Additional file 1: of Analysis of the genetic diversity and structure across a wide range of germplasm reveals prominent gene flow in apple at the European level

List of the 2446 accessions considered in the present study with their accession code (AcceNumber), name (AcceName), the name of the providing collection (Collection), their duplicate code according to the SSR profile (FBUNQ, see text), their ploidy level (Ploidy) determined according to the occurrences of three alleles per locus (see text), their status (Analyzed) as analyzed or not-analyzed within the duplicate group (when adequate), their documented European geographic region of origin (Eur_reg_orig), their putative country of origin (Country_orig), their group assignment (Group) inferred by the Structure analysis with the highest proportion of ancestry (qImax), and their subgroup assignment (Subgroup) inferred by the nested Structure analysis with the highest proportion of ancestry (qImax nested).

本研究纳入的2446份种质材料 (accession) 列表，包含以下信息：种质编号（AcceNumber）、种质名称（AcceName）、供种种质库名称（Collection）、基于SSR（Simple Sequence Repeat）谱型确定的重复代码（FBUNQ，详见正文）、根据每一位点存在三个等位基因的情况判定的倍性水平（Ploidy，详见正文）、重复组内的分析状态（Analyzed，分为已分析与未分析，视具体情况而定）、已记录的欧洲起源地理区域（Eur_reg_orig）、推测的起源国家（Country_orig）、通过祖先比例最高的Structure群体结构分析推断得到的类群归属（Group，即qImax），以及通过嵌套式Structure群体结构分析推断得到的子类群归属（Subgroup，即嵌套分析下的qImax nested）。本数据集为XLSX格式，文件大小394 KB。
