VCF of SNP genotypes for44 individuals of genus Epilobium

We used reduced representation sequencing to generate a phylogeny of <i>Epilobium</i>, which vary in their propensity to hybridise. Genetic distance was compared to the occurrence and seed set of hybrids using the literature available on this genus.A phylogeny constructed from 3522 quality-filtered SNPs from 44 samples of 10 species and four putative hybrid individuals, resolved all but one species as monophyletic. Two hybrid individuals were confirmed, and one additional hybrid was identified. All were likely to be F₁ hybrids.

我们采用简化代表测序（reduced representation sequencing）技术，构建了柳叶菜属（*Epilobium*）的系统发育树，该属植物的杂交倾向存在差异。本研究依托该属现有文献，将遗传距离与杂交种的发生情况及结实率进行了比较分析。基于10个物种的44份样本以及4个疑似杂交个体的3522个经过质量过滤的单核苷酸多态性（SNPs）构建的系统发育树，将除1个物种外的所有物种均解析为单系类群。最终确认了2个杂交个体，额外鉴定出1个杂交个体，所有这些杂交个体均极有可能为子一代（F₁）杂交种。
