Yield results from the 2023 Manitoba Crop Variety Evaluation Team fall rye and winter wheat testing locations are available to help producers with variety selection. In addition to yield, agronomic and disease-resistance information is shown in the variety description tables below.
Things to consider
Comparing yields: Data provided in the yield comparison tables below helps to make comparisons between varieties at each site. Use the statistical information provided in the grey-shaded area at the bottom of the table to see if differences between varieties are significant. To know if yield differences mean something, look at the significant difference (Sig Diff) for each site, indicated as ‘yes/no.’ If ‘yes,’ then yield differences between varieties indicate real differences. When a site has shown significant difference, the least significant difference (LSD) value is also shown. This indicates the number of bushels per acre (bu./acre) that varieties must differ by to be considered significantly different.

Comparing long-term yields: Yields at a single site in a single year can be a poor indicator of how the variety may perform in your field in 2024. Look at long-term yield data or yields collected over many years and locations to get a better indication of performance over a variety of environmental conditions. When choosing a new variety, it is a good idea to look at past Seed Manitoba guides to see how consistently a variety performs across years and locations.
Agronomic and disease resistance: Yield is important, but other characteristics like maturity, height, standability, winter hardiness and disease resistance are also critical to maximizing yield potential and quality.
Seed Manitoba 2024
Seed Manitoba 2024 will be available in early December. The guide will provide the 2023 small plot, replicated and unbiased information on post-registration variety performance of many crop types in Manitoba. Seed Manitoba is a collaborative effort between the Manitoba Seed Growers’ Association, Manitoba Agriculture, and the Manitoba Co-operator.
Anne Kirk is Manitoba Agriculture’s cereal crop specialist. Contributors to the early release
of this data include MCVET co-ordinator Chami Amarasinghe, University of Manitoba wheat breeder Curt McCartney, Agriculture and Agri-Food Canada plant pathologist Brent McCallum, as well as MCVET site contractors and funding agencies.
