Summary:In order to understand the genetic potential of three selective breeding populations of blunt snout bream(Megalobrama amblycephala),the genetic diversity were assessed in four populations [three selective breeding populations and one foundation population(F_0) of"Pujiang No.1"selected strain]of blunt snout bream on 14 polymorphic transcriptomic microsatellite loci.The parameters of genetic variabilities in three selective breeding populations are summarized as follows:the average number of alleles(A) was7.928 6 ~ 8.785 7; the average number of effective alleles(AE) was 4.409 4 ~ 4.878 4; the value of average observed heterozygosity(HO) was 0.491 1 ~ 0.574 4; the value of average expected heterozygosity(HE) was 0.741 3 ~ 0.751 8; the value of average polymorphism information content(PIC) was 0.691 2 ~ 0.705 2; the value of average Wright's inbreeding coefficient(FIS) was 0.229 ~0.352.The genetic diversity indices of AEand HEin three selective breeding populations were higher than those in foundation population
