Abstract

Based on a field observation，a Q analysis and R analysis from a cluster analysis of 28 morphological and physiological characteristics for 13 of Lycoris radiata germplasm sources from different localities in China were studied with a quantitative taxonomic study using L. radiata var. pumila，L. rosea，and L. haywardii as the outgroups. Results of the Q analysis showed 16 Operational Taxonomic Units （OTUs） classified as three groups at L1 = 14.12. Group I included L. radiata and L. radiata var. pumila. Also，in Group I，three clades were recognized among 13 germplasm specimens of L. radiata；the outer variation in characteristics of Jiangsu，Jiangning 1 （JS1） germplasm was greatest. The R analysis from the cluster analysis showed that flower part features were important for distinguishing relative species and different L. radiata germplasm sources. There were some differences in outer characteristics，growth and development habit，and galanthamine content of different L. radiata germplasm. Thus，in this study according to its leaf width，L. radiata can be classified as a narrow-leaf type，a broad-leaf type，and an intermediate type. ［Ch，2 fig. 3 tab. 13 ref.］
