Genomic predictive ability for diameter at breast height (DBH) and wood density (WD) as a function of training population size (A) and number of markers (B) used in random cross-validations of 86 Pinus radiata genotypes from the QTL population. Error bars correspond to standard deviations across 100 random cross-validations for each set of parameters. Analyses in (A) were based on all markers (M = 9353). The training population size in (B) was N = 43 (two-fold cross-validation) and subsets of markers were selected at random
