Two recently released sweet corn inbreds, ‘GTS1’ and ‘GTS2,’ were evaluated as inbreds and in hybrid combination for their resistance to the corn earworm, Heliothis zea (Boddie). Based on the weight of 6-day-old larvae and on damage to corn ears in the field at 15 days after silking, the level of resistance to the corn earworm was slightly altered from the original ‘471-U6’ and ‘81-1.’ A slight change in the mechanisms of resistance was shown in that GTS1 showed a slight antibiotic effect which apparently enhanced the performance of its hybrid.
