Objectives: To evaluate yield, uniformity, plant characteristics, and ear characteristics in the field, and processed quality of new varietal introductions of supersweet (sh2) corn.

Objectives:

• Test Plant Introduction lines and other germplasm sources for high field resistance to head smut.
• Determine if immunity or true seedling resistance exists in germplasm sources.
• Test commercial F1 hybrids and inbreds for head smut resistance.

Objectives:

• To determine the effects of planting dates and plant populations on yield and ear characteristics (especially length and tip-fill) of Jubilee sweet corn at the OSU Vegetable Research Farm.
• To determine the relationship between plant populations and yield and ear characteristics in commercial plantings of sweet corn in grower fields.

OBJECTIVES:

• Monitor corn earworm moths using pheromone and black light traps.
• Conduct a statewide pheromone trapping program.
• Conduct a comparison of pheromone traps.
• Study earworm infestation trends
• Study corn earworm overwintering success and spring emergence.
• Produce a sweet corn growth model.
• Conduct an insecticide trial.

Objectives:

Project Leaders: J. R. Baggett, Horticulture
G. W. Varseveld, Food Science and Technology

Objectives:

The project evaluates new supersweet and sugary-enhanced sweet corn varieties to identify superior plant materials. Varieties are evaluated for

• Reliability in plant stand establishment.
• Uniformity of maturity date.
• Resistance to lodging.
• Acceptability for yield and ear conformation.
• Processing quality.

Determine the length of harvest period possible with a limited number of varieties.
