To independently assess the potential for current, newly released and varieties close to commercial release in various locations and environments.
This trial was sown into warm and moist soil on the 9th May, providing excellent conditions for establishment. The rainfall received was excellent (572mm GSR) and was consistent throughout the growing season, setting the trial up for a high yield potential.
Top 3 Varieties
Bannister was the highest yielding variety in this trial at 5.73t/ha. It is a mid-season maturing variety so the sowing window was ideal for this variety. It is a milling quality variety which shows a 15% yield gain over Carrolup. It is susceptible to Septoria so ideally suited to lower rainfall areas where disease pressure is less.
Wandering performed well but was 0.3t/ha behind that of Bannister. It is a feed variety that has gained good market acceptance for export into the horse racing industry. It is also susceptible to Septoria so again better suited to lower rainfall areas or can be managed by the use of fungicides.
Kojonup is a mid-season milling variety that has consistently shown to be better adapted to medium and high rainfall zones. Kojonup has performed well in this trial this year however in previous years at this site it has been well behind Bannister and Wandering for yield. It is also susceptible to septoria.
