摘　　要：为筛选适宜用作国内西洋参品种特异性、一致性和稳定性测试(DUS测试)的性状及分级方法,以51份西洋参种质资源为研究材料,经表型观测、统计分析等方法对34个性状进行筛选,并对筛选后的数量性状进行分级。经变异分析、正态性检验及相关性分析,共筛选出26个适宜用作DUS测试的性状,包含7个质量性状、2个假质量性状、17个数量性状,并利用主成分分析法从中挑选出6个分组性状。采用最小显著差异(LSD)分级法对筛选后的数量性状进行分级,可分为3~9级。To identify traits and classification methods suitable for DUS(Distinctness,Uniformity,and Stability)testing of Panax quinquefolius L.in China,51 Panax quinquefolius L.germplasm resources were used as research materials,34 traits were screened by phenotypic observation and statistical analysis,and the quantitative traits after screening were graded.Through variation analysis,normality test and correlation analysis,a total of 26 traits were screened for DUS test,including 7 quality traits,2 pseudo-qualitative traits and 17 quantitative traits,and 6 grouped traits were selected by principal component analysis.The quantitative traits were classified by least significant difference(LSD)classification,which could be divided into 3 to 9 grades.
