Forecasting the accuracy of genomic prediction with different selection targets in the training and prediction set as well as truncation selection.

Abstract excerpt

KEY MESSAGE: Deterministic formulas accurately forecast the decline in predictive ability of genomic prediction with changing testers, target environments or traits and truncation selection. Genomic prediction of testcross performance (TP) was found to be a promising selection tool in hybrid breeding as long as the same tester and environments are used in the training and prediction set. In practice, however,...
