Evaluation of six commercial field corn hybrids for resistance to Ostrinia Nubilalis (Hubner)

Six commercially available field corn hybrids were evaluated for resistance to first-generation European corn borer at five Tennessee locations. Pioneer 519 and Funk G28278 were significantly more resistant than a susceptible standard, based on whorl feeding damage ratings and mean severity indexes. Under natural corn borer population pressures, the resistant hybrids showed no yield advantage over susceptible hybrids.
