The Australian Grains Genebank (AGG) safeguards the plant genetic resources that underpin agricultural grain crop production for Australia. Like most genebanks around the world, the AGG has the mandate to acquire, conserve, maintain and distribute germplasm, and operates in accordance with Australia’s obligation under the International Treaty on Plant Genetic Resources for Food and Agriculture. The AGG was established in 2013 through an amalgamation of three previous genebanks to now be custodian to one of the largest and most diverse collections of temperate and tropical grain crop species globally including cultivated, landrace and wild relative species. The AGG now operates as a Strategic Partnership between the Grains Research and Development Corporation and Agriculture Victoria that is spearheading the application of applied genomic and digital innovation to enable more effective, efficient, and cost sustainable genebank management and increased accessibility to industry. The process of transferring the three precursor genebanks to Horsham was a straightforward amalgamation process on paper. In reality, a unique set of challenges and opportunities arose that covered pre-planning, coordination, historical processes and protocols, the move in day, as well for the ongoing operating environments. This presentation will explore these challenges and opportunities and will discuss the learnings along the way in what was a mammoth effort by many people to establish the AGG as a world-class facility for the preservation of grain genetic diversity, ensuring its pivotal role in advancing sustainable agriculture, breeding innovation, and food security for future generations.
