Grapevine planting material represents a major investment and critical production asset for the Australian wine industry, but the genetic diversity that is present in Australia is poorly understood. Furthermore, while grapevine cultivars can be unequivocally typed by ampelography and/or genetic tests, clonal identification solely relies on the tracing of supply records to the point of origin. Such records are not always available or reliable, particularly for older accessions. Whole genome sequencing (WGS) provides the most highly detailed methodology for defining grapevine cultivars and more importantly, clones of those cultivars.
