Hello. My name is Professor Robert Park. I work at the University of Sydney Plant Breeding Institute where I hold the Judith and David Coffey Chair in Sustainable Agriculture. I'm also the director of the Australian Cereal Rust Control Program. Today I'm going to talk to you about biotic stress tolerance and resistance plants.
Today's lecture will cover, firstly, the importance of plant diseases, secondly, options for disease control, and thirdly, I will discuss the genetic control of plant pathogens. In this section, I will cover the terminology that we use in host pathogen interactions. For example, what is resistance and what its pathogenicity? I will also discuss the gene-for-gene hypothesis which is the foundation of almost all the work we do in resistance breeding. And then finally, I want to spend a little bit of time and talk to you about the wheat rust diseases and resistance breeding. This is an area that I've worked in for the past 30 years.
