DArTseq SNP Dataset for Black Spruce (Picea mariana)

This dataset comprises genome-wide single-nucleotide polymorphisms (SNPs) generated via DArTseq for a comprehensive collection of black spruce samples spanning the species' range, including several red spruce (Picea rubens) individuals. Genotypes are provided in genlight format (accessible in R via the load() function) and as a standard CSV matrix. Files labeled 'RAW' contain the complete set of samples and variants, while 'FILTERED' files include only those retained after quality control. Additionally, a VCF file (denoted as 'subset') provides data for a specific subset of 236 black spruce individuals.本数据集包含通过DArTseq技术生成的全基因组单核苷酸多态性（single-nucleotide polymorphisms, SNPs）数据，采样群体覆盖黑云杉的整个自然分布范围，同时纳入了若干红云杉（Picea rubens）个体样本。基因型数据以genlight格式（可通过R语言的load()函数加载）与标准CSV矩阵格式两种形式提供。标记为'RAW'的文件包含全部样本与变异位点的完整数据集，而'FILTERED'文件仅包含经过质量控制后保留的样本与变异位点。此外，另有一个标记为'subset'的VCF文件，提供了236个黑云杉个体的特定子集数据。
