Data for: Genetic diversity and phylogenetic relationships among citrus germplasm in the Western Caucasus

In our study, 130 different citrus accessions including 24 species or interspecific hybrids maintained and bred at the Federal Research Centre, the Subtropical Scientific Centre of the Russian Academy of Sciences (FRC SSC RAS) were genetically investigated using 13 biparental (ncSSR) and 13 uniparental (orgDNA) markers. After STRUCTURE analysis, the single accessions were allocated to eight genetic clusters and their relationships were elucidated. We identified twenty accessions as misclassified and reassigned them to the correct species. A high genetic diversity was observed on basis of the nuclear ncSSR markers, while on basis of the chloroplast orgDNA a clear cluster-specific genetic structure was detected.

本研究中，我们对联邦研究中心、俄罗斯科学院亚热带科学中心（FRC SSC RAS）所维护和培育的130个不同的柑橘品种，包括24个物种或种间杂交品种，利用13个双亲本（非编码简单重复序列，ncSSR）和13个单亲本（叶绿体组织DNA，orgDNA）标记进行了遗传研究。经过结构分析，单个品种被分配到八个遗传群中，并阐明了它们之间的关系。我们识别出二十个品种被错误分类，并将它们重新分配到正确的物种。基于核ncSSR标记，观察到高遗传多样性，而基于叶绿体orgDNA，则检测到了清晰的群特异性遗传结构。
