摘要： Hynobius amjiensis was considered as one of the 29 most threatened amphibian in China. To effectively conserve, manage and recover the population of this critically endangered species, 33 single nucleotide polymorphism (SNP) markers were developed using double digest restriction-site associated DNA (ddRAD) sequencing. The minor allele frequency per locus ranged from 0.0161 to 0.5000. The observed heterozygosity and expected heterozygosity varied from 0.0323 to 0.6667 (average 0.3303) and from 0.0317 to 0.5000 (average 0.2772), respectively. The inbreeding coefficient value ranged between - 0.3315 and 0.0000. No significant deviation from Hardy-Weinberg equilibrium (P > 0.05) were found in all loci. These novel SNPs will be helpful for the population genetic assessment and conservation of H. amjiensis.
