The endangered Dipterocarpus dyeri is distributed in forests of southeast Vietnam, which is expected to have low genetic diversity and high genetic population structure due to habitat loss and over-exploitation. To provide valuable information for conservation measures, nine polymorphic microsatellites were used to analyze 151 adult trees from six populations, representing the natural range of D. dyeri in Vietnam. Contrary to the expectation, this species has relatively high genetic diversity within populations, low genetic differentiation among populations, and suggesting high gene flow. Results of bottleneck tests showed evidence of a bottleneck in the TaKou population. Analysis of molecular variance showed a high genetic variation within populations compared to among populations. Bayesian analysis also indicated two genetic lineages related to geographical distances. These results highlight the importance of conserving the genetic resources of D. dyeri and will provide guidelines for species conservation in Vietnam.

濒临灭绝的Dipterocarpus dyeri分布在越南东南部的森林中，由于栖息地的丧失和过度开发，预计该物种的遗传多样性较低，遗传种群结构较高。为了提供有价值的保护措施信息，使用了九种多态微卫星来分析六个种群的151棵成年树，这些树代表了D. dyeri的自然范围。在越南。与预期相反，该物种在种群内具有相对较高的遗传多样性，在种群间具有较低的遗传分化，并暗示着较高的基因流量。瓶颈测试的结果表明TaKou人口存在瓶颈。分子变异分析表明，与种群相比，种群内部具有较高的遗传变异。贝叶斯分析还表明了两个与地理距离有关的遗传谱系。这些结果突出了保存D.dyri遗传资源的重要性，并将为越南的物种保护提供指导。
