The OzWheat diversity panel is a curated collection of 285 wheat accessions representing global genetic diversity and the breeding history of Australian wheat. It spans material from historical landraces to modern cultivars, including key international introductions and donor lines. Designed to maximise phenotypic diversity, the panel underpins gene discovery and marker development for any trait of interest. Genotyped with high-density SNP and transcriptome data, the OzWheat panel provides a powerful genome-to-phenome platform for accelerating genetic discovery and breeding innovation, enabling the development of wheat varieties with improved resilience, productivity, and quality tailored to Australian farming systems.
