FruitBreedomics apple high-density SNP genotyping dataset

This dataset contains SNP data obtained by using the Axiom®Apple480K array (Bianco et al., 2016) on 1355 apple accessions from nine mostly European institutions and 92 apple progeny individuals from two parental combinations. Among the accessions, 1341 are diploid, 12 are triploid, and two are doubled haploid. These data were mainly obtained in the frame of the EU seventh Framework Programme project FruitBreedomics: Integrated Approach for increasing breeding efficiency in fruit tree crops (http://www.fruitbreedomics.com/). Two dataset versions are available (see tab "Versions"). In Dataset 1.0, the files with root "FruitBreedomics_apple_253K_SNP" are those used for studying apple pedigrees as described in Muranty et al (2020). In Dataset 2.1, the files with root "FruitBreedomics_apple_320K_SNP" are those used for generating high density SNP data for the apple reference population, as described in Jung et al (2020 ; see Métadonnées/Metadata for this publication). The files with the suffix ".bed" are genotyping matrix in plink binary format, the files with the suffix ".bim" contain positions of loci in plink binary format and the files with the suffix ".fam" contain identifiers of the genotypes plink binary format. This format is described at http://zzz.bwh.harvard.edu/plink/data.shtml#bed.

本数据集包含通过Axiom®Apple480K基因分型阵列（Bianco等人，2016）获取的单核苷酸多态性（SNP）数据，涉及来自9家主要欧洲机构的1355份苹果种质资源，以及来自2个杂交组合的92株苹果后代个体。其中1341份为二倍体，12份为三倍体，另有2份为双单倍体。
这些数据主要依托欧盟第七框架计划项目"FruitBreedomics：提升果树作物育种效率的整合方案"（http://www.fruitbreedomics.com/）获取。本数据集提供两个版本（详见"Versions"标签页）：在版本1.0中，以"FruitBreedomics_apple_253K_SNP"为文件名前缀的文件，即为Muranty等人（2020）中描述的用于苹果谱系研究的数据集；在版本2.1中，以"FruitBreedomics_apple_320K_SNP"为文件名前缀的文件，即为Jung等人（2020）中描述的用于构建苹果参考群体高密度SNP数据的数据集，相关文献的元数据详见Métadonnées/Metadata。
后缀为".bed"的文件为PLINK二进制格式的基因分型矩阵，后缀为".bim"的文件包含PLINK二进制格式下的基因座位置信息，后缀为".fam"的文件包含PLINK二进制格式下的基因型标识符。该格式的详细说明可参见http://zzz.bwh.harvard.edu/plink/data.shtml#bed。
