摘要

Scallops of the Family Pectinidae are a valuable resource in marine industry of the world.Understanding the phylogeny of the family is important for the development of the industry. In this study,partial 16S mitochondrial rDNA genes were obtained from 8 scallop species that are commonly cultured indigenous and transplanted species in China. Phylogenetic relationships of Pectinidae were analyzed based on the 8 sequences and other 5 published ones in GenBank, representing 9 genera of the family. The molecular phylogeny trees were constructed using 3 methods with software PHYLIP. The results showe that total 13 species of scallops clustered in 4 clades. Pecten maximus joins P. jacobaeus then Amusium pleuronectes in cluster, indicating close relationship of genus Amusium with Pecten in evolution. P. yessoensis is close to Chlamysfarreri and C. islandica. No enough material was available to single out genus Patinopecten as an independent monophyletic subfamily. The position ofAdamussium colbecki indicates that it is far from genus Pecten but near to genus Chlamys in evolution.
