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 very high density of prostrate hairs,
- the yellow young leaves,
- the shoots with indistinct or flattened nodes,
- the large, non-uniforme light green adult leaves, entire or with three or five lobes, with a slightly open petiole sinus or with overlapping lobes, medium to long teeth with straight or convex sides, no anthocyanin coloration of veins, a twisted, involute on the edges, slightly goffered and blistered leaf blade, and on the lower side of the leaves, a medium density of prostrate hairs,
- the very long grape clusters, foxtail-shaped, sometimes fasciated on the tips,
- the round-shaped berries with skin that can become slightly pink when over ripe.

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: 9 days after Chasselas.
Grape maturity: mid-season, 3 weeks and a half to 4 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.

Ugni blanc is very vigorous. It is well adapted to varied training and pruning systems, as well as diverse cultural and environmental conditions (wide geographical area of cultivation). It is best if trellised, as it can be sensitive to the wind.

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.

Ugni blanc is sensitive to downy mildew and eutypa dieback. It is also very sensitive to root-knot nematodes when it is grown ungrafted in sand. On the other hand, it is not very susceptible to phomopsis and grey rot on the grape clusters.

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

The bunches are very large while the berries are small to medium in size. Depending on growing conditions, Ugni blanc can be used to produce relatively neutral and balanced dry white wines. It can also be used to make base wines to produce great quality spirits.

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

The eleven certified Ugni blanc clones carry the numbers 384, 478, 479, 480, 481, 482, 483, 484, 485, 486 and 638. A conservatory of more than 400 clones is in the process of being set up in the wine-growing region of Cognac; the first part was planted in 2006.
