Accelerated genetic improvement of wheat is imperative to meet the demands of a growing global population in an era of changing climate. We established the OzWheat genome-to-phenome (G2P) platform to support wheat research and pre-breeding, by providing an understanding of complex traits and genetic targets for breeding. Through pedigree information, a panel of 285 lines was curated to represent global genetic diversity and important landraces, parents and cultivars from Australian wheat breeding programs.

This panel was used to generate a large data resource, including expansion to new genetic diversity. Data such as genome-wide sequence haplotypes, multi-environment gene expression variants and trait measures from multi-year field and controlled conditions, provide a high-resolution platform for gene and allele discovery.

We demonstrate the power of the OzWheat G2P platform to identify important genetic variants, and development of data visualisation tools to ensure ongoing accessibility of the platform. This provides the wheat research and breeding community a valuable resource to support cultivar development into the future.
