Improving native seed quality

The goal of this project is to understand how genetic diversity and patterns of gene flow influence seed quality in Seed Production Areas for a selection of Australian plants commonly used in restoration.

Building resilient Seed Production Areas

The establishment of Seed Production Areas (SPA) for native Australian plants has become increasingly important to fill the gap between seed supply and demand. However, key knowledge gaps remain in understanding the genetic diversity and composition of SPAs compared to natural populations and how this translates to healthy seeds suitable for changing climates.

This is broad project using genomic and population genetic analyses, common gardens and glasshouse experiments, environmental DNA (eDNA) and theoretical modelling. As part of a collaboration with Greening Australia and other research groups across Australia, we aim to provide basic research findings and practical guidelines for improving native seed quality across diverse plant life histories, mating and pollination systems. Ultimately this will help standardise and guide SPA development to improve the likelihood of success and the production of genetically healthy seed appropriate for changing climates.
