A 4-yr study of 100 hybrids each year was undertaken to evaluate levels of resistance to European corn borer available to the farmer in commercial hybrids. About 90% of the maize hybrids evaluated have some resistance to whorl leaf feeding and about 75% have some resistance to sheath and sheath collar feeding. In approximately two-thirds of the hybrids evaluated in Missouri, the resistance levels could be further enhanced and susceptible hybrids improved with the introduction of additional genes for resistanceCollection: AGRIS Collection
