An experiment was conducted to study the genetic relationships of 24 germplasms of wild lilies native to China by molecular marker technology (AFLP). Cluster analysis indicates that 24 wild lilies can be divided into 5 clusters and 4 sub-clusters, which is basically consistent with the result of morphological classification. Lilium ditichum is grouped into the first cluster, and Martagon section is remarkably distinguished from the other sections; four wild lilies of Lilium section are grouped into the second cluster; the other five wild lilies of Lilium section and L. speciosum var. gloriosoides (from Funiu Mountain) which belongs to Archelirion section or Sinomartagon section are grouped into the third cluster. The forth cluster includes L. speciosum var. gloriosoides (from Anhui) and L. duchartrei, both with fragrance in Sinomartagon section. The fifth cluster contains 11 wild lilies, most of which belong to Sinomartagon section, but the first sub-cluster has 3 species of Lophophorum section, indicating that gene exchange exists between Sinomartagon section and Lophpphorum section.
