Abstract
In 1981 and 1982, 5 commercial hybrids were infested with 2, 3 or 4 applications of second-generation Ostrinia nubilalis egg masses or larvae (50 eggs or 50 larvae/plant at each application). In 1983, the 5 hybrids plus 5 S1 selections from population NP11BR were treated similarly, but with 5 applications of 150 egg masses or 150 larvae/plant. Significant differences were observed between genotypes for percentage of broken heads and length of cavity in peduncles and heads (measured c. 60 days after egg hatch). Resistance to plant damage following application of either eggs or larvae was exhibited by 35R, G520, GR108 and NP11BR selection 9. Damage was significantly greater from infestations with egg masses than with larvae. Cavity lengths in peduncles and heads did not differ significantly among the levels of infestation
