草莓品种的数量分类研究

STUDY ON NUMERICAL TAXONOMY OF THE CULTIVARS OF STRAWBERRY

从植物学角度对４６个草莓品种的３２项形态学性状进行观测描述，在此基础之上进行了主成份分析和聚类分析．主成份分析的结果表明：草莓形态的分化是多向的，因此在进行聚类分析时要尽可能选取具有分类意义的所有性状．聚类分析则是不同的聚类策略，其结果基本一致，只略有不同．

The authors dealt with the numerical taxonomy of the cultivars of strawberry from the aspect of botany morphology. In the research of the numerical taxonomy of botany morphology, 46 cultivars of strawberry were chosen and 32 characters of those cultivars were observed systematically. Based on those data, principal component analysis and cluster analysis were carried out. The results of principal component analysis indicate that morphology differentiations of strawberry cultivars are in many ways. The results of cluster analysis indicate that different cluster methods divide those cultivars into different groups. The method of study on numerical taxonomy of the cultivars of strawberry is only a kind of trial. The results can be used in selection for parents to be crossed in strawberry breeding.
