%X The microsatellite DNA technique was applied to estimate genetic structure of the four different geographical populations of Scapharca broughtonii. Using six microsatellite loci, genetic parameters of the four populations were calculated: heterozygosity, polymorphism information content (PIC), effective allele number, genetic distance and so on. The result indicated that the four populations were in good condition. FST values showed significant genetic differentiation among the four populations except that between the populations of JQ and SH. The Neighbour-joining tree topology constructed on the genetic distances among populations showed a clear division of them. The information on the genetic distances and diversity in the four geographical populations S. broughtonii in this study is useful for setting up suitable guidelines for founding and maintaining of cultured stocks, and for future genetic improvement by selective breeding.
