Abstract

Garlic is a perennial herb primarily distributed throughout the world. These plants are regarded as a medically and agricultural important crop in the world. The genetic relationships between cultivated and wild species were investigated at the population levels by constructing tree based on ISSR (inter-simple sequence repeats) markers. In addition, ISSR analysis was also conducted to estimate genetic diversity and population structure of these species. Three wild garlic populations in Korea were found to have more alleles per locus (mean 1.672 vs. 1.510) higher percent polymorphic locus (67.2 vs. 51.0), and higher diversity (0.250 vs. 0.198) than three cultivated populations. The cultivated and wild species in Korea are well separated from each other at phylogenetic trees. Although there is not direct evidence that A. victorialis is an ancestor of Korean A. sativum, there is a possibility that cultivated A. sativum in Korea has evolved from wild A. victorialis in Korea. Populations of A. victorialis may be useful in germ-plasm classification and evolutionary process.

마늘은 전 세계적으로 분포하는 다년생 초본이다. 마늘은 약리적, 경제적으로 중요한 작물이다. 야생종과 재배종의 유전관계를 ISSR 마커로 조사하였다. 또 ISSR 분석으로 이들 종의 유전적 다양도와 집단구조를 실시하였다. 한국의 세 야생 집단은 분리되어 있고 패치 분포를 보이지만 재배종에 비해 높은 유전적 다양성을 유지하고 있었다. ISS5R 마커로 야생종과 재배종의 계통관계는 잘 분리되었다. 비록 한국내 재배종 마늘이 산마늘에서 진화하였 다는 직접적 증거는 없지만 본 연구 결과 그런 가능성은 시사된다. 또한 야생종 산마늘 집단은 생식질 동정과 재배종 마늘의 진화과정에서 유익하게 쓰일 수 있다.
