Retaining canola seed locations
Aims

To determine if retaining canola seed leads to reduced yield, oil and financial return.

Key messages

Farmers can safely retain OP seed for at least two years

Retained and graded hybrid TT seed had lower % establishment, variability in flowering, higher % of sterile flowers, lower oil and yield – but in this environment with yields below 1.5 t/ha the effects were not large enough to reduce gross margins compared to purchasing hybrid TT seed.
