摘要: 记录42 个切花菊品种DUS(特异性、一致性和稳定性)测试中的11 个多元性状,数值编码后进行聚类分析,结合品种的来源或选育背景,分析这种方法用于评估品种间亲缘关系的有效性。结果表明:菊花品种DUS 测试的相关多元性状在品种间具有广泛的多态性,综合这些性状的信息可以对切花菊品种进行性状相似性分析,并且类间距离的远近能够较准确反映品种间亲缘关系。

Abstract: Eleven multi-variant morphological traits,often used for DUS(Distinctness,Uniformity and Stability)test,of 42 cultivars of cut chrysanthemum were recorded for cluster analysis in order to assess their genetic relationships. And also the effectiveness of this method for assessing the genetic relationship was evaluated,in comparison with the origins and breeding backgrounds of the investigated cultivars. The results indicated that there existed considerable diversities in the 42 cut chrysanthemum cultivars considering the recorded DUS testing traits. The cluster analysis based on the morphological data indicated that the genetic relationships among the investigated cultivars of cut chrysanthemum could be accurately uncovered using the average pair-wise distances between groups.

Key words: cutting chrysanthemum, DUS-test, morphological trait, genetic relationship
