Objectives:

1. Develop broccoli varieties adapted to western Oregon with the following attributes:

For the past several years a "stalk rot" disease has been afflicting commercial sweet corn fields grown in the Willamette Valley. The disease seems to have a pathogenic basis, but the exact causal agent is unknown.
Eighteen hybrids with se or su endosperm were evaluated for resistance to root/crown rot. Ears were also evaluated for processing quality.

Objectives: Characterize su and se sweet corn hybrids for reaction to root/crown rot.

Cooperator: M. Powelson, Botany and Plant Pathology

Objectives:

Large field tests of the close row beet production system was tested with the cooperation of Mr. K. Zielinski and Norpac in 1998.

Objectives:

Several root-invading plant pathogens have been found in symptomatic sweet corn roots, Fusarium oxysporum, F. solani, and Pythium species, but their involvement in the symptoms observed in the field was still unclear (Powelson et al., unpub.) in the spring of 2000.

Objectives:

Objectives for 2000:

• To evaluate the N uptake efficiency of sweet corn varieties.
• To evaluate the effects of several fall-seeded and overseeded (relay interplanted) triticale, fall-seeded triticale plus common vetch, and overseeded red clover, on yield of sweet corn fertilized at three rates of N. The cover crops follow snap beans with three rates of N.
• To evaluate the effect of the cover crops and the N applied to the sweet corn on the amount of nitrate leached below the root zone.

Objectives:

• Characterize su sweet corn hybrids for reaction to root/crown rot.

Cooperators:

Objectives:

• Breed Bush Blue Lake green bean varieties with high economic yield.
• Improve pod characteristics including straightness, color, smoothness, texture, flavor and quality retention, and combine with delayed seed size development.
• Incorporate white mold resistance, and improve root rot tolerance while maintaining resistance to bean common mosaic virus.
• Initiate populations to facilitate molecular marker assisted selection of desirable horticultural traits.
• Evaluate novel genetic traits of potential benefit.
