This trial is the second year of the trial series comparing the performance and response of two breeding lines (03198-18, named Kowari , and 06204-16, named Bilby ) and two benchmark varieties (Carrolup and Williams ) to changes in nitrogen and plant density in medium rainfall environments.
New variety Bilby (breeding line 06204-16) out-yielded Carrolup (by 0.3 t/ha), but did not out-yield Williams, and was between Williams and Carrolup in grain quality.
Similar to 2017, a mild finish to the growing season meant all varieties met Oat1 quality specifications, and reduced the response of varieties to changes in plant density and applied nitrogen.
