To assess the performance of winter and spring wheat germplasm managed under three different levels of management (ANZAC 25 April sown).

• The winter feed wheat RGT Accroc (awned) was significantly higher yielding under all managements compared to other varieties tested and exceeded 10t/ha under high input management.
• In general, grazing (mechanical defoliation at GS30) had less impact on yield with faster developing cultivars which reached GS30 earlier in the season (e.g. Scepter, Nighthawk, RGT Accroc and DS Bennett) compared to the slower developing wheats (e.g. RGT Calabro, Tabasco and Manning).
• Septoria tritici blotch (STB) was the principal disease in the majority of varieties, however the varieties subject to stripe rust infection, Trojan and Scepter, saw the biggest improvement in yield (2.95t/ha and 1.63t/ha respectively) associated with greater fungicide input under the high management approach.
• Tabasco, a slow developing winter wheat from northern Europe with good disease resistance and standing power was significantly higher yielding under the standard input management compared to the high input management regime giving no yield response to additional fungicide, N or PGR input.
• Scepter under high input management was the highest yielding (9.03t/ha) quality milling wheat and was 13.4% lower yielding than the highest yielding feed wheat (10.42t/ha).
• Above ground dry matter available for grazing varied from 150kg/ha with the spring wheats to over 2000 kg/ha with the long season winter wheats.
