摘　　要：本文应用分子系统发育学的方法,以“白蚝”和“赤蚝”的18SrDNA、ITS1和ITS2片段序列信息为分子标记,对它们的分类地位进行了探讨.综合上述3种分子标记的分析结果,初步认为“白蚝”应属于近江牡蛎,而“赤蚝”可能不属于近江牡蛎.There are still lots of problems in the systematic taxonomy of oysters in China. Among them, whether the widely bred “white oyster” and “red oyster” in Southern China are the same species of Crassostrea rivularis is to be revealed. We amplified the 18S rDNA sequences,ITS1 and ITS2 sequences of the “white oyster” and the “red oyster” respectively, and take them as molecular marks for molecular phylogenetic analysis. The preliminary results show that the “white oyster”should belong to Crassostrea rivularis, and the “red oyster” probably belongs to the other species.
