WebJan 6, 2024 · Although genomic best linear unbiased prediction (GBLUP) is in practice the most popular method that is often equated with genomic prediction, genomic prediction can be based on any method that can capture the association between the genotypic data and associated phenotypes (or breeding values) of a training set. WebGenomic prediction with rrBLUP 4 Jeffrey Endelman June 15, 2013 This document shows how to use several new features that have been added to the rrBLUP package since the original publication (Endelman 2011).
