The genotypes of 191 common wheat accessions were characterized by a high density Wheat660K array. Based on the quality preprocessing results provided by PLINK software , 8,451 and 221,878 SNPs were removed for having call rates less than 80% and minor allele frequencies less than 0.05, respectively. No accession was removed for low genotyping (MIND > 0.1). Finally, 191 common wheat accessions containing 387,537 SNPs were retained and could be used for further analyses.
