摘要: Phylogenetic relationship of the genus Eriobotyra was investigated on basis nuclear ribosomal DNA Internal Transcribed Spacer (ITS) sequence. A phylogenetic tree 15 loquat accessions (species, varieties and types) generated using Photinieae serrulata L., Osteomeles anthyllidifolia Lindl., Sorbus scopulina Hedl., Malus prunifolia (Willd.) Barkh, Pyrus pyrifolia (Burm.) Nakai as outgroups, Rhaphiolepis indica (L.) an ingroup. The study exhibited that formed a monophyletic group. In consensus trees, were divided into six clusters, i.e., Cluster I: seguinii Card. E. henryi Nakai; II: cavaleriei Rehd fragrans Champ; III: malipoensis Kuan, prinoides Rehd. & Wils.var. dadunensis H. Z. Zhang japonica Lindl.; IV: E.elliptica E.bengalensis Hook.f., Hook. f. forma angustifolia Vidal; V: salwinensis Hand-Mazz VI: deflexa var. buisanensis Nakai, serrate Vidal kwangsiensis Chun. addition, it suggested could be treated variety under Champ.
