To investigate the plant density response to yield and oil content of TT and RR hybrid canola in comparison with open-pollinated canola
In stressed conditions canola yields and gross margins were reduced at plant densities above 20 plants/m².
Despite being higher yielding and producing higher oil than CB Telfer TT, the higher seed costs of hybrid triazine tolerant variety Hyola 450TT resulted in lower gross margins.
Hybrid RoundupReady cultivar Hyola 404RR produced the highest yields and oil at Mullewa in 2013.
Despite higher upfront costs Hyola 404RR also produced the highest gross margins.
