Abstract : Three mango cultivars were tested for age-related resistance to anthracnose caused by Colletotrichum gloeosporioides [Glomerella cingulata]. The infection was more severe on bronze than on light green leaves and old leaves, which were highly resistant. Spots on bronze leaves enlarged rapidly while those on old and light green leaves did not enlarge. In the field (Hainan, China), the highest infection percentage was observed on bronze leaves, while little or no infection was observed on old and light green leaves. Spore germination was highest on bronze leaves.
