INTERGRAIN variety Brumby has gained an Australian Premium White (APW) wheat classification in Australia’s Western and Southern cropping zones.
It is tipped to be a mid-maturing yield leader in Western Australia, where it will predominantly compete with AGT’s Scepter variety.
Brumby is described as being high yielding, and suited to a range of environments, including WA’s South Coastal areas.
Brumby is later maturing than Scepter, and has a slightly shorter growing season than InterGrain’s RockStar.
According to InterGrain wheat breeder Dan Mullan, Brumby has already proven popular with growers for its attractive disease-resistance and yield package.
“Brumby’s powdery mildew resistance is a key attribute, as it provides a tool to manage this critical disease, which significantly constrains South Coast wheat production every year,” Dr Mullan said.
“Its good yellow spot and stripe and stem rust resistances also add to the variety’s attractiveness.”
Dr Mullan said Brumby had demonstrated excellent yield consistency across a range of WA seasons and sowing dates, highlighting its broad adaptability and capacity to respond to a range of seasonal conditions.
Brumby has a provisional falling number index of 4 on WA’s Department of Primary Industries and Regional Development (DPIRD) scale.
This is based on InterGrain’s internal preliminary falling number assessments.
While further testing is required, the provisional rating places the variety on a similar level to AGT variety Mace.
Brumby is comparable to Rock Star in its good grain size and test weight, and also has a longer coleoptile.
Its tillering capacity means it is expected to provide adequate weed competition.
Stocks of Brumby available for planting in 2022 have already sold out, and Dr Mullan said interest in it has been “exceptional” because of its resistance to powdery mildew.
Following results from trials as IGW6683, InterGrain submitted an application to Wheat Quality Australia (WQA) to have the variety approved for acceptance for APW classification.
WQA last week advised InterGrain the application had been successful.
