  • Prediction models were based on best linear unbiased prediction (BLUP): a mixed model based on the pedigree additive relationship matrix and phenotypes (MA), an alternative model including pedigree-based additive and dominant relationship matrices (MADped), a genomic model including the additive genomic relationship matrix (MG), and a genomic model involving breeding values and dominance deviations (MGD).

  • a The correlation between true and estimated breeding values.

  • b The coefficient of regression of true on estimated breeding values.
