利用 EST-SSR 对茶树品种铁观音、黄棪、金牡丹及其自然杂交后代，进行初步遗传多样性和亲缘关系分析。14对EST-SSR标记共检测到等位位点62个，平均检测到4.43个，Shannon信息指数1.22，Simpson指数0.70。在相似系数0.73时，金牡丹自然杂交后代可分为4组。结果表明，第I组与铁观音亲缘关系最近，第II组与金牡丹亲缘关系最近，第II组组内遗传多样性较高；4个组间在树幅、叶片长、叶片宽等性状上达到显著性差异，每组在性状上都具有一定的群体特征。

Genetic diversity and relationship amongCamellia sinensis“Tie guanyin”,“Huangdan”, and“Jinmudan” and its natural hybrid prodenies, were researched with EST-ESSR markers. Using 14 EST-SSR primers, 62 alleles were generated and its average value was 4.43(ranged between 1 and 7). The Shannon’s information index and Simpson index were 0.485 and 0.70 respectively. According to the similarity coefficient at 0.73, the natural hybrid progenies ofJinmudan could be clustered into 4 groups. From the results, Group I was a close relative ofTie guanyin. Group II was close related toJinmudan and expressed the high genetic variation. There were significant differences in tree width, leaf length and leaf width among 4 group progenies ofJinmudan, furthermore, each group possessed a certain group characteristics.
