The 23 morphological characteristics from 30 accessions of 6 Lilium species and 3 varieties native to Northeast China were studied in this paper.The results showed that there were obvious differences in numerical characteristics among these wild lilies and the variation coefficient of style length and leaf width were highest with 59.49％and 54.03％ respectively.Based on the morphological data,30 wild lilies were clustered into two groups.The first group included L.lancifolium,and L.dauricum with thick stem and large flower.The second group included L.concolor var.buschianum,L.concolor var.megalanthum,L.pumilum,L.cernuum,L.leichtlinii var.maximowiczii,L.distichum and L.amabile with the smaller flower.In principal component analysis,the first four principal components represented 82.51% of the morphological differentiation.These characteristics consisted of leaf length and width,outer petal width,inner petal length and width,flora bud length,style length and anther length.
