Genomic selection (GS) can be used to select purebreds for crossbred performance (CP). As dominance is the likely genetic basis of heterosis, explicitly including dominance in the GS model may be beneficial for selection of purebreds for CP, when estimating allelic effects from pure line data. The objective of this study was to investigate the benefits of GS of purebreds for CP based on purebred information. Results demonstrate that when at least one of the purebreds involved in a two way crossbreeding system was selected for CP, crossbred offspring had better performance than when selection in both breeds was for purebred performance. Under the hypothesis that crossbreds differ from purebreds due to dominance, GS can be applied to select purebreds for CP without crossbred data, by using a dominance model.
