Genotypic data for 10295 SNP loci on 348 apple genetic resources x elite hybrid genotypes obtained with the Illumina Infinium 20K SNP array. Names of individuals are in column "Index". The names of their parents are in columns "P1" and "P2". More information about SNP loci is given in the file "apple_20K_marker_position_data.txt". Genotypes are encoded as AA, AB, BB, AC, BC and CC. A stands for A or T, B stands for C or G, and C represents a null allele. Missing data are encoded --.本数据集包含348份苹果遗传资源及优良杂交基因型的10295个单核苷酸多态性（SNP, Single Nucleotide Polymorphism）位点基因型数据，该数据通过Illumina Infinium 20K SNP芯片完成分型获取。供试材料的名称存储于列名为"Index"的字段中，其父母本的名称分别位于"P1"与"P2"列中。有关SNP位点的更多详细信息可查阅文件"apple_20K_marker_position_data.txt"。基因型采用AA、AB、BB、AC、BC与CC六种编码方式：其中A代表A或T碱基，B代表C或G碱基，C表示无效等位基因；缺失数据以"--"进行编码。
