摘　　要：对收集到的12份广西山药种质资源材料进行田间种植和生物学性状观察,并根据种质资源的主要生物学性状,应用聚类分析方法,可将它们分为4个或者2个类群;同时,结合形态学与生态学特征,又可将它们分成4个类群:北方山药、南方山药、野生山药、田薯型。12 Dioscorea batatas Decne germplasm resources from Guangxi Autonomous Region were collected and planted in the fields, their major biological characters were observed and measured. These resources were classified into 4 or 2 groups by clustering analysis, according to their main biological characters. At the same time, they could be classified into 4 groups including North Dioscorea batatas Decne, South Dioscorea batatas Decne, Wildness Dioscorea batatas Decne and Disoscotea alata L. based on their morphology and ecology characters.
