When choosing individual plants for restoration populations, there is potentially a trade-off between maximising genetic diversity (‘adaptability’) and selection for desirable properties (‘adaptation’). This project aims to develop pioneering methods to quantify this trade-off, and facilitate the design of optimised populations, with a focus on two Australian rainforest trees that are being impacted by myrtle rust infection: Rhodamnia argentea and Rhodamnia rubescens. By studying the genetic variation in each species, and how this relates to myrtle rust resistance and climate, this project aims to design populations that are genetically diverse, maximally resistant to myrtle rust, and adapted to future climate.

在为恢复种群选择单个植物时，可能会在最大化遗传多样性（“适应性”）和选择理想特性（“适应性”）之间进行权衡。该项目旨在开发开创性的方法来量化这种权衡，并促进优化种群的设计，重点关注两种受到桃金娘锈病感染的澳大利亚热带雨林树木：阿根廷罗丹尼亚和rubbescens罗丹尼亚。通过研究每个物种的遗传变异及其与桃金娘锈病抗性和气候的关系，该项目旨在设计遗传多样性，最大限度地抵抗桃金娘锈病，并适应未来气候的种群。
