It held a slight yield advantage over Westonia and H45 in the southern wheat belt. However, small grain screenings for H45 were higher than Westonia at later sowing and at higher nitrogen rates. Dr Anderson said if growers chose to replace Westonia with H45, the combination of late sowing and high nitrogen rates should be avoided. It also consistently produced a higher grain protein percentage at similar yields. The level of screenings was not different between the varieties.
Further testing is required to clarify the relative tolerance to sprouting of the three varieties.
