Relative efficiency of GEBV-based selection compared with the conventional BLUP-based selection for various traits: fruit firmness (FF), soluble solids (SSC), russet, weighted cortex intensity (WCI), astringency (AST), titratable acidity (TA).

Estimates of narrow-sense heritability (h2) are also shown for each trait.*Estimated correlation was outside parameter space (>1.0), so constrained to 1.0.
