Suffolk red
Rs
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 has been obtained in 1935 at the Geneva Station, in New York State. This interspecific hybrid’s pedigree involves Vitis labrusca and Vitis vinifera.
This information indicates the normal and statutory use for the grapes.

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 green tip of the young shoot with a medium to high density of prostrate hairs,
- the green yellow young leaves with a low to medium density of prostrate hairs,
- the shoots with green internodes,
- the circular, entire adult leaves, with a closed V-shaped petiole sinus with overlapping lobes, mucronate teeth, short compared to their width at the base with straight or concave sides, no anthocyanin coloration of veins, a twisted or revolute, finely blistered leaf blade, undulate between the veins, and on the lower side of the leaves, no or a very low density of erect and prostrate hairs,
- the obloid or round-shaped berries, with a pink skin at maturity.
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.
Suffolk red has a semi-erect to erect bearing. This variety has a vigorous vegetation that recquires regular tipping and topping. As its productive potential is low, this variety must be pruned long. Suffolk red strongly expresses magnesium deficiency. It is sensitive to drought, millerandage and winter frosts. This variety can sometimes have berry shrivelling problems at maturity.
These remarks are also the result of field observations or, if none are available, of bibliography mining and study of bibliographic references.
Suffolk red is sensitive to rot, downy mildew and especially to vine leafhoppers.
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.
Suffolk red’s bunches are small and loose. The berries are seedless, small, with a slightly foxy flavor, a thin skin and a juicy pulp. At maturity, the berries are a little acidic and rather sugary. During the storage, Suffolk red can be sensitive to berry shedding.
In this section, the list of certified clones is given. Information on clone conservatories is also provided.
There is no certified clone for this variety yet.
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: 5 days after Chasselas.
Grape maturity: early-season, same as Chasselas.
