This R package is for QTL and haplotype analysis of autotetraploid (and diploid) diallel populations. Phenotypes are regressed on genotype probabilities, and the regression coefficients are random effects. R package BGLR is used for the regression analysis. The PolyOrigin software is recommended to calculate the genotype probabilities for tetraploids.

A vignette is available to illustrate the workflow using a sample potato dataset, and more detailed information is available in the reference manual.
