^APhenols: Total extractable phenolics compounds as mg GAE⋅g^–1 kernel; ^BTannins: Condensed tannins as mg CE⋅g^–1 kernel; ^Cg and b-tocopherol as mg of α-tocopherol⋅g^–1 kernel; ^DORAC: Antioxidant capacity as μmol Trolox⋅g^–1 kernel. Different letters in the same column indicate significant differences according to Tukey test (p ≤ 0.05). ^ESEM: standard error of mean; ^Fp-values indicate statistical probability of cultivar effect (p ≤ 0.05; n = 3) after the ANOVA test.
