Protocol For Testing Farm-Saved Seed

1) To ensure the highest confidence in the testing procedures, a sample of seed must be drawn across the entire lot of seed. This may be done a number of ways; however the best and most preferred method is to sample directly from a clean seed stream. This includes but is not limited to sampling as the clean seed is:

a) Coming off the cleaners. b) Being loaded into a truck.

c) Being transferred from the truck into a seed bin on farm. 2) A minimum four subsamples per one metric tonne (one sample per 10 bu.) must be drawn and mixed thoroughly (e. g. A five tonne lot will require 20 subsamples).

3) A lot may not be any larger than 20 tonnes.

4) A representative two kilogram sample is to be submitted to a lab on the Flax Council’s list of approved testing labs for Triffid testing (4×60 g).

5) Only seed testing negative may be used for planting

6) At harvest or delivery of the 2011 crop, the grower will be asked to provide a certificate of laboratory analysis that verifies the planting seed tested negative.

7) Any seed testing positive for Triffid must not be cleaned or planted. Growers with a positive result will be required to purchase certified flax seed.
