Wheat farmers plagued by boron toxicity can breathe a sigh of relief — help is on the way with the first crop variety released for its response to boron. BT-Schomburgk (boron-tolerant Schomburgk) was developed with financial assistance from growers through the GRDC.
BT-Schomburgk outyields its parent Schomburgk by at least 10 per cent on boron-toxic soils. It contains the boron-tolerant gene from Halberd and is a high quality Hard variety.
However, the new variety is more susceptible to leaf diseases, especially stripe rust, and is therefore primarily a variety for upper, middle and eastern Eyre Peninsula in South Australia and for the sodic soils of Western Australia where it will be less prone to attack from stripe rust.
