Genetic Analysis of Cultured Salvelinus fontinalis in China Inferred from Microsatellites

In order to study the population genetic structure and germplasm resource status of the Salvelinus fontinalis population, 15 microsatellite markers were used to analyze its genetic diversity. The results indicated that only one locus was monomorphic in 15 loci, the other appeared polymorphism. Total 69 alleles were detected for 14 polymorphic loci in 30 individuals tested. The allele number of 14 loci ranged from 3 to 7, and the number of average effective alleles was 3.03. Expected heterozygosity ranged 0.360 to 0.719 with an average of 0.664. The average polymorphism information content was 0.578. Above data indicated that Salvelinus fontinalis present great genetic diversity and good potential for breeding in the future.
