Description
Summary:We have developed a technique for incubating Gibberella zeae ear mold on ears of maize. This technique can be used in a program of screening maize genotypes for resistance to this disease. A polyethylene bag, which serves as an incubation chamber, is placed over the ear after inoculation; this is done 7–10 days after 50% of the plants of a genotype have extended silks. The bag is removed 5–6 wk after inoculation, and the ears are visually rated for ear mold symptoms at normal harvest time. Using this technique, we have been able to distinguish degrees of resistance among hybrid genotypes.
