Muscat Bleu

Origin

Muscat bleu or 83/2 Garnier was obtained by M. Garnier in Geneva, Switzerland, in the 1930's. Based on genetic analyses carried out in Montpellier, this interspecific hybrid probably comes from a crossbreeding between 15/6 Garnier (Villard noir x Müller-Thurgau) and Muscat de Saint-Vallier (20473 Seyve-Villard).

Synonyms

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 no or a very low density of prostrate hairs,
- the young leaves with bronze spots and no prostrate hairs,
- the shoots with red or red-striped internodes,
- the adult leaves entire or with three lobes, an open V- or U-shaped petiole sinus, large teeth, long compared to their width at the base with straight or convex sides, a low anthocyanin coloration of veins, an involute or sometimes twisted, finely blistered, slightly goffered leaf blade, and on the lower side of the leaves, no erect hairs and prostrate hairs,
- the round-shaped or slightly ellipsoid berries.

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: 1 day after Chasselas.
Grape maturity: early-season, same as 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.

Muscat bleu has a semi-erect bearing. This variety is moderately vigorous and it is better to plant it into fertile enough soils. It can be susceptible to coulure and/or millerandage in case of bad weather during flowering.

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.

Muscat bleu is tolerant to downy mildew and powdery mildew, but it must be grafted.
