The aim of this work was to identify new wheat varieties for maximising grain yield in dry and drying seedbeds in the scenario of possible frost risks during the growing season at Wickepin.
In high yielding environment with yield potential around 5 t/ha, Cobra (AH) yielded similar to Mace (AH) in both May and June sowings. New variety Trojan (quality grade not yet known in WA) outyielded Mace by 8% across both time of sowings. Selecting two or three varieties with different traits should help to manage production risks and to achieve yield stability.
