Abstract excerpt
KEY MESSAGE: Using the full weight matrix and deregressed pedigree-based best linear unbiased predictions in second-stage models lead to selections and genomic predictions closer to those obtained using a single-stage model. In multi-environment genomic selection, although single-stage (SS) models are generally more efficient (no loss of information), there are contexts where they are difficult to fit, making...
