Objective:
To evaluate the yield and quality of different canola varieties.
Personnel:
J.A. Torrion, Eeusha Nafi, Daniel Porter, Simon Fordyce, Pat Carr
Summary:
Twenty-two canola varieties were planted on April 28th, 2021 and emerged on May 8th, 2021. The rest of the management is detailed in Table 1.
We planted this trial at uniform plant population, but with final plant count ranging from 8-10 plants/ft2 depending on germination performance (Table 2). Flower occurrences ranged from 176 (DG 200CL) to 170 (NCC101S) julian days. Plant height ranged from 49.7 in (CP930RR) to 59.2 in (InVigor L357P). The average plant height was 56.2 in. Lodging score ranged from 0% (DKTFLL21SC) to 81.7% (BY 6211TF). The average lodging percentage score was 30.1%. This study had minimal shattering. Yield ranged from 2639 lbs/A (CP9978TF) to 3559 lbs/A (InVigor L345PC). The average yield was 3158.9 lbs/A. The average test weight (TWT) was 51.8 lbs/bu. Oil percentage ranged from 44.4% (NCC101S) to 50.4% (CP930RR). The average oil percentage for all cultivars was 47.9%.
Shattering was minimal for all varieties in this trial.
