Disease and related disorder management

Green Bean Breeding and Evaluation

Objectives: 1. Breed Bush Blue Lake green bean varieties with high economic yield and improved plant architecture. 2. Improve pod characteristics including straightness, color, smoothness, texture, flavor and quality retention, and combine with delayed seed size development. 3. Incorporate white mold resistance and improve root rot tolerance. 4. Develop a molecular marker map to facilitate marker-assisted selection of desirable horticultural traits.

Management of Fusarium diseases of sweet corn in the Pacific Northwest

Corn

Objective 1: Evaluate sweet corn inbred germplasm for colonization of silks by Fusarium species and subsequent seed infection/contamination. Objective 2: Evaluate biological applications to silks and subsequent Fusarium presence in ears. Objective 3: Evaluate seed disinfestation and location of remaining Fusarium on or in seed. Objective 4: Examine the yield and disease levels of sweet corn plants grown from seeds treated with germicidal light.
