Abstract: The yield per plant, the content of volatile oil and the chemical composition of different Curcumae kwangsiensis were analyzed and compared. Referring to the standard of Chinese Pharmacopoeia （2015 edition）, the yield of Curcuma kwangsiensis was determined. The volatile oil was extracted according to the determination method, and the selected Curcuma kwangsiensis germplasm materials with high yield and content of volatile oil were analyzed by GC-MS method. SPSS 22.0 software was used to cluster the volatile oil components of Curcuma kwangsiensis, combined with the yield and content of volatile oil and other data to analyze the feasibility of screening excellent germplasm. The results showed that there were significant differences in the yield and chemical composition among 150 different Curcuma kwangsiensis germplasm. Eighteen excellent germplasm resources were selected. With the yield and color of volatile oil as variables, 18 germplasm materials were classified into 3 categories, 36 components were analyzed by GC-MS, and 2 categories were classified.

Key words: Curcuma kwangsiensis, high-quality germplasm, volatile oil content, cluster analysis
