Subject Overview: This subject outlines the methods used to identify pathogens causing plant diseases, the consequences of diseases for plant productivity; and plant breeding techniques used to identify and capture plant traits within populations. The links between these two areas are explored as plant breeders and pathologists seek novel genetic material capable of resisting or tolerating plant pathogens. The concept of Plant Biosecurity will be introduced where Australia’s plant resources are safeguarded through adequate security and quarantine. Topics covered include:
• taxonomy, identification and biology of the main groups of plant pathogens and abiotic causes of plant diseases;
• host pathogen relationships, and the nature of disease resistance and pathogenesis;
• methods to identify pathogens, and development of tools for diagnosis,
• the processes leading to plant disease epidemics and their evaluation;
• principles and methodology of plant breeding;
• basic population genetics and genetic development of quantitative traits;
• evolutionary processes and genetic variability of plant and pathogen populations;
• world-wide distribution and conservation of plant genetic resources;
• methods of breeding self– and cross-pollinating plants;
• the management and integrated control of plant diseases.
Practical work includes the identification and diagnosis of common diseases; and the development of skills in research techniques and methodology in plant pathology and plant breeding.
Objectives: On completion of this subject, students will:
• understand the importance of genetic resources;
• be familiar with the differences between self-pollinated and cross-pollinated crops;
• understand the principles and methodology of plant breeding and improvement;
• be familiar with the biology and taxonomy of the major biotic causes of disease;
• be aware of the factors leading to disease epidemics;
• be capable of diagnosing common diseases of agricultural and horticultural crops; and
• be able to formulate a practicable approach to integrated control in commercial species.
Assessment: Two-hour end-of-semester examination worth 40% of final marks; a one-hour mid-semester examination worth 20% of final marks; practical class assessments worth 20% of final marks; and an assignment comprising a collection of plant diseases worth 20% of final marks.
