Accuracy of genomic prediction across PRRSV isolates. Accuracy of genomic prediction for different training-validation scenarios, presented as the average correlation between genomic estimated genetic values and adjusted phenotypes divided by the square root of heritability in the validation population for that scenario. Average accuracy of genomic prediction across PRRSV isolates without (Excluding) or with (Including) the validation genetic line in training for viral load (a) and weight gain (b). Individual points represent the accuracy of prediction for one trial, with genetic lines that are represented in both PRRSV isolates having the same black shape and gray diamonds representing the trials, which were not replicated
