Comparison of canola varieties with delayed direct harvest at Gibson locations
Aims

To determine if canola cultivars vary in their rates of shedding

  • The greatest proportion of losses occurred at harvest.
  • The podguard variety IH51RR had significantly less losses than other varieties both before and at harvest.
