Abstract
The phylogenetic relationships of genus Eriobotrya Lindl. (Rosaceae) was evaluated based on the nuclear ribosomal internal transcribed spacers (ITS) sequence using 22 wild species of Eriobotrya, and 4 closest genera were used as an outgroup (Mespilus germanica L., Malus sieboldii (Regel) Rehder, Photinia beauverdiana C.K Schneid. and Rhaphiolepis indica (L.) Lindl.). Our results supported the view that the Eriobotrya species were monophyletic and suggested that E. condaoensis, E. henryi and E. seguinii as the most primitive group of Eriobotrya. Our results also suggest that E. grandiflora considered as a valid species and have close relationship to E. fragrans. We reported here three more taxa of the genus for the first time, E. hookeriana have close relationship with E. petiolata; E. bengalensis f. contractahave close relationship with E. malipoensis and E. bengalensis var. intermedia have close relationship to E. salwinensis and E. tengyehensis. Furthermore, it was also resolved that E. malipoensis have close relationship to E. bengalensis var. contracta. In addition, E. cavaleriei and E. fragrans were found to be distantly related to each other
