Note on grapevine variety datasheets

Name of the variety in France
Name under which the variety is officially registered in the catalogue of grapevine varieties in France and under which it may be propagated and disseminated.
Origin
The geographical origin of the variety is specified or, if this is not possible, the area in which it is traditionally cultivated. The genetic origin of the variety is also indicated whenever it is known from hybridiser data or from genetic analyses published or obtained by the teams at INRAE in Montpellier (UMR AGAP) and Vassal-Montpellier Grapevine Biological Resources Centre (CRB-Vigne).
Synonyms
Recognised alternative names that may be used to identify the propagation material of the variety in France or in other member countries of the European Union.
Legal information
This information indicates on which list the variety is registered (A or B), whether it is classified for wine grapes, and in which member countries of the European Union the variety is also officially registered (for more information, see the "Legislation"menu).
Use
This information indicates the normal and statutory use for the grapes.
Evolution of cultivated areas in France
The figures provided are taken from vineyard land registers (IVCC, ONIVIT, ONIVINS), general agricultural censuses (SCEES-INSEE) and the current computerised vineyard register (DGDDI, FAM).
Regional vine planting data is available on the following site: visionet.
Descriptive elements

Only the principal ampelographic elements enabling the varieties to be characterised and identified are provided. They are presented according to the descriptor code recognised by the International Organisation of Vine and Wine (OIV), the International Union for the Protection of New Varieties of Plants (UPOV), the Community Plant Variety Office (OCVV) and Bioversity International (for more information, see the "Ampelographic glossary" menu).
The photographs of leaves and grapes were taken in natural conditions, on the vine, in very similar situations in terms of growing conditions (sandy soil, Mediterranean coast):

  • Domaine de l'Espiguette (IFV), Le Grau du Roi (Gard),
  • Domaine de Vassal (INRAE), Marseillan (Hérault),
  • La Gaillarde Campus (Institut Agro | Montpellier SupAgro), Montpellier (Hérault).

Only a few photographs, including the tips of bunches, were taken in other conditions.

Genetic profile
The genetic profile of the variety is provided for the 9 microsatellite markers (or SSR markers) selected under the European programme GrapeGen06 (http://www.eu-vitis.de/index.php) and by the OIV. The absolute size values of the alleles may vary slightly from one laboratory to another, but the relative differences between the two alleles of one single microsatellite are constant. The genetic analyses were conducted by the INRAE Montpellier team (UMR AGAP) and the IFV’s Plant Material Centre.
Phenology

The growth stages indicated are the result of obsrvations made at the Domaine de Vassal Estate where the set of these varieties form a collection. The results are indicated compared to the Chasselas vine variety as a reference in order to make comparisons between years and different sites. As such, for information purposes, the dates for the Chasselas B growth stage at Domaine de Vassal are as follows:

  • Bud burst, 21 March (average over 50 years)
  • Grape maturity, 14 August (average over 50 years)
Suitability for cultivation and agronomic production
The data on suitability are the result of field observations or, if none are available, of bibliography mining and the study of bibliographic references.
Susceptibility to diseases and pests
These remarks are also the result of field observations or, if none are available, of bibliography mining and study of bibliographic references.
Technological potentiality

The size of grape clusters and berries indicated are based on the following scales:

  Wine grape varieties Table grape varieties
Size Bunch (g) Berry (g) Bunch (g) Berry (g)
Very small ≤ 100 < 1 < 150 < 2
Small 100 - 200 1,5 - 2 150 - 250 2 - 3,5
Moderate 200 - 250 2 - 2,5 250 - 400 3,5 - 5,5
Large 250 - 400 2,5 - 3,5 400 - 700 5,5 - 8
Very large > 400 > 3,5 > 700 > 8

Remarks concerning the characteristics of the wines are generally based on tastings organised by juries of professionals.
