对 85 个日本芋头品种 (Colocasia esculenta ) 的生化和形态特征进行了检测，以分析系统发育关系。块茎蛋白质的丙烯酰胺凝胶电泳揭示了主要品种的五种模式，分别称为 E、I、D、T 和 A。在小品种中还发现了另外三种模式。还对基于 40 个形态性状的芋头品种进行了聚类分析。与上述生化分析的结果一致，能够识别出七个类群，即 Eguimo、Dodare (Dotare)、Hasubaimo、Ishikawa-wase、Kurojiku、Akame 和 Tonoimo 类群为非簇状芋头品种，而 2 个类群为八头类和 Shogaimo 类群。 Yatsugashira 组显示出与非束状 Tonoimo 组相同的电泳模式。同样，Shogaimo 和 Dodare 组也表现出共同的电泳模式。因此，推测簇生品种是通过芽突变衍生自相应的非簇生品种。 Kurojiku 组可能是 Ishikawa-wase 组的起源，因为这两个组显示出共同的电泳模式。还讨论了 Hasubaimo 和 Dodare 群体之间的系统发育和形态学关系。
Both biochemical and morphological characters were examined in 85 Japanese cultivars of taro (Colocasia esculenta ) to analyze the phylogenic relationships. Acrylamide gel electrophoresis of the tuber proteins revealed five patterns, designated as E, I, D, T, and A, for the major cultivars. Additional three patterns were found in the minor cultivars. Cluster analysis of taro cultivars based on 40 morphological characters was also performed. The results which were in agreement with those of the above-mentioned biochemical analyses, enabled to identlfy seven groups, i.e. Eguimo, Dodare (Dotare), Hasubaimo, Ishikawa-wase, Kurojiku, Akame, and Tonoimo groups, for the non-fasciculated taro cultivars, while two, Yatsugashira and Shogaimo groups for the fasciculated ones. The Yatsugashira group showed elec-trophoretic patterns common to the non-fasciculated Tonoimo group. Similarly the Shogaimo and Dodare groups exhibited a common electrophoretic pattern. The fasciculated cultivars are, therefore, assumed to be derivecl from the corresponding non-fasciculated cultivars by bud mutation. The Kurojiku group may be at the origin of the Ishikawa-wase group, since these two groups showed a common electrophoretlc pattern. The phylogenic and morphological relationships between the Hasubaimo and Dodare groups were also discussed.
