Graham is a high yielding winter feed or milling wheat with a wide sowing window – late March until late June. It has a good disease resistance profile and it responds well to fungicides.
Graham is an exciting multi-purpose wheat variety, bred by Syngenta in France and developed in conjunction with Cropmark Seeds as head licensee. Graham has a different disease profile to UK bred feed wheat and yields well across all New Zealand regions.
It has a robust disease package and produces a big and heavy grain sample. In its first year of FAR trials, Graham produced outstanding yields across a wide range of sites with yields in Canterbury ranging from 11.3 t/ha on dryland – to 17.5 t/ha under irrigation in Methven.
Graham has stiff straw, but is a medium tall variety so will benefit from a moderate PGR program. It has an excellent disease profile, with low sprouting risk and early maturity. The ideal plant population for March/April sowing is 150 plants/m². For late May and June sowing, plant population should be increased to 200 plants/m².
Graham is an average to high yielding feed cultivar performing well under both irrigated and dryland conditions across all sites and regions tested.
