2014 CPS Local Performance Checks Managed by the CPS Research and Development team, Local Performance Checks (LPC) are used to provide data reference points for field agronomists and producers. Each site is a small plot site with replicated trials. All varieties on each site are seeded the same day and receive identical treatments of fertilizer, seed treatment, herbicides and fungicides. Local sites include Alberta Calmar Dawson Creek St. Albert Vulcan Westlock Saskatchewan Elrose Lake Lenore North Battleford Rosetown Rosthern Manitoba Glenboro Portage VT 500 G PV 530 G VR 9561 GS VR 9562 GC PV 533 G DK 74-44 BL 1.2 1.5 2.1 1.9 1.5 2.1 Saskatoon Watrous White City 2014 LPC Standability ratings Standability ratings Standability Standability is a measure of the crop’s ability to resist lodging. It is a result of plant breeder selection coupled with the influence of balanced fertility, agronomic management and the environment. While lodged crops may still have high yield potential, they are much more difficult to swath and combine. Strong-standing hybrids swath and combine more efficiently. Selecting a hybrid with a lower standability rating results in less wear-and-tear on the equipment and the operator, with more acres harvested each day. Canola hybrids with excellent standability can be swathed higher, leaving more stubble. A better-anchored swath will protect against pod shattering or complete swath loss due to wind and also improves snow capture.

The first hybrids to flower were PV 533 G and VR 9562 GC; the last hybrid to flower this season was VT 500 G. The latest maturing hybrid in the trials was VT 500 G which was a full day later than VR 9562 GC and approximately 1/2 day later than PV 530 G and PV 533 G. The benefits of a range of flowering and maturity dates include a reduction of risk for heat blasting, frost, insect damage and fungal infection, and an increased ability to plan and be efficient at harvest.
