영문 초록

To monitor the traces of Korean wild tea (Camellia sinensis) populations, ISSR markers (4 ISSR primers) were analyzed in 38 populations (10 individuals per population) in Korea. A total of 32 ISSR amplicons were counted using 4 primers. Shannon’s index (S.I.) indicating genetic diversity ranged from 0.201 (Mt. Baekyoung) to 0.442 (Mt. Gunyu) with a mean of 0.343. Although the level of genetic diversity was relatively low compared to other woody plants, population differentiation was somewhat pronounced that a relatively high level of genetic differentiation among populations was found (13.28%). At least 9 groups originating from an independent progenitor population could be postulated on the basis of topology of UPGMA. As expected from the introduced and cultivated tree species, genetic relationships among the populations did not coincide with geographic affinity.
