Through successful identification of mechanisms and molecular characterisation of resistance to Peronospora parasitica races and the identification of sources of host resistance against these races, breeders, for the first time, will be able to develop cultivars with resistance against the full spectrum of P. parasitica races occurring across southern Australia. Benefits include prevention of severe losses in canola from downy mildew, and more viable and sustainable production with less reliance upon fungicides. This research addresses the National Research Priority 'An Environmentally Sustainable Australia' and the Priority Goal of 'Transforming existing industries', and will particularly benefit southern Australian rural communities.

通过对霜霉小种抗性机制和分子特征的成功鉴定，以及对这些小种的宿主抗性来源的鉴定，育种者将首次能够开发出对整个澳大利亚南部发生的全谱霜霉小种具有抗性的品种。 其益处包括防止双低油菜因霜霉病而严重损失，以及更可行和可持续的生产，减少对杀真菌剂的依赖。 这项研究涉及国家研究优先事项“环境可持续的澳大利亚”和“改造现有产业”的优先目标，将特别有利于澳大利亚南部的农村社区。
