Retaining hybrid canola seed locations
Aims

To compare the performance of commercial hybrid seed against farmer retained (F1) seed using conventional, triazine and imidazalinone tolerant varieties.

Key messages
  • Early growth of commercial, retained and mix seed treatments was similar.
  • In 2013 fluquinconazole had no effect on the yield for any of the varieties.
  • The conventional variety Hyola 50 was consistently higher yielding in 2013 (and 2012) when grown from commercial seed.
  • The triazine tolerant variety showed no yield difference among the different seed sources in both years of trials.
  • Significant yield reductions can result from retaining hybrid seed of some varieties.
