Method for genome-wide association study: A soybean example

Abstract

Genome-wide association studies (GWAS) are a valuable approach to identify single nucleotide polymorphisms (SNPs) associated with a phenotype of interest. There are now a variety of R-packages and command line tools available to perform GWAS. Here, we provide an example downloading and filtering SNP data, followed by GWAS analysis using the R-package rMVP.
