We recommend growers use DDLS seed testing service for accurate, internationally acredited testing of canola seed.
For more information about seeking a germination test from DDLS, use the 'See Also' links on this page, telephone 9368 3721 or email firstname.lastname@example.org.
As a secondary option, growers may choose to do their own germination test.
Canola germination test and calculating germination percentage
It is best to test each seed lot several times. Prepare for this when collecting the seed.
- Collect 50 seeds from each lot to be planted.
- Lay four sheets of paper towel on top of each other and moisten (do not drench).
- Place 50 seeds 10mm apart on the paper towels.
- Roll up, sandwiching the seeds between the moist paper towels.
- Soak a hand towel in water and ring out, then wrap it around the rolled-up paper towel and loosely secure with rubber bands.
- Place in a plastic bag, seal and place in a warm spot, such as the kitchen bench near a window, and leave for 5-7 days.
- Unwrap and count the number of seeds that have not germinated.
- Do your calculation as follows: Germination % = [(number of seeds tested − number of seeds that didn’t germinate) ÷ 50] ×100.
