Figure 3
PA variable correlation based on genotypic BLUP of S × G population. The Pearson pairwise correlation coefficient (ρ) is shown and colour codes give the significance of correlation tests. Skin variables are indicated in pink and seed variables are indicated in blue. The bold black lines delimit the pairwise correlation inside a tissue for a given variable category, i.e. total content, subunit percentage and composite variables. The bold green lines delimit the pairwise correlation between tissues for a given variable category.
