LUARS Research 2022 – Results from Canola Varieties Experiments
Dr. Tarlok Singh Sahota CCA
Liberty Canola Varieties (Seeded on June 11, 2022):
Twelve varieties were evaluated; some of them new and half of which had Clubroot
resistance/or shatter reduction trait.
Delayed seeding (prolonged winter and wet May) and dry weather (total rainfall during
June and July 87 mm only) kept the seed yields low (trial mean 2.61 MT/ha). Growth as
seen from straw yield (7.69 MT/ha) didn’t get converted into seed yield.
Seed yield was in the order of LA344PC (3.34 MT/ha) ≥ L357P (3.09 MT/ha) = P501L
(3.09 MT/ha). Seed yield in other varieties ranged from 1.98 MT/ha in L340PC to 2.79
MT/ha in L252.
L357P recorded the highest straw yield (9.55 MT/ha). Straw yield in other varieties
ranged from 6.11 MT/ha in DKLL-82SC to 9.12 MT/ha in LA356PC.
Averaged over 2018-2022, three top seed yielding varieties were L252 (3.86 MT/ha),
P501L (3.01 MT/ha) and LA344PC (2.90 MT/ha). Straw yield was higher with L357P
(8.39 MT/ha) and LA344PC (8.12 MT/ha) than with the other varieties (6.12-7.61
MT/ha).
P stands for ‘Shatter Reduction’ and C for ‘Clubroot Resistance’.
Roundup Ready Canola Varieties (Seeded on June 11, 2022):
Eight varieties were compared for their production potential.
Three top seed yielding varieties were 6086CR (3.62 MT/ha), BY6204TF (3.24 MT/ha),
and CS2300 (2.89 MT/ha). Seed yield in other varieties ranged between 1.95 to 2.78
MT/ha.
Straw yield was highest with BY6204TF (11.82 MT/ha).
Averaged over 2020 to 2022 (7 varieties), CS2600CR-T (3.55 MT/ha), LR344PC (3.46
MT/ha) and BY6204TF (3.11 MT/ha) gave higher seed yield than the other varieties.
Highest straw yield was obtained with CS2300 (8.25 MT/ha) and BY6076CR (8.23
MT/ha).
CR stands for Clubroot resistance and TF for Truflex.
Clearfield Canola Varieties (Seeded on June 13, 2022):
Five varieties were compared for their production potential.
Seed yield was in the order of 5545CL (3.47 MT/ha) ≥ 2028CL (2.92 MT/ha) ≥
CS2500CL (2.82 MT/ha). Straw yield was highest (7.77 MT/ha) with 5545CL.
Averaged over 2021-2022, 5545CL produced the highest seed (2.85 MT/ha), straw (6.40
MT/ha) and biomass (8.92 MT/ha) yields.
Recommendations:
For rotation of herbicides and to avoid the problem of herbicide resistant weeds, Liberty
canola varieties should be grown. Considering both the seed yield and the straw yield,
L357P could be preferred over other varieties.
Those who wish to grow Roundup Ready canola, may choose CS2600CR/or LR344PC.
The latter has both the Liberty and the Roundup Ready traits.
Those who have concern for GM Technology/and want to crush canola for oil, may
prefer 5545CL, which has given consistently higher seed and straw yields as compared to
the other varieties.
