The Chardonnay clone Gingin was imported into Western Australia in 1957 and has become one of Australia’s oldest recognised Chardonnay clones. While its phenotypic similarity to other Chardonnay clones has been noted, its exact origins remained a mystery. The AWRI has established a robust methodology for Chardonnay clonal identification that harnesses the detailed information provided by whole-genome DNA sequencing. This genomic technology was applied to unravel the history of this important grapevine clone by sequencing samples of Gingin and other clones suspected to be related to Gingin, including Mendoza and OF Chard. The findings shed light on the origins of these Chardonnay clones, while demonstrating the utility of the clonal genetic identification technology.
