Genomic DNA was extracted from 100 mg of leaf tissue from 3 young seedlings for each of the 520 rapeseed accessions using the Cetyltrimethylam-monium bromide (CTAB) method. The SNP analysis was performed in the National Key Laboratory of Crop Genetic Improvement, National Subcenter of Rapeseed Improvement in Wuhan, Huazhong Agricultural University, Wuhan, China, according to the manufacture’s protocol [39 ]. The SNP data were analyzed according to the previous used protocols [18 (link)] by Illumina BeadStudio genotyping software.
