Mullewa trials - oilseeds of WA canola varieties locations

To compare various canola varieties including RR (Roundup Ready) and TT (Triazine Tolerant) lines.

Key messages
  • The TT OP canola system presented the most profit and least expense option in this dry season.
  • Deciding to use hybrid technology should be aimed at early starts and higher rainfall years to improve return on in-vestment for the farmer.
  •  Both RR and TT systems provided excellent weed control.
  • TT hybrids exhibit handy tolerance of warm dry conditions at the finish of the season.
