A field method to assist selection of wheat varieties best suited to local soils may be the best strategy for mitigating waterlogging risk.

Waterlogging is a major constraint to wheat yields in Australia. There is genetic diversity for waterlogging tolerance in wheat and there is a need to improve wheat yields on waterlogging prone soils through identification of more tolerant varieties. This study aimed to (i) assess the usefulness of redox potential (Eh) and canopy temperature (Tc) to explain wheat responses to waterlogging and; (ii) determine whether there is sufficient variability in current, commercially available wheat varieties to justify trials on local, waterlogging prone soils. Ten varieties were examined, with control and waterlogged treatments imposed at two sites. Waterlogging was imposed at anthesis, with water ponded on plots for 14 days. Measurement of Eh allowed differences in the responses of varieties to waterlogging at the two sites to be understood. Canopy temperature was also useful at showing differences between the varieties. There were clear differences in the responses of currently recommended wheat varieties to both soil type and to waterlogging. Local trials on waterlogging prone soils are needed to allow wheat growers to select the best varieties for their soils.
