A Meyer by using RAPD (Randomly Amplified Polymorphic DNA) analysis. The 34 primers out of 40 random primers were amplified for all tested plants. The 48 (40%) among 244 bands derived from 34 primers shown polymorphism, and the 72 (64%) rest of bands showed similar forms. By regional groups Sangju and Andong samples located in Kyungsang buk-do showed a high similarity. However, Punggi located in Kyungsang buk-do showed higher similarity with Jinan's of Junla buk-do. In this way, it did not show that Panax ginseng from the same area has similarities. In future study we need to more specific molecular phylogenetic analysis such as AFLP technology and gene sequencing with nuclear chloroplast DNA in all samples.
