Comments	Bianchetta trevigiana is a white wine variety from northern Italy. The name means 'little white grape from Treviso' (a city in the Veneto). Antonio Calò et. al. in Vitigni d’Italia state that Bianchetta trevigiana is a different grape variety than Vernaccia di Oristano and Vernaccia di San Gimignano. The name Vernaccia is commonly associated with several grape varieties in Italy and shares the same word root as the Latin word for 'vernacular'. The widespread usage of the word Vernaccia has caused confusion in regard to identification of grape varieties. The single name 'Vernaccia' or 'Vernaccia bianca' has in the past been used as a synonym for more than one grape variety (including Bianchetta trevigiana). Although the use of the word Vernaccia as a synonym for multiple varieties has caused confusion, it is included here to allow NGR users to more easily locate the variety known by the prime name Bianchetta trevigiana. The selection formerly known at FPS as Vernaccia FPS 01 was determined by DNA analysis in 2008 to be Bianchetta trevigiana. The name of the FPS selection was changed accordingly.

How Selection Numbers are Created

Questions are often asked as to how Foundation Plant Services (FPS) decides which number to assign to the grape selections in the foundation vineyard and whether those numbers relate to particular clones that may be the sources of the FPS selections.

The answer for most selections in the FPS foundation vineyard is that selection numbers are assigned by the next available (unused) number in sequence for that variety. There is nothing magical about it. For example, the first Sauvignon blanc selection that came to FPS in 1958 was named Sauvignon blanc FPS 01. The next Sauvignon blanc arrival received the name Sauvignon blanc FPS 02. Gaps in the numbering system in the current list of available selections mean that the omitted number was taken out of circulation for some reason, such as death from disease.

FPS intentionally chose the word "selection" rather than "clone" when referring to the products offered in the foundation vineyard. The word "clone" can be confusing and ambiguous. The major European collections have formal evaluation protocols for grape material to qualify material for release as an official "clone". Evaluation criteria includes field performance and wine making characteristics.

FPS does not perform formal clonal evaluations on the grapevine materials accepted for the foundation vineyard. The word "selection" at FPS simply means the material was collected from a single source vine from the vineyard of origin, whether within the United States or from a foreign vineyard. Some of our numbered selections have been through trials here in California but FPS does not conduct those trials or evaluations.

Having said that, there is a subgroup of selections at FPS that are official numbered clones from the formal clonal development programs in Europe. Those official clones are imported and sold by the owners as proprietary (trademarked) clonal material in the United States. The owners are large government or nursery entities in Europe, such as the ENTAV-INRA® clonal material from the IFV program in France. In order to preserve the identity of those clones, FPS agreed to assign them the same official clone number that the program in Europe gave them when released there. Cabernet Sauvignon 685 from France received the name Cabernet Sauvignon ENTAV-INRA® 685 at FPS. The owners of those proprietary clones are the ones who vouch for or affirm the authenticity of their trademarked clones.

Lastly, there is a small subset of "clones" that came to FPS in the 1980's prior to the establishment of the trademark programs for the European clones. Those clones also came to the United States associated with clone numbers assigned when the clones were developed in Europe. Many of the French clones in that group were developed at Dijon in France and the material has been known as the "Dijon clones". Those French clones were not protected by an official trademark program at the time they came to the United States. Some of those clones are no longer used in France and some were incorporated into the ENTAV-INRA trademark program.

FPS refers to this subset of clones as "generic clonal material". FPS agreed that we would assign those non-proprietary clones a new number at FPS rather than the European clonal number. They received their FPS numbers using the "next in order" rule. We may have a note on the plant description that the selection is "reported to be a certain French clone number". FPS cannot guarantee that such a selection is the official French clone number that it was formally associated with in France.

Registration Status	Registered Registered is the ultimate status in the California Department of Food & Agricultures Grapevine Registration & Certification Program. Registered selections have successfully completed all disease testing required by the regulations. Registered selections have also been confirmed as true to variety by experts using visual observations, DNA-based testing or both.

Comments	This selection arrived at FPS from Italy in 1981 with the name 'Vernaccia di San Giminiano'. It was initially given the name Vernaccia FPS 01 and first appeared on the list of registered varieties in 1989. Subsequent ampellographical identification in 2000 and 2001 suggested that the selection was most likely a different variety. The vines were put on a "distribution hold" at FPS in 2002 pending confirmation of identity by DNA analysis. A DNA analysis in 2008 revealed that the true identity of the selection is Bianchetta trevigiana, a variety unrelated to Vernaccia di Oristano and Vernaccia di San Gimignano. The name of the selection was changed in 2008 to Bianchetta trevigiana FPS 01. Additional information about the history of this selection can be found in the FPS Grape Program Newsletter, October 2008, which can be accessed on-line at http://fps.ucdavis.edu, under Publications.
