  1. PCA: p-coumaric acid; FA: ferulic acid; DFA 8–O–4: 8–O–4 diferulic acid; DFA 5–5: 5–5 diferulic acid; DFA 8–5: sum (DFA 8–5 l + DFA 8–5b); DFA 8–5b: 8–5 benzofuran diferulic acid; DFA 8–5 l: 8–5 linear diferulic acid; DFAT: total diferulates sum (DFA 5–5 + DFA 8–O–4 + DFA 8–5b + DFA 8–5 l); MONOTOT: total monomers (PCA + FA); FENTOT: total hydroxycinnamates (PCA + FA + DFAT)
  2. 1: * Significant genotypic correlation coefficient because it exceeded twice its standard error; NS: Non-Significant
  3. 2: * Significant phenotypic correlation coefficient because it exceeded twice its standard error; NS: Non-Significant
