밀원수종 팥배나무의 선발집단 간 꽃의 형태적 특성비교와 유연관계

다국어 초록 (Multilingual Abstract)

Sobus alnifolia (Siebold & Zucc.) K. Koch. which can be used as honey plant is a deciduous broadleaved tree belonging to Rosaceae family. We examined flower morphological characteristics and classification among 9 selected populations of S. alnifolia in order to provide basic data for selection breeding. The main results examined flower characteristics from 9 populations are summarized as follows; While Mt. Chukryung population was larger in flower size compared with other populations, Mt. Deogyu population was smaller among populations. Its principal components analysis (PCA) results showed that it show 64.4% accumulated explanation from three PC. The characteristics such as flower width, petal length and petal width were highly contributed for classification among populations. According to cluster analysis based on the flower morphological characteristics, the natural S. alnifolia populations were classified into three groups; the first group of Mt. Gwangyo, Anmyundo, Mt. Chukyung, the second group of Mt. Geumo, Mt. Duryun, Mt. Deogyu, the third group of Mt. Mani, Mt. Gaji, Mt. Worak.
