Abstract: 【Objective】Cerasus serrulata(Lindley)Loudon, belonging to the Cerasus genus in the Rosaceae family,possesses renowned ornamental value along with rich and superior genetic characters for developing new flowering cherry cultivars. The present study aimed to reveal its genetic diversity and provide a theoretical basis for protecting and utilizing good C. serrulata resources.【Method】SSR markers were used to evaluate the genetic diversity of 224 C. serrulata indivi-duals from eight populations.【Result】A total of 113 alleles were detected from 17 pairs of SSR primes. The percentage of polymorphic loci was 92.65%. Nei's genetic diversity indexes at the species and population level were, respectively, 0.634 and 0.498. The Shannon diversity index was 0.939. Furthermore, the structure analysis showed that the eight po-pulations were from three different gene pools and the results predominantly agreed with the principal coordinate analysis.【Conclusion】SSR markers were used to effectively conduct a genetic diversity analysis of C. serrulata and revealed the high genetic diversity within and between C. serrulata populations.
