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 tip of the young shoot with a low density of prostrate hairs,
- the green young leaves with bronze spots,
- the shoots that have long internodes,
- the circular, small to moderate adult leaves, with three or five lobes, an open U-shaped petiole sinus with parallel edges and often naked petiole veins, small to medium teeth with straight sides, no or a weak anthocyanin coloration of veins, a smooth shiny leaf blade, and on the lower side of the leaves, no erect and prostrate hairs,
- the narrow ellipsoid or cylindric 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.

The data on suitability are the result of field observations or, if none are available, of bibliography mining and the study of bibliographic references.
Dattier de Beyrouth is a vigorous variety with a semi-erect to horizontal bearing. It can be managed by short or long pruning but it must be carefully trained because the shoot base is fragile in the spring and the shoots are sensitive to the wind. Dattier de Beyrouth is also susceptible to coulure and millerandage.
These remarks are also the result of field observations or, if none are available, of bibliography mining and study of bibliographic references.
Dattier de Beyrouth is very susceptible to downy mildew and phomopsis. It is also sensitive to grey rot.
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: 9 days after Chasselas.
Grape maturity: late-season, 4 weeks and a half after Chasselas.
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.
The bunches are very large, loose or moderately compact. The berries are very large, simple-flavored, with a thick skin and a fleshy pulp. This variety has a good storage and transport capacity.
In this section, the list of certified clones is given. Information on clone conservatories is also provided.
The three certified Dattier de Beyrouth clones carry the numbers 304, 966 and 1223.

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.
