There are several sources of variety comparisons. The Canola Council of Canada has compiled this short list as a first step in choosing a new canola variety.
1) WCC/RRC data. Seed registration trial data from the Western Canada Canola/Rapeseed Recommending Committee compares yield, maturity, lodging, height and blackleg ratings for varieties submitted since 1998. Farmers can get a summary based on first-year private and second-year public data. Rarely would any of these cultivars have been tested in the exact same set of trials. Contact Raymond Gadoua of the Canola Council of Canada at [email protected] or 306- 683-2403 and he can email the summary.
2) Crop insurance data. Alberta and Manitoba publish summaries of crop insurance yield reports by variety and zone. Read the 2010 editions online at www.agcanada.com/yieldalberta2010/for Alberta and www.mmpp.com/mmpp. nsf/mmpp_publications. html for Manitoba. These are based on grower responses, are field by field, and do not include other data such as maturity, lodging and disease resistance. The 2011 editions come out in February or March. To get Saskatchewan crop insurance yield data, go to www.saskcropinsurance.com, click on the “Crop Insurance” heading in the yellow bar at the top, then select “Sask Management Plus” to find yield by variety.
3) Prairie Canola Variety Trials. PCVT trials did not run in 2010, but 2009 results are online. Go to www.canolacouncil.org. Click on “Grow Canola” in the black banner at the top to find the Prairie Canola Variety Trials page, or enter “PCVT” in the search box at the top.
4) Provincial seed guides. Seed associations (seed. ab.ca, saskseed.ca,seedmb.ca) saskseed.ca,seedmb.ca) have been using PCVT data for their canola comparisons. The staff who compile the guides are looking for alternative third-party sources for their 2011 guides. Seed guides usually come out in December or early in the new year. Last year’s guides are online at the addresses above.
5) Check with local research groups. For example: BCGPA ran variety comparison trials at Fort St. John and Dawson Creek. Email Clair Langlois at [email protected] for results. Irrigation Crop Diversification Corporation (ICDC) in Saskatchewan does independent irrigated crop variety trials. The 2011 pamphlet of results should be ready by early January. The 2010 edition is online at www.irrigationsaskatchewan.com. Click on the ICDC page, then look for “Crop varieties for irrigation.”
6) Seed company data. Farms.com’s Yield Data Centre at http://yielddata2009.farms.com/is a central source of seed company trial data. Seed companies also post trial data on their own websites. For example, Bayer CropScience has results from its Demonstrative Strip Trials program at www.bayercropscience.ca/products/seed/in-vigor/performance/.
Dekalb runs field-scale farm tests that compare its varieties versus a leading competitor. For test results, go to www.dekalb.ca and click on “Yield Information.” Pioneer Hi-Bred posts yield comparison info at pioneer.com. Ask other companies if they also have trial data.
