Screening and Grading of DUS Test Traits in Panax quinquefolius L.
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 re-sources were used as research materials,34 traits were screened by phenotypic observation and statis-tical analysis,and the quantitative traits after screening were graded.Through variation analysis,nor-mality test and correlation analysis,a total of 26 traits were screened for DUS test,including 7 quali-ty 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.
