Descriptive elements

<p>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 <a href="/en/vocabulaire">"Ampelographic glossary"</a> menu).<br>
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):</p>
<ul>
<li>Domaine de l'Espiguette (IFV), Le Grau du Roi (Gard),</li>
<li>Domaine de Vassal (INRAE), Marseillan (Hérault),</li>
<li>La Gaillarde Campus (Institut Agro | Montpellier SupAgro), Montpellier (Hérault).</li>
</ul>
<p>Only a few photographs, including the tips of bunches, were taken in other conditions.</p>

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 young leaves, with a medium density of prostrate hairs on the lower side of leaves,
- the shoots with red internodes,
- the circular, dark green, adult leaves, entire or with three lobes, with an open V-shaped petiole sinus, short to medium teeth compared to their width at the base with straight or convex sides, a moderate anthocyanin coloration of veins, a hard, shiny, flat or involute, blistered, slightly goffered leaf blade, and on the lower side of the leaves, a low density of erect and prostrate hairs,
- the round-shaped berries with quite numerous lenticels.

Phenology

<p>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:</p>
<ul>
<li>Bud burst, 21 March (average over 50 years)</li>
<li>Grape maturity, 14 August (average over 50 years)</li>
</ul>

Bud burst: 5 days after Chasselas.
Grape maturity: mid-season, 2 weeks after Chasselas.

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.

Voltis is vigorous and has a semi-erect to erect bearing. This variety is moderately fertile and must be pruned long. Voltis' shoots are a little susceptible to node breaking and this variety can be sensitive to magnesium and potassium deficiency.

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.

These remarks are also the result of field observations or, if none are available, of bibliography mining and study of bibliographic references.

Voltis is resistant to downy mildew and to powdery mildew, but it is sensitive to black rot.
