Fresh Market Vegetable Production

Green Bean Breeding


Objectives: Breed bush green beans for the western Oregon processing industry with:

  • Improved potential for high yields at favorable sieve sizes and dependability.
  • Improved straightness, texture, and other quality factors.
  • Develop easy picking and small pod strains of Blue Lake type.
  • Resistance to white mold and root rot.

Fungicide resistance in Botrytis cinerea in snap beans, and chemical and biological control of gray and white mold of snap beans



  • Determine the distribution and frequency of benomyl and vinclozolin/iprodione resistance in the Botrytis population in snap bean fields located in the Willamette Valley.
  • Evaluate the efficacy of experimental fungicides for control of gray mold and white mold of snap beans.
  • Evaluate the efficacy of biological antagonists for control of gray mold of snap beans.

Control of Rust, Cercospora, and Mildew of Table Beets (1991)

  1. Evaluate the effectiveness of non registered chemicals (Bayleton, Folicur) and registered chemical (Sulfur) for the control of Rust, Leaf Spot, and Mildew in Table Beets (Uromyces betae, Cercospora beticola, Peronospora schachtii, and Erysiphe polygoni.)

Commercial Sorting of Supersweet Corn Seed for Assured Yield (1991)


Report to the Oregon Processed Vegetable Commission

Clint Shock, Erik Feibert, and Monty Sanders
OSU Malheur Experiment Station

Bob Trent
Crookham Seed Company


  1. The effects of seed class and seed density on supersweet corn plant stand, plant development, and yield were examined using a single lot of Crisp 'N Sweet 710. Seed class and seed density can be controlled in packaging supersweet corn seed and could provide a means to more reliable plant stand establishment.

Cauliflower Variety Observations (1991)


Report to the Oregon Processed Vegetable Commission

Jim Baggett and Jack Stang
OSU Dept of Horticulture


  1. Evaluate head quality, maturity time and total yield of 10 promising (based on 90-91 observations) cauliflower varieties at a wide range of planting times; relate timing of maturity to turning of curd initiation and the period between curd initiation and harvest; screen additional cauliflower varieties to identify those having head characteristics suitable for processing.
