Variability of morphological characters and Inter Simple Sequence Repeat (ISSR) markers is studied in a mixed multispecies sympatric growth of wild roses in Lugansk province of Ukraine. Several methods of data analysis are used, such as Principal Coordinates Analysis, cluster analysis (UPGMA), and Bayesian analyses of population structure with the Structure 2.2 and NewHybrids programs. The results indicate that there are four species growing at the site, viz. R. canina, R. villosa, R. dimorpha, and R. podolica, as well as various hybrids between them. The hybrid nature of the specimens is confirmed by molecular data, however they are not intermediate between the parental species as to their morphology. The hybrids either coincide morphologically with one of the parents, or demonstrate novel combinations of diagnostic characters.
在乌克兰卢甘斯克省野生玫瑰混合多物种同域生长的情况下，研究了形态特征和简单序列重复区间（ISSR）标记的变异性。使用了几种数据分析方法，如主坐标分析、聚类分析（UPGMA）以及使用Structure 2.2和NewHybrids程序进行的群体结构贝叶斯分析。结果表明，该地点生长着四种玫瑰，即犬蔷薇、绒毛蔷薇、异形蔷薇和波多利卡蔷薇，以及它们之间的各种杂交种。分子数据证实了标本的杂交性质，但就形态而言，它们并非介于亲本物种之间。这些杂交种要么在形态上与亲本之一一致，要么表现出诊断特征的新组合。
