title: [Analysis of genetic variation of abalone (Haliotis discus hannai) populations with microsatellite markers].
abstract: Microsatellite markers were used to access the genetic variation in three populations of abalone Haliotis discus hannai. Two wild populations were collected from the sea areas in Changdao, Shandong and Dalian, Liaoning respectively. A cultivated population originated from the sea area in Kongdongdao, Shangdong. Six microsatellite loci were screened for genetic polymorphism. Polymorphic information content (PIC) value per loci was greater than 0.5 and can be used to analysis of genetic structure of the three abalone populations. Fifty-seven alleles were amplified from the three populations in six microsatellite loci. The average number of alleles (A) was 9.50 and the effective number of alleles (Ne) was 5.8572. The mean observed heterozygosity (Ho) and the mean expected heterozygosity (He) were 0.6925 and 0.7966, respectively. The Ho and He of two wild abalone populations were higher than that of cultured population. All these results provide a basis for conservation and utilization of genetic diversity of Haliotis discus hannai.
