In the above article, accession numbers of raw reads, which were used in this study and registered in DDBJ Sequenced Read Archive, were not mentioned. Therefore, we herewith would like to publish the correct Materials and Methods section indicating DRA number of the reads.

False

Cleaning raw reads, mapping, and variant calls

The fastq files that contained the obtained raw reads were trimmed and cleaned with Trimmomatic software v. 0.39 (Bolger et al. 2014). Sequences were mapped to the reference sequences in BWA software (Li and Durbin 2009) separately using ‘Camarosa’ genome assembly v. 1.0.a1 (Edger et al. 2019b) and ‘Reikou’ genome assembly r2.3 (https://www.biorxiv.org/content/10.1101/2021.04.23.441065v1). The constructed sequence alignment map (sam) files were converted and sorted to produce binary alignment map (bam) files, then the duplicated reads generated as PCR duplication artifacts were excluded from the sorted bam files by the Markduplicates function of Picard tools (http://broadinstitute.github.io/picard). Variant calls were performed using the bam files for F_bulk and S_bulk in samtools software (https://github.com/samtools) and bcftools software (https://github.com/samtools/bcftools) to generate variant call format (vcf) files, then the generated vcf files were converted to tidy data to obtain comma-separated value (csv) files in the vcfR package for R software (Knaus and Grünwald 2017). The alternate allele frequency (Alt_AF) for each single-nucleotide polymorphism (SNP) position in F_bulk and S_bulk was calculated with the dplyr package for R software (Wickham et al. 2019), then we calculated a moving average of Alt_AF with the simpleSmoothTs command of the latticeExtra package (Sarkar and Andrews 2016) using Alt_AF values of the 1,000 front and 1,000 back SNPs. The regions where the difference in Alt_AF values between the two bulk populations was greater than the threshold value (P < 0.01) were designated as candidate genomic regions for the relevant QTL.
