Random sequencing of the whole genome
We sampled a total of 160 peanut accessions. DNA was extracted from blood of each individual. Paired-end libraries with insert size of 249 bp were constructed for each individual and sequenced using the HiSeq Xten platform (Illumina). The raw sequence reads were filtered by removing the index sequences and low-quality paired reads. The work was completed by Wang et al. in Shandong Peanut Research Institute.
