Narrative
B55 is a selection from the single cross Oh45 x W92 that was released in 1963. The plant is large with a big ear and good pollen production. It has intermediate resistance to first brood European corn borer (Ostrinia nubilalis). Hybrids with B55 usually have above-average yield, satisfactory root and stalk strength, but slow ear drying. Maturity classification is AES700. B55 was developed in a research program and evaluated extensively in hybrid combinations. It was released in 1963 because of its potential value in seed production programs and further use in breeding programs.
