In vitro antioxidant activities (DPPH, ABTS and FRAP) of 10 cultivars of common beans from 2013 and 2014 harvest years (µmol TE/g dw). Cultivars: Arikara yellow (A1, A2, A3, A4), butter bean (B1, B2, B3), cranberry (C1, C2), red kidney (K1, K2, K3), navy (N1, N2), pinto (P1, P2, P3), black (Bk), brown eyed (BE), pink eyed (PE), and tarrestre (M).

The absence of common letters (^a–l) indicates significant differences at p < 0.05; Tukey’s multiple range tests were performed for each year separately. * indicates that it does not differ significantly at p < 0.05, between two harvesting years.
