DNA-Based Grape Variety Identification

Foundation Plant Services offers DNA-based grape variety identification on a fee-for-service basis. Using "DNA Fingerprinting" technology, varieties are identified by comparing the DNA profile of the client's sample to Foundation Plant Services' Grape DNA Identification Reference Database, which contains DNA profiles of varieties from the major grape growing regions around the world. Profiled varieties include wine, table, raisin, hybrid, and rootstocks. The service does not distinguish between bud-sports (somatic mutations, clones) within a given variety.

Standard Samples

Dried young leaves are our standard sample. Collection materials and collecting instructions are provided as part of the service. The service is available to both domestic and international clients. There is a $50 per sample surcharge for all international samples. Results are typically ready in four to five weeks.

Non-standard Samples (not available for international customers)

Plant variety can also be identified using other parts of the plant such as the fruit or dormant cuttings allowing samples to be tested in any season. Collection instructions for non-standard sample types are provided case-by-case. There is a $50 per sample surcharge for all samples types other than leaves dried using our standard protocol.
