Genomic prediction model comparison of traits in spring barley breeding lines. The plot correlation (ρ(y_c, ĝ)) was estimated by calculating the correlation between the plot records corrected for the fixed effect (y_c), and genomic predicted breeding values (ĝ). The line correlation (ρ(\({\bar{{\bf{y}}}}_{{\bf{c}}}\), ĝ)) was estimated by calculating the correlation between the average of plot records corrected for the fixed effect based on the same line (\({\bar{{\bf{y}}}}_{{\bf{c}}}\)), and genomic predicted breeding values (ĝ). Maximum correlation, h, represents the square root of the narrow-sense plot genomic heritability, and is shown as green bar over the correlation.
