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 low to very low density of prostrate hairs,
- the green yellowish young leaves,
- the short internodes,
- the adult leaves with three or five lobes, deep V shapes lateral sinuses with slightly overlapping lobes, a V shaped not very open or closed petiole sinus with overlapping lobes and often a tooth on the edge, long teeth compared to their width at the base with straight sides, no anthocyanin pigmentation of veins, a finely blistered, slightly twisted or involute leaf blade, and on the lower side of the leaves, no erect and prostrate hairs,
- the round-shaped or slightly obloid.

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: 8 days after Chasselas.
Grape maturity: late-season, 5 weeks and a half 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.

Uva biancona is a vigorous, very productive variety that must be pruned short. It has a semi-erect to erect bearing. The bunches can be preserved for a long time on the vine, up until November or December, without alteration. This variety is a little sensitive to coulure.

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.

Uva biancona is sensitive to esca and also seems to be quite sensitive to downy mildew. In some vintage, this variety can be susceptible to sour rot.

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

Uva biancona's bunches are large in size and compact. The berries are medium, simple-flavored, with a thick skin and a juicy pulp. Juice yield is low. The musts are a little sensitive to oxidation. The wines are low in alcohol, a strong acidity and neutral aromas. Uva biancona can be interesting to improve the liveliness in blends.
