Australian barley crops are affected by a range of leaf and root diseases. Diseases constitute a significant limitation to sustainable barley production. Reducing impacts from diseases is important for reliable production of high quality barley. Some diseases are prevalent around Australia whereas others are of regional significance (Table 1). The lack of resistance in major varieties grown in Australia to diseases like scald, net blotches, leaf rust and powdery mildew (Table 2) can impact on yield and grain quality mainly through a reduction in grain size. Reduced grain yields and low malting quality reduce returns to growers and affect domestic and export marketability. Improvements are sought through the development of varieties with adequate levels of resistance to the range of important biotic stresses. A major objective in barley breeding programs around Australia is to develop varieties with improved combinations of disease resistances while maintaining or improving yield, quality and other agronomic traits.
