Sedum alfredii is a Zn/Cd hyperaccumulator distributed in East Asia. A total of eight polymorphic microsatellite markers were developed. These loci were screened in 25 individuals from one heavy metal-tolerant population and one nontolerant population, respectively. The average allele number of these markers was 5.25 per locus, ranging from two to nine. Population-specific alleles were found at each locus. The observed and expected heterozygosities ranged from 0.000 to 0.640 and from 0.451 to 0.819. Significant deviation from Hardy-Weinberg equilibrium was detected at both the species and the population level. No significant linkage disequilibrium was detected at population level.
