Supersweet corn variety yield and processing trial

corn

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

Screening for sources of resistance to head smut in corn

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.

Evaluation of certain factors affecting yield and ear characteristics of sweet corn

corn

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.

Development of corn earworm, Heliothis zea, on corn in Oregon

corn

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.

Evaluation of supersweet corn varieties for the Treasure Valley

corn

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.
