Accuracy of genomic prediction across genetic lines. 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 prediction across genetic lines when training and validation are on the same PRRSV isolate, across isolates, or using both isolates 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
