Abstract

Polygonatum species are a useful medical crop in Korea but basic study in the species was not well conducted. The study was carried out to analyse genetic diversity and intraspecific relationship of 47 Polygonatum species collected from Gyeongnam province. Their analysis was done through principle component analysis and average linkage cluster analysis with their twelve morphological traits. The result of principle component analysis showed the Prin 1, Prin 2 and Prin 3 represented 79% of total variation. By the 0.7 average distance of the cluster analysis and the calculated Euclidian distance, the 47 collected species were grouped into five groups. Group I included 22 collected species representing P. ordoratum var. pluriflorum, group II did 5 ones representing P. involucratum, group III was divided into two subclasses, 2 species including P. inflatum and 7 species including P. thunbergii, group IV also consisted of 2 subclasses, a species similar to P. thunbergii and P.involucratum, respectively, and finally group V included 8 species representing P.lasianthum var. coreanum. meaning that the useful germplasms can be collected from relatively small area.

경남지역 자생 둥글레속 수집종의 유연관계를 규명하여 품종육성을 위한 기초자료로 할용하고자 47개 수집종의 12개 형질을 대상으로 주성분 분석 및 average linkage cluster 방법으로 군을 분류한 결과는 다음과 같다. 1. 주성분 분석에서 줄기형태, 줄기색깔, 엽색, 포의 형태, 화색, 화형 등 12개 주요 형질의 주성분의 고유치에 기여율은 제3주성분까지 분석하여도 전체의 79%정도 설명할 수 있어서 47개 수집종의 분류가 가능함을 알 수 있었다. 2. 47개 수집종의 12개 주요형질을 대상으로 average linkage cluster 방법에 의한 분석치으 거리 0.7을 기준으로 군을 분류한 결과 5개군으로 분류되었다. I군은 둥굴레, II군은 용둥글레, III군은 산둥굴레 및 퉁둥굴레 특성의 중간형태를 각각 지닌 p28과 p29였으며, 제V군은 죽대로 분류되었다. 3. 경남일대 둥굴레의 특성조사와 수집종 분류결과 둥굴레와 죽대는 종간 변이가 거의 없었던 반면, 용둥굴레, 퉁둥굴레와 산둥굴레는 다양한 변이종이 분포하고 있는 것으로 나타났다.
