From: Balanced selection on purebred and crossbred performance increases gain in crossbreds
Heterosis in crossbreds. The amount of heterosis obtained with each selection criterion was calculated as the difference between crossbred performance (CP) and breed average (BA) over generations. The general criterion for selection of purebred parents was \(SC_{i} = \left( {1 - w} \right) \cdot {\text{GEBV}}_{iP} + w \cdot {\text{GEBV}}_{iC}\). Training under genetic Models 2 and 3 was on purebred data. ODÂ =Â % QTL with over-dominance
