TABLE 5.

Realised peach/nectarine SSC prediction accuracy for additive (A) and total (G) genomic effects, and the number of individuals in the validation population (n), for cross-trial (XT) or within-trial (WT) validation population sampling, predicted for single-trial genome-wide (STGW), multi-trial genome-wide (MTGW) or multi-trial QTL + background genome (MTQB) models by genomic environment (GEnv, for details, see Figure 2) within the trial.
