To asses optimum sowing date and variety type for Canola for the South West Slopes region of NSW
• There is wide phenological diversity in Australian canola varieties. From a 28 March sowing date the fastest variety, Nuseed® Diamond, started flowering on 22 June and the slowest variety, Hyola® 970CL (winter type), started flowering on 28 September, a difference of 98 days from sowing to start of flowering.
• The highest yield of 4.7 t/ha came from sowing fast (e.g. Nuseed® Diamond) and mid (e.g. Pioneer® 45Y25 (RR)) spring phenology types in mid-April to early May. Sowing the fast variety early (Nuseed® Diamond) resulted in significant frost damage, reducing yield and quality, as it started flowering in June.
• The winter varieties and the slow spring varieties had stable yield across sowing dates, but generally yielded closer to 4 t/ha.
• Open-pollinated (OP), triazine tolerant (TT) varieties yielded within 5% of hybrid non-TT varieties (with similar phenology).
In 2017 at the Wallendbeen experiment site, the highest grain yield came from sowing fast and mid spring canola varieties in mid-April to early May. Sowing slow spring and winter varieties early resulted in lower grain yield. This experiment will be repeated in 2018 with four extra varieties; Phoenix CL (winter), Archer (slow spring), Pioneer® 45Y91 (CL) (mid spring) and an experimental slow spring variety. There will also be experiments examining responses to the rate and timing of nitrogen in a winter and a mid spring variety.

Plant Breeders’ Rights (PBR)
Some crop varieties used in research trials may be covered by Plant Breeders' Rights (PBR). Users should confirm PBR status of relevant varieties by searching the IP Australia PBR database, http://pericles.ipaustralia.gov.au/pbr_db/ or Variety Central (http://varietycentral.com.au/) and contacting variety owners for further information if required. Where possible, varieties have been listed according to their registered PBR name, although OFT cannot and does not guarantee that the information is accurate or complete.
