Aims
To identify variety x sowing date combinations to achieve optimum flowering window.
Key messages
Early sowing opportunities may provide a great opportunity to maximise canola yield, but selection of the correct variety is important.
Understanding the drivers behind canola development will help to improve canola management and variety selection.
Varietal maturity ratings don’t always correlate with varietal phenology.
