Resumo

Next‐Generation Sequencing Bulk Segregant Analysis (NGS‐BSA) is efficient in detecting quantitative trait loci (QTL). Despite the popularity of NGS‐BSA and the R statistical platform, no R packages are currently available for NGS‐BSA. We present QTLseqr, an R package for NGS‐BSA that identifies QTL using two statistical approaches: QTL‐seq and G’. These approaches use a simulation method and a tricube smoothed G statistic, respectively, to identify and assess statistical significance of QTL. QTLseqr can import and filter SNP data, calculate SNP distributions, relative allele frequencies, G’ values, and log 10 ( p ‐values), enabling identification and plotting of QTL. The source code is available at https://github.com/bmansfeld/QTLseqr .
