Polyphenolic compounds were assayed in the pericarp tissue (3 biological replicates of 30 fruits per pool) of the lines by HPLC-DAD. When the purified compound was not available for exact quantification, arbitrary units corresponding to peak surface were used. Measurements show means with standard error (SE). A comparison of means was carried out using a Kruskal Wallis test with correction (Dunn). Different letters indicate significant differences (5% significance level).
