Identity-by-state (IBS)-based genetic distance matrix between pairs of 271 accessions using 7,591 polymorphic SNPs.

Identity-by-state (IBS)-based genetic distance matrix between pairs of 271 accessions using 7,591 polymorphic SNPs.本数据集为基于同一性状态（Identity-by-state, IBS）的遗传距离矩阵，由271份种质材料两两配对的遗传距离构成，通过7591个多态性单核苷酸多态性位点（Single Nucleotide Polymorphism, SNPs）计算得到。
