Eight libraries were constructed, with 96 samples per library, and a total of 768 samples were subjected to genotyping. Lanes 1–8 represent eight libraries. Bases refer to the amount of sequencing data. R1 reads and R2 reads refer to the reads for the paired end sequence (PE150). Total reads represents the sum of R1 reads and R2 reads. A good barcode read is a sequence read that matches one of the barcodes used in ddGBS. R1 good barcode reads and R2 good barcode reads refer to the good barcode reads for the paired end sequence (PE150). R1 good ratio = R1 good barcode reads/R1 reads. R2 good ratio = R2 good barcode reads/R2 reads. The filter refers to the number of filtered individuals.
