Trial location(s) Grass Patch, WA
Retaining open pollinated (OP) canola seed on-farm locations
Aims

To evaluate if retaining OP canola seed leads to reduced yield or oil.

Key messages
  • At Grass Patch in 2018 hybrid TT’s produced higher yields and gross margins than most of the OP TT canola variety ATR Bonito treatments.
  • Retaining ATR Bonito seed ‘on-farm’ for 1, 2, 3 or 4 years produced similar yields, oil and higher gross margins than purchasing new OP seed.
  • Using ATR Bonito seed stored for 4 years produced plants lacking in vigour and overall poorer performance than growing out and retaining seed each year or purchasing new commercial seed.
