摘　　要：目的:通过对不同种质广西莪术进行植物形态、药材性状、挥发油产量的聚类分析,为该品种的选育和分类提供参考。方法:采用原植物鉴别法测量广西莪术的植株生长期数据。药材采收后按2010年版《中国药典》的标准记录莪术药材性状的各项数据;挑选单株质量>150 g的材料进行挥发油的提取与测定。数据采用系统分析方法进行聚类,在分类中挑选植株生长良好、药材和挥发油产量高的优良品种。结果:以植株形态不同性状为指标,样本聚为4类。以药材性状与产量为指标,样本聚为4类。以莪术挥发油为指标,按挥发油产量与颜色分类,样本聚为3类。结论:综合3次分类可将原本不确定的品种进行归类确认,系统聚类法可有效对广西莪术进行品种鉴定归类,为优良品种选育和种质资源遗传多样性考察提供参考。Objective：By cluster analysis of plant morphology,medicinal properties and volatile oil production among different germplasms of Curcuma kwangsiensis to provide reference for breeding and classification of this variety.Method：Original plant identification was adopted to measure growth period data of C.kwangsiensis.After being harvested,according to 2010 edition of Chinese Pharmacopoeia,data of medicinal properties were recorded.Materials of C.kwangsiensis were adopted to extract and determine volatile oil whose weight was heavier than 150 g.Cluster analysis was employed to select fine varieties with good plant growth,high production of herb and volatile oil.Result：With plant morphology as index,samples clustered into four categories.With medicinal properties and yield as index,samples clustered into four categories.Taking volatile oil of C.kwangsiensis as an indicator,according to yield and color of volatile oil,samples could be divided into three categories.Conclusion：Integrated three classification can confirm classification for original uncertain varieties of C.kwangsiensis.System clustering method is effective for identification and classification of C.kwangsiensis,this study provides theoretical basis for germplasm genetic diversity and breeding excellent varieties of this herb.
