Abstract

Results from simulation using Best Linear Unbiased Prediction (BLUP) as the method of breeding evaluation when selecting, are presented for different heritabilities and population sizes. This method is compared with selection based on individual phenotypic values (mass selection). For heritabilities greater then 0.10, BLUP selection is inferior to phenotypic selection. The reasons for this are discussed, and it is concluded that with the given constrains, the higher selection intensity obtained with phenotypic selection, overrules the higher selection accuracy obtained with BLUP selection.
