摘　　要：The sequences of mitochondrial cytochrome b gene of cyprinid subfamily Leuciscinae are analyzed. Phylogenetic trees generated with methods of neighbor-joining, maximum likelihood and maximum parsimony with Phenacogrammus as an outgroup indicate that Leuciscinae is not a monophyletic group but includes two discrete subgroups. The East Asian group of the subfamily Leuciscinae, including the genera Ctenopharyngodon, Elopichthys, Luciobrama, Mylopharyngodon, Ochetobius , and Squaliobarbus , is close to Aristichthys and Hypophthalmichthys , and they form a monophyletic group which is distant from the leuciscine genera in Europe, Siberia and North America, such as Phoxinus, Leuciscus, Abramis, Rutilus, Chondrostoma, Alburnus, Opsopoedus, Lythrurus , and Pimephales . Our study suggests that the diversified East Asian group of the subfamily Leuciscinae should have an independent origination.The sequences of mitochondrial cytochrome b gene of cyprinid subfamily Leuciscinae are analyzed.
