Rhododendron purdomii (Ericaceae) is an endangered ornamental species endemic to the Qinling Mountains of China. Due to the impact of climate change and human disturbance, R. purdomii is threatened by habitat loss, and conservation of this species is urgently needed. In this study, we developed and characterized 13 novel microsatellite markers for R. purdomii based on next-generation sequencing data. For the 13 microsatellite markers in three R. purdomii populations, the number of alleles ranged from two to 12, the number of effective alleles was from 1.000 to 8.892, Shannon’s information index was from 0.000 to 2.320, and the observed and expected heterozygosity were from 0.000 to 1.000 and from 0.000 to 0.888, respectively. Private alleles were found in all three populations. Moderate differentiation between population pairs was indicated by pairwise FST values. The microsatellite markers developed in this study will provide opportunities for examining the genetic diversity and population structure of R. purdomii and contribute to the effective conservation of this species.
