Autumn Royal
N
Table grape variety.
The geographical origin of the variety is specified or, if this is not possible, the area in which it is traditionally cultivated. The genetic origin of the variety is also indicated whenever it is known from hybridiser data or from genetic analyses published or obtained by the teams at INRAE in Montpellier (UMR AGAP) and Vassal-Montpellier Grapevine Biological Resources Centre (CRB-Vigne).
This table grape variety was obtained at the USDA Station of Fresno in California, in 1981. It would result from the crossbreeding of Autumn Black and C74-1 Fresno.
This information indicates the normal and statutory use for the grapes.

- the tip of the young shoot with a low density of prostrate hairs,
- the shiny bronzed young leaves with no or a very low density of prostrate hairs,
- the shoots with green nodes and internodes,
- the wedge-shaped adult leaves, with five lobes, a very open U- or V-shaped petiole sinus, with sometimes a tooth on the edge, small teeth, long compared to their width at the base with straight sides or with one side concave and one side convex, a weak anthocyanin coloration of veins, an involute, slightly blistered leaf blade, and on the lower side of the leaves, no erect and prostrate hairs,
- the ellipsoid or ovoid 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.
Autumn Royal is rather vigorous and has an erect bearing. It is not very fertile but produces large bunches. It is not very sensitive to millerandage. This variety has a moderate production that can vary from one year to the next. This variety is usually pruned long. The harvest must be performed several times as the maturity and the coloration of berries is heterogeneous and the grapes do not keep well on the vine trunks.
These remarks are also the result of field observations or, if none are available, of bibliography mining and study of bibliographic references.
Autumn Royal is a little sensitive to peduncular rot. It is also very sensitive to downy mildew and rather susceptible to vine leafhoppers.
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)

Autumn Royal’s bunches are large and moderately compact. The berries are seedless, very large, simple-flavored, with a moderately thick skin and a crunchy, sapid pulp. This variety does not recquire an acid gibberellic treatment and has interesting gustatory qualities. The berries are rather sugary for a table grape variety, and if the seeds are present, they are soft and not very noticeable. The bunches have a good cold storage aptitude and resist well to manipulations.
In this section, the list of certified clones is given. Information on clone conservatories is also provided.
The only certified Autumn royal clone carries the number 1220.

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.
