Variety Testing

Variety testing field.

The Washington Oilseeds project host large-scale variety strip trials of winter and spring canola in the Pacific Northwest each growing season. The large-scale variety trials are used to study the performance of canola varieties at the field scale across the region. In addition to measuring yield, these variety trials are used to analyze the effects of stand establishment, pod count, and nutrient status on yield. The University of Idaho also hosts regional variety trials which can be found here [For Growers | Brassica Breeding & Research | University of Idaho (].

Variety Testing Program Needs Canola Seed

Jesse Ford is the new extension oilseed agronomist at Washington State University and is working to expand the oilseed variety testing program. Previously, Jesse was a graduate student under Dr. Isaac Madsen at WSU and assisted with Dr. Madsen’s variety trial work. Jesse also has experience working in the variety testing program at the University of Illinois. The variety testing program is intended to provide Washington state canola producers with unbiased analysis of canola cultivar performance in the region.

This year we anticipate placing 5-10 small plot variety trials and 2-4 large scale variety trials for spring canola this year across eastern Washington. Exact locations of all trials are currently fluid, but the expectation is that trials will be placed within a region extending from Davenport to Spokane and down to Pullman and Walla Walla, representing the majority of dryland canola production in Washington. Yield, oil content and other data will be collected from the trials and posted on the WOCS website following harvest. Each variety trial will likely be the site of an extension field day.

Seed requirements are 3 lbs. per variety for small plot trials and 35 lbs. per variety for large-scale trials. Ideally, we would like nontreated seed samples. If nontreated seed are unavailable, please submit treated seed. Seed should be delivered to 303 6th St, Davenport, WA 99122 by March 15th.
