Abstract

A total of 22 polymorphic simple sequence repeat (SSR) markers have been developed and characterized from AFLP sequences of Crassostrea gigas in order to protect its natural resources. Polymorphisms of these SSR markers were evaluated in a natural population of 30 individuals collected from Shandong peninsula in China. The number of alleles ranged from three to thirteen. Observed and expected heterozygosities varied from 0.50 to 0.97, and from 0.55 to 0.91, respectively. All the SSR loci conformed to Hardy–Weinberg equilibrium after Bonferroni correction. They have showed sufficient level of polymorphisms to estimate the genetic diversity, population structure and species conservation in the C. gigas.
