Genetic relationships were clarified by multivariate analysis using 96 morphological characteristics in the 43 taxa of genus Prunus including thirteen peach cultivars, six plums, seven apricot or mume, three sweet cherries, four ornamental cherries, and seven wild Prunus. Among 35 inflorescence characteristics, flower type, sepal hair, pedicel hair, and inflorescence organ shapes, such as petal shape and receptacle shape, were useful to characterize the Prunus. Fruit and putamen shapes were also helpful characteristics in clarifying. Leaf size, shape, and hair were useful to distinguish genetic relationships in stone fruit trees. As the result of cluster analysis, the 43 Prunus taxa were divided into nine groups at Manhattan distance of 1389.7. The classified groups could be divided into three bigger subfamilies which were the Amygdalus including the group Ⅰ and Ⅱ, the Prunophora including the group Ⅲ to Ⅴ, and the Cerasus including group Ⅳ to Ⅸ. The biggest cluster was characterized by 13 peach cultivars as the group Ⅰ. The group Ⅱ was divided into three wild peaches, P. davidiana, P. triloba, and red leafed peach. Mumes, apricots, and plums were classified into the group Ⅲ, Ⅳ, and Ⅴ, respectively. Three Korean native cherries had very distinctive tomentose characteristics in fruit and leaf. Those ‘Baesil’, ‘Yonin’, and ‘Nanking’ were belonged to the group Ⅵ. The group Ⅶ were classified with three sweet cherry cultivars. Two cherry rootstocks and four ornamental cherries were divided into the group Ⅷ and Ⅸ in each. Although multivariate analysis derived morphological characteristics was useful to distinguish genetic relationships in genus Prunus, much more data were needed for precise analysis of sub-species and cultivars.
