Phenotypic representation of the development of Phyllachora maydis 19 dai (7 days after the first stroma formed) in four corn (Zea mays L.) hybrids (H1 to H4; Table 1) (Table 5 and Fig. 4). All hybrids were susceptible to P. maydis, and the number of stromata occasionally varied among them (Table 5 and Fig. 4). Hybrid H3’ shows a senescent corn leaf as occasionally seen with stromata surrounded by green halos. Bar = 2 cm
