NY001 - Native Plant Production and Phytophthora dieback

Objectives of the project --To study Phytophthora fungus and to develop and implement improved methods for screening seedling and clonal material of native plants for resistance to/tolerance of Phytophthora species. Diseases caused by Phytophthora species pose a considerable threat to the successful large scale cultivation of Australian native plants for the nursery industry. The selection and propagation of disease resistant or tolerant material is, therefore, desirable. This project involved the isolation and identification of Phytophthora species causing disease assessment of their pathogenicity and the development of improved techniques for routine screening for resistance in major native nursery crops. Inoculation studies involved intact plants in field and glasshouse and in vitro, excised shoots, roots and tissue cultures.
