Variety Descriptions

All variety descriptions other than yield are based on data from the Linseed Cooperative Trials in the Prairie provinces.
MCVET flax testing was done in partnership with the University of Saskatchewan Crop Development Centre across all three Prairie provinces in 2025.
All varieties are immune to rust.
All varieties are susceptible to pasmo.

¹Oil quality of flax is based on the amount of linolenic acid measured in the seed or as measured by iodine value which is calculated from the fatty acid composition of the seed. A higher iodine value and/or higher ALA content indicates a higher overall oil quality in the seed.
² E = Excellent; VG = Very Good; G = Good; FG = Fair to Good; F = Fair; PF = Poor to Fair; P = Poor.
