SNP data of 181 aus accessions

Genome-wide SNP genotypes (18,128,777 SNPs) for the 181 accessions were retrieved from SNP-Seek-International Rice Research Institute (https://snp-seek.irri.org/). SNPs with >25% missing data and minor allele frequency (MAF) <0.05 were excluded. A subset of 458,615 SNPs was retained after LD pruning (r² < 0.8 within a 2 kb window and 1 SNP step).针对181份种质资源的全基因组单核苷酸多态性（Single Nucleotide Polymorphism, SNP）基因型数据（共包含18128777个SNP位点），从国际水稻研究所的SNP-Seek数据库（https://snp-seek.irri.org/）获取。对缺失数据占比超过25%且次要等位基因频率（Minor Allele Frequency, MAF）小于0.05的SNP位点予以剔除；经连锁不平衡（Linkage Disequilibrium, LD）修剪（在2kb窗口内以1个SNP为步长，筛选连锁不平衡系数r²小于0.8的位点）后，最终保留了458615个SNP位点。
