Accuracy, intercept and slope of the comparison of estimated and true breeding values of 1315 candidates to selection for the model including gene content (GCMTBLUP) or not (Simple BLUP), for the method of Gengler et al. [13], and for the iterative peeling method of gene prediction
^aAll individuals are genotyped
