재배지 및 야생지에서 국내 차나무(Camellia sinesis L. O. Kuntze)의 유전적 다양성

Genetic Diversity Analysis of the Wild and the Cultivated Tea (Camellia sinesis L. O. Kuntze) Plants in Southern Korea

In this study, ISSR markers were applied to assess the genetic diversity and structure analysis of tea (Camellia sinesis L. O. Kuntze) among the 3 cultivated populations, a wild population and single variety population (cv. Yabukita) as a control in Korea. Out of 129 loci detected overall, 120 were identified as being polymorphic with a rate of 93.02% in the 50 individuals from the populations. The polymorphic rate of the within population was over (more than) 80% in the four populations, but 16% in the single variety population. The mean of Nei's gene diversity (h) and Shannon‘s information index (S.I.) of the cultivated populations were lower than that of the wild populations. The high values for the total gene diversity, effective and Nei’s genetic diversity indicated substantial variations among the cultivated population. In addition, the insights into the relative gene diversity among and within population of Jeonggeum-ri would be useful in breeding and for the development of strategies for tea genetic population. Based on the cluster analysis of UPGMA, the genetic relationship among the all populations was coincided with the pattern of cultural environment.
