Canola agronomy – retaining hybrid seed locations

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

Key messages
  • The early growth of commercial and farmer retained canola seed appeared to be similar.
  • Jockey fungicide seed treatment improved the yield of farmer retained seed for the triazine and imidazolinone tolerant varieties.
  • The conventional variety Hyola 50 was consistently higher yielding when grown from commercial seed.
