The partial mitochondrial D-loop sequences segments of 30 samples from 2 local populations of Muscovy duck in Zhejiang Province were sequenced, and 10 variation sites and 8 haplotypes were detected. Compared with the reported sequence analysis of other 3 genera of Anatinae, the results showed that the genetic variation within Muscovy duck species was relatively low, and the genetic distance between Muscovy duck and mandarin duck（Aix）was shorter than that between Muscovy duck and duck（Anas spp. ）. The phylogenic tree showed that Muscovy duck was closer to mandarin duck in genetic relationship.
