Grass Patch, WA
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.
