  • a Heritability reported by Cleveland et al. (2012).

  • b Accuracy = correlation with progeny-test-estimated breeding values.

  • c Genomic-estimated breeding values (GEBV) calculated using all phenotyped individuals.

  • d Within each trait, the top row is for individuals with a measured phenotype; the bottom row is for individuals without a phenotype.

  • e Mean and SE based on 20 random sets of 384 markers.
