Thesis title: Characterising canopy energy balance for heat tolerance in wheat

Supervisors: Thomas BUCKLEY , Helen BRAMLEY , Thomas SCHAEFER, Jose JIMENEZ BERNI

Thesis abstract:

Heat stress affects wheat in different ways depending on the climate. The damage can result in a yield decrease when heat events occur during critical stages, such as reproductive stage or grain filling. Understanding the mechanisms occurring in plants when they are subjected to high temperatures will help to identify plant traits conferring heat stress tolerance. This goal can be achieved by characterizing the canopy energy balance. In this research, contrasting wheat genoptypes for heat tolerance will be planted in three different locations in Australia. To determine the canopy energy balance, the environment will be monitored and its interaction with those varieties. Furthermore, this research aims to overcome the technological challenge of measuring environmental variables by developing faster and more affordable systems and by the efficient use of technologies already available. The data gathered and traits identified will be implemented in crop simulation models to evaluate yield and phenology of the genotypes and also to define ideotypes based on trait value to help identifying breeding programs strategies in the future.«/div»
