Abstract
Ruditapes philippinarum and R. variegate are commercially important shellfish in Korea. In order to understand the processes and organization of genetic diversity and genetic resources for the sustainable management of fisheries resources we developed 13 primer pairs for microsatellite loci in R. philippinarum and tested their cross-amplification in R. variegate. Twelve primers amplified in both species. Nine loci were polymorphic in R. philippinarum and eight in R. variegate, each with nine to 26 alleles per locus. Unbiased expected heterozygosity levels varied from 0.73 to 0.94 in R. philippinarum. All polymorphic loci possessed species-specific alleles. No linkage disequilibrium was found. Results indicated that these microsatellite were highly polymorphic and will be useful for conservation genetics of both species.
