Variety trials

In the Willamette Valley, the adoption of quinoa in cropping systems has been hampered by production, processing and marketing difficulties. To help address those challenges, Extension tested 17 quinoa varieties and four planting dates to identify the most suitable options for the region. Researchers also tested harvesting and processing methods.

Quinoa Production for the Willamette Valley

This handout summarizes the results from clubroot resistant brassica (cabbage, broccoli, cauliflower, Napa cabbage, etc) variety trials conducted in 2015-16 on farms in the Willamette Valley of Oregon as well as in greenhouse screening trials.

The resistance to white mold obtained so far in snap beans has been derived from NY 6020, which provides partial physiological resistance. Under light disease pressure, plants will show few if any symptoms, while under heavy pressure, the plants may show a moderate level of infection (whereas susceptible BBL types will be 100% molded). Cultivars with this form of resistance would not need any supplemental control with fungicides, whereas under heavy pressure, fungicides might be required, but at a reduced frequency or quantity. The objective of this study was to determine whether OR6771 would benefit from an integrated mold control approach that included fungicides typically used in snap production, Topsin M and Rovral tankmixed.

Processors need broccoli with better quality traits than what is available in cultivars developed for California and Mexico fresh markets. Farmers need to reduce labor costs of broccoli production by mechanizing harvest. Most contemporary commercially available cultivars are not suitable for either mechanical harvest or processing. The objective of the OSU broccoli breeding program is to develop broccoli varieties adapted to western Oregon with suitable quality and high yields. The program operates on a one year cycle where cuttings from the field are taken into the greenhouse in the fall where they are rooted and hand crossed and self-pollinated to produce seed for the next generation. Seed is harvested in May and June and used to plant trials for fall evaluation. In 2015, nine experimental hybrids were planted in a replicated yield trial, which also included two commercial check hybrids and a new exserted commercial hybrid from Seminis.

Oregon is the second largest producer of processed green beans, and cultivars are needed that are adapted to western Oregon. The types that have traditionally been used are the bush blue lake (BBL) green beans with high yields, excellent processing quality. On the other hand, then need improvement in plant architecture, disease resistance (especially to white mold), and are genetically isolated from other green beans. The primary objective of the OSU green bean breeding program is to develop high yielding and high quality BBL green beans with high levels of white mold resistance. In 2015, a yield and processing trial of 18 advanced lines was conducted. An additional commercial trial with 27 entries was also grown and evaluated. Seven advanced lines are undergoing intense scrutiny for release as the first partially white mold resistant lines commercially available.

It is difficult to find information on winter squash production and storage. This page aggregates resources relevant to Oregon winter squash growers.
