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.

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.

Days to Flower and Days to Maturity
Growing hybrids with a range of flowering and maturity dates will:
• spread out the summer flowering period (a sensitive time for yield development)
• spread out the work load (fungicide applications, swath timing, harvesting)
Days to flower varied by 1.7 days between the longest and the shortest day variety. 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.
