金缕梅37个品种40个选择，随机扩增多态性DNA（RAPD）标记的遗传相似性进行了评估。聚类分析结果表明，共分为7个类群，其中包括3个R. x intermedia品种，H. vernalis和H. mollis和H.日本的。三个H。Xintermedia品种Arnold Promise、Westerstede和Carmine Red与其他20个品种的聚类不紧密。xintermedia。北美种H. vernalis与亚洲精选截然不同。然而，数据表明杂交亚洲金缕梅之间存在。和H.春属植物已知的半同胞家庭之间的遗传相似性提供了证据，表明品种对'阿诺德承诺'-'冬季美丽'和'胭脂红'-'Hiltingbury'本身不太可能是半同胞。
Forty selections, including 37 cultivars of Hamamelis spp., were evaluated for genetic similarities using randomly amplified polymorphic DNA (RAPD) markers. Cluster analysis identified seven groups, which included three groups of R. x intermedia cultivars, two groups of H. vernalis, and one group each of H. mollis and H. japonica. Three H. xintermedia cultivars, 'Arnold Promise', 'Westerstede', and 'Carmine Red', did not group closely with the other 20 cultivars of H. xintermedia. Selections of the North American species H. vernalis were quite distinct from the Asiatic Selections. However, data are presented that suggest hybridization exist between Asiatic Hamamelis spp. and H. vernalis. Genetic similarities between known half-sib families provides evidence that the cultivar pairs 'Arnold Promise'-'Winter Beauty' and 'Carmine Red'-'Hiltingbury' are, themselves, not likely half-sibs.
