The procedure of target SNP-seq in genotyping 261 varieties with 163 perfect SNP. Library construction of target SNP-seq included two round of PCR. The first round of PCR was to capture the target SNP locus through multiplex PCR. The second round of PCR aimed to add a unique barcode adaptor for each DNA sample. Finally, the constructed library was sequenced on Highseq X platform.
