Schematic description of the three scenarios tested. TS: training set, VS: validation set. Each small grey circle represents one cross of the half-diallel and the large grey triangle represents the diversity panel. In scenario 1a, GP was applied within the half-diallel population with 10-fold cross-validation repeated 10 times. In scenario 1b, the three half-sib families from each parent were used separately as TS. In scenario 2, TS was the diversity panel. See details in Table S6.
