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 Cunderdin in 2018 hybrid TT’s sown at the same target density produced similar yields to OP TT.
  • With low seed costs, ATR Bonito retained for 2, 3 or 4 years produced equal highest gross margins of over $600/ha - Comparable to the high yielding hybrid Nuseed HyTTech Trophy.
  • 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.
  • At our three sites in 2018, 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.
