beans

Objectives:

  • To test interspecific hybrids previously obtained for disease resistance.
  • To design methods to redifferentiate plants from bean tissue culture by examining the effects of novel hormone metabolites recently isolated from bean embryos.

Objectives:

  1. Test carrot breeding lines developed in the U.S. Department of Agriculture carrot breeding program for resistance to the motley dwarf virus complex.

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.

Green Bean Breeding and Evaluation

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

  • Improved yield potential 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

Effect of cultural practices on yield, head rot and downy mildew of broccoli

OBJECTIVES:

  • To evaluate the effect of plant spacing on yield and disease incidence in broccoli
  • To evaluate the effect of nitrogen rate on yield and disease incidence in broccoli

Transfer of Genetic Resistance via Interspecific Hybridization and Tissue Culture Manipulation of Beans

beans

Objectives:

  • Transfer disease resistance and other desirable traits from runner beans, tepary beans to common beans using interspecific hybridization.
  • To study the redifferentiation of plants from bean tissue cultures.

Effect of cultural practices on yield and head rot of broccoli

broccoli

OBJECTIVES:

  • To evaluate the effect of plant spacing on yield and disease incidence in broccoli
  • To evaluate the effect of frequency and amount of irrigation water on yield and disease incidence in three broccoli cultivars
  • To evaluate the efficacy of Kocide 101 on control of head rot of broccoli under different irrigation regimes
