Rosa persica is considered a clonal plant because it is mainly propagated by clonal growth. Due to environmental degradation and habitat devastation, R. persica has been listed as a national second-class protected plant in China. However, the absence of research on wild populations of R. persica has impeded progress in formulating efficient conservation strategies. In this study, we investigated the clonal dispersal distance of R. persica to accurately determine the genetic diversity and population structure of the wild population in Xinjiang. We suggested that 20 m was the threshold distance with which to distinguish between different genets of plants. Based on this, we collated sequencing data from a total of 70 different genets of plants from 117 test samples. Eight populations of R. persica were primarily categorized into three subgroups: BL (Bole), TC (Tacheng) and CG (Changji). Of these, the CG subgroup exhibited the most genetic diversity. This research is the first to illustrates the clonal dispersal distance of R. persica, thus providing valuable reference guidelines for understanding the reproductive characteristics of clonal plants. In addition, the genetic diversity of R. persica provides a theoretical foundation for the formulation of conservation policies.
桃叶蔷薇被认为是一种克隆植物，因为它主要通过克隆生长进行繁殖。由于环境退化和栖息地破坏，桃叶蔷薇在中国已被列为国家二级保护植物。然而，对桃叶蔷薇野生种群缺乏研究阻碍了制定有效保护策略的进展。在本研究中，我们调查了桃叶蔷薇的克隆扩散距离，以准确确定新疆野生种群的遗传多样性和种群结构。我们认为20米是区分不同植株无性系的阈值距离。基于此，我们整理了来自117个测试样本中总共70个不同植株无性系的测序数据。桃叶蔷薇的8个种群主要分为三个亚组：BL（博乐）、TC（塔城）和CG（昌吉）。其中，CG亚组表现出最高的遗传多样性。本研究首次阐明了桃叶蔷薇的克隆扩散距离，从而为理解克隆植物的繁殖特性提供了有价值的参考指南。此外，桃叶蔷薇的遗传多样性为保护政策的制定提供了理论基础。
