Winter Canola Varieties
Why you should consider winter canola in your crop rotation.
Winter canola is generally grown in a summer fallow winter wheat rotation or under irrigation. Several advantages make it an attractive option:
- Adding winter canola to a wheat rotation improves subsequent wheat yields, increases water infiltration and reduces soil erosion.
- Roundup Ready winter canola allows control of serious weed problems in repetitive wheat production.
- Roundup Ready winter canola fits well into chem-fallow growing systems.
- Conventionally bred winter canola allows for excellent grass weed control and allows for a different herbicide class in the rotation.
- Sulfonylurea and Imidazolinone tolerant varieties that overcome certain herbicide plant-back restrictions are now available.
- A deep taproot efficiently utilizes subsoil water and nutrients.
- Irrigated winter canola requires little water in the summer, allowing limited water resources to be directed to other crops during the growing season.
The following table lists the most common winter varieties planted in the western region.

NS = Not Stated
SURT = Sulfonylurea Residue Tolerant
Imi & SU = Imidazolinone and Sulfonylurea residue tolerant. *SU tolerance in PNW soils not fully tested.
RR = Roundup Ready, LL = Liberty Link, CL = Clearfield
Brassica napus, also known as Argentine canola, is most common. Tends to be high yield and later maturity.
Brassica rapa, also known as Polish canola, is typically shorter season than B. Napus.
Brassica juncea has early maturity with yellow seeds.
|HyClass 115 and 125||Can be planted in fields with history of Sulfonylurea (SU) use but SU herbicides cannot be applied post emergence.|
|Visby||Limited seed availability for 2014 planting. Please contact Brian Calbeck for seed at (270) 316-4316.|
|Largo||Earliest of the locally available winter varieties. Suitable for double cropping in long season areas.|
|Edimax CL||Clearfield Production System. Imidazolinone and Sulfonylurea (SU) residue tolerant but SU tolerance in PNW soils not fully tested.|
|Claremore||Imidazolinone and Sulfonylurea residue tolerant but not approved for Beyond application.|
|Amanda & Athena||Excellent bolting resistance. Can be planted in late spring or early summer and grazed.|
