Cross-validated accuracies of prediction for marker-assisted selection of a Fusarium head blight and b Septoria tritici blotch disease severity. Markers included were selected based on different levels of significance (P values) of associations. T2 test sets included hybrids sharing both parental lines, T1 test sets hybrids sharing one parental line and T0 test sets hybrids having no parental line in common with the hybrids in the related training sets. Numbers in brackets indicate the average number of significant marker–trait associations based on 100 cross-validation runs
