Establishing yield loss in wheat cultivars with different levels of resistance in the presence of a range of infection levels of Fusarium pseudograminearum across different environments.

Grains Research and Development Corporation have funded a national five year project to establish the yield loss caused by a range of levels of foliar and root disease in cereal cultivars with various levels of resistance/susceptibility.

Crown rot (Fusarium pseudograminearum) is a significant focus within this project with the aim to establish yield loss in wheat cultivars with different levels of resistance in the presence of a range of infection levels across different environments.
