Description 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.

The identification is based on:
- the tip of the young shoot with a medium to high density of prostrate hairs and a piping distribution of anthocyanin coloration,
- the green yellow young leaves, with a medium density of prostrate hairs and a low density of erect hairs,
- the thin red shoots,
- the small adult leaves, entire or with five lobes, with an open V-shaped petiole sinus, moderately long teeth compared to their width at the base with straight sides or with one side convex and one side concave, ellongated star-shaped main veins (with the five corresponding teeth that are prominent and clearly longer than the others compared to their base), a weak to moderate anthocyanin coloration of veins, a shiny, involute, folded, slightly goffered and roughly blistered leaf blade, and on the lower side of the leaves, a low to very low density of erect and prostrate hairs,
- the round-shaped or obloid berries.

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.

Cultivation and agronomic skills

The data on suitability are the result of field observations or, if none are available, of bibliography mining and the study of bibliographic references.

Silara has a horizontal or semi-erect bearing and looks like its leaves have been thinned out. This variety is fertile and produces a lot of grappillons that can almost be a second harvest. Silara is sensitive to potassium deficiency and chlorosis.

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.

Silara is sensitive to powdery mildew and moderately sensitive to phomopsis. This variety is not very affected by vine leafhoppers and by bud mite disease.

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)

Bud burst: 13 days after Chasselas.
Grape maturity: mid-season, 3 weeks after Chasselas.

Technological potential

The size of grape clusters and berries indicated are based on the following scales: - Wine grape varieties Size : Very small Bunch (g) : ≤ 100 Berry (g) : 1 - Table grape varieties Bunch (g) : 150 Berry (g) : 2 - Wine grape varieties Size : Small Bunch (g) : 100 - 200 Berry (g) : 1,5 - 2 - Table grape varieties Bunch (g) : 150 - 250 Berry (g) : 2 - 3,5 - Wine grape varieties Size : Moderate Bunch (g) : 200 - 250 Berry (g) : 2 - 2,5 - Table grape varieties Bunch (g) : 250 - 400 Berry (g) : 3,5 - 5,5 - Wine grape varieties Size : Large Bunch (g) : 250 - 400 Berry (g) : 2,5 - 3,5 - Table grape varieties Bunch (g) : 400 - 700 Berry (g) : 5,5 - 8 - Wine grape varieties Size : Very large Bunch (g) : 400 Berry (g) : 3,5 - Table grape varieties Bunch (g) : 700 Berry (g) : 8 Remarks concerning the characteristics of the wines are generally based on tastings organised by juries of professionals.

Silara's bunches are small to medium in size and moderately compact. The berries are medium, with a slightly foxy flavor, a moderately thick skin and a fleshy pulp. Silara musts have a nice color potential, a pronounced acidity and a moderate sugar content.

Description des clones agréés en France

In this section, the list of certified clones is given. Information on clone conservatories is also provided.

  • Clone number
  • Brand
  • Origin

    Region, department or winegrowing region in which the “clone mother plant” was identified and selected.

  • Selection

    Body or bodies which selected the clone. In France, clonal selection is the responsibility of the selection organisations (themselves accredited by the ministry in charge of agriculture), usually in close collaboration with a technical partner working in a winegrowing region. For clones certified after 1999, the name of the partner or partners who took part in the selection work is also included. (NB: CA = Chamber of Agriculture).

  • Year of approval

    Year in which the clone was certified by the FranceAgriMer board further to a proposal by the Vine section of the CTPS (Permanent Technical Committee for Plant Selection).

  • Agronomic Reference

    Region, department or winegrowing region in which the agronomic and technological data were collected.

  • Surface in multiplication

    Surface area in hectares (ha) of stock nurseries used for propagation for the year under consideration (in brackets), which allows the available potential to be evaluated. Clones with a surface area of between 0.01 and 0.10 ha are shown as <0.10 ha. Clones of limited dissemination, but for which we have technical data, are shown as <0.01 ha. Other clones are given as “low-dissemination clone”, which means that the clone has been certified only recently or has not been propagated. In both cases, only the initial material is planted in the selection centres.
