AAC Brown 18 is Canada’s first hybrid condiment mustard with superior yield, greater seed vigour and weed competitiveness.
Special Note: Brown Elite is meant to replace Brown 18 moving into the spring of 2025. AAC Brown Elite yields very similar to AAC Brown 18, but Brown Elite is two days later than Brown 18 for maturity.
The Benefits of AAC Brown 18:
- Higher yields 120% of the check Centennial Brown
- Resistance to race 2a of white mold
- Good for straight cutting
- Strong black leg resistance
Days to Maturity: 89
Yield Comparison:
- AAC Brown 18: 120%
- Centennial Brown: 100%
Questions & Answers
How does mustard yield versus canola?
In 2022, a trial was done at Outlook, SK where AAC Brown 18, AAC Yellow 80, and Liberty Link 233P were grown under irrigation. Yield results for all 3 varieties were comparable. See Condiment Mustard Development for more details.
What is the difference between AAC Brown 18 and AAC Yellow 80?
AAC Brown 18 is a hybrid variety of Brown mustard (Brassica juncea) and is brown seeded. AAC Yellow 80 is a composite variety of Yellow mustard (Sinapis alba) and is yellow seeded. Plant Breeders’ Rights has been granted for AAC Brown 18 and has been applied for in the case of AAC Yellow 80.
What is a hybrid? Why should I use a hybrid?
(I’ve been brown bagging it for years and all is great!)
A hybrid is the product of a cross between genetically unlike parents. The seed produced by crossing fertile male plants created from one parent with sterile female plants created from a second diverse parent. The hybrid seed produced has been selected for heterosis or hybrid vigor such that certain characteristics (i.e. yield) are superior to both of its parents. Hybrid mustard has many benefits, the main one is an increased yield over open-pollinated varieties. Consistently AAC Brown 18 has yielded at least 19% greater than Centennial Brown. Other benefits of the hybrid include increased biomass accumulation, quicker emergence and ground cover, which can help the crop’s competitiveness with weeds.
What products can be used for weed control?
Growers can use:
- Authority for kochia control in all mustards
- Edge can be used in yellow mustard for broad leaf control
- Clethodim for grass control
- Muster Toss N Go in brown and oriental mustards
- Quinclorac in brown and oriental mustards
- Trifluralin in all mustards.
Follow label instructions on all herbicides used on mustards.

What Growers are saying:
Ron Goetz – AAC Brown 18
I farm in the Brooks area and in 2022 I grew AAC Brown 18 on some irrigated land that I have. Even with a light seeding rate, the crop came out of the ground and achieved ground cover quickly, which really helped with weed control. I was very happy with how the crop advanced, and it flowered quickly as well. When I harvested the crop I was surprised to see that despite a hot summer it yielded close to 50 bushels per acre and with the price of mustard at that time I was very happy with the return per acre.
For my operation I don’t feel I need to grow canola anymore, because it can’t take the hot summers like mustard can.
