Table 4. Prediction accuracies (acc.) using a leave-one-out (LOO) and a leave-family-out (LFO) cross-validation strategy.

LFO was based on families including more than three lines, resulting in 45 families in total. Standard deviations are the standard deviation of the correlation coefficient.

Phenotype	LOO		LFO
	Acc.	Bias	Acc.	Bias
SSW	0.68 ± 0.04	0.98 ± 0.06	0.63 ± 0.03	0.98 ± 0.05
Protein	0.40 ± 0.05	0.96 ± 0.12	0.26 ± 0.04	0.68 ± 0.10
PY	0.46 ± 0.05	1.04 ± 0.11	0.33 ± 0.04	0.87 ± 0.10
TW	0.63 ± 0.04	0.98 ± 0.07	0.56 ± 0.03	0.92 ± 0.06
Ergosterol	0.83 ± 0.03	1.02 ± 0.04	0.79 ± 0.03	1.02 ± 0.03

SSW = standardized seed weight, Protein = protein content (TS %), PY = protein yield (hkg · ha^-1), TW = test weight (kg · hl^-1), Ergosterol = ergosterol content (%)
