Retaining open pollinated canola seed on-farm locations
Aims

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

Key messages
  • At Merredin in 2018 the OP TT canola variety ATR Bonito produced similar yields and higher oil than hybrid TT’s.Retaining ATR Bonito seed ‘on-farm’ for 4 years produced similar yields, oil and financial returns to purchasing new 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.
