영문 초록

In this study, ISSR markers were applied to assess genetic diversity and structure analysis of four tea (Camellia sinensis) populations at Gurye region in Korea. Out of 141 loci detected overall, 135 were identified to be polymorphic with a rate of 95.7% in the 60 individuals. The mean of Nei’s gene diversity (h) and Shannon’s information index (S.I) were 0.230 and 0.350, respectively. AMOVA indicated that 20.4% of the variation was due to the between population and the remaining 79.6% to the within population. The values of total genetic diversity (H_t), average gene diversity within population (H_s), and proportion of total genetic diversity partitioned among populations (G_ST) by Nei’s (1978) method were 0.284, 0.229, and 0.194, respectively. Interpopulation gene flow (Nm) of 2.06 (Nm〉1.0) indicates that genetic exchange occurred among the populations. The average genetic distances among the populations were 0.113 Hwaeomsa, 0.089 Piagol, 0.083 Jirisanplaza and 0.074 Choneunsa, respectively. Based on the cluster analysis of UPGMA, genetic relationship among the four populations was not coincide with the pattern of geographic distribution.
