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.
