All predictive abilities and accuracies are based on 100 random 10-fold cross-validations (i.e. using a training population with = 124 genotypes).

a

Trait, phenotypic trait as defined in Table 1.

b

H2, broad-sense heritability (see the Materials and Methods section).

c

rSorg (SD), average predictive ability and standard deviation across 100 random 10-fold cross-validations based on 53 174 SNVs obtained from alignments to the Sorghum bicolor genome.

d

AccuSorg (SD), average accuracy of genome-wide prediction and standard deviation across 100 random 10-fold cross-validations based on 53 174 SNVs obtained from alignments to the S. bicolor genome

e

rMisc (SD), average predictive ability and standard deviation across 100 random 10-fold cross-validations based on 121 771 SNVs obtained from alignments to an M. sinensis pseudo-reference.

f

AccuMisc (SD), average accuracy of genome-wide prediction and standard deviation across 100 random 10-fold cross-validations based on 121 771 SNVs obtained from alignments to an M. sinensis pseudo-reference.

g

Average (SD), overall average and standard deviation across traits.
