摘要
用数量分析的方法,对80个月季、蔷薇及其远缘杂种的样本进行了系统分析与整理。Q型聚类分析结果表明,可将80个样本分为9类,并初步揭示了各类型间的亲缘关系。首次提出了将中国古老月季分为高大和低矮两个型,将新培育出的具有较高抗性的远缘杂种月季另立为灌丛月季型的分类方案。同时,分析并预测了采用中国原产的蔷薇野生种与古老月季品种或现代月季品种杂交,后代可能形成的月季品种类型。并对花卉品种数量分类中的一些方法进行了初步探讨。
The present paper deals with the numerical classification of 80 rose species and cultivars. Roses can be classified into 9 groups through Q cluster analysis. Results obtained are conductive to the revelation of inter-relationship among these groups. It is considered that the Chinese old rose cultivars belong to two groups and some new distant-crossed roses with high resistace abilities form an independent rose group. The offspring plants by crossing Chinese wild rose species with the Chinese. old rose cultivars or modern rose cultivars represent the third type. Some problems about numerical classification of flower cultivars are discussed.
