Adult plant resistance (APR) to cereal fungal diseases is an important trait for grain growers to consider when choosing varieties to sow. APR is provided by one or more ‘minor’ genes which are effective after the seedling growth stages.

APR can complement a fungicide strategy by protecting, from diseases such as rust, those parts of the plant most responsible for yield.

To assist growers in their variety decision-making and crop management processes, the Grains Research and Development Corporation (GRDC) has published an Adult Plant Resistance Fact Sheet.

The Fact Sheet offers important information on how APR works and its impact on fungicide strategies.

It also sets out the 2012 APR disease response of Australian bread wheat varieties to leaf, stem and stripe rust.

The publication is included in the November-December edition of GRDC’s Ground Cover magazine and can also be viewed and downloaded via www.grdc.com.au/GRDC-FS-AdultPlantResistance.
