Genetic origin The genetic origin of the variety is also indicated when known thanks to hybridiser data or genetic analysis either published or obtained by the teams at INRAE in Montpellier (UMR AGAP) and at the Vassal-Montpellier Grapevine Biological Resources Centre (CRB-Vigne).

The genetic origin of the variety is also indicated when known thanks to hybridiser data or genetic analysis either published or obtained by the teams at INRAE in Montpellier (UMR AGAP) and at the Vassal-Montpellier Grapevine Biological Resources Centre (CRB-Vigne).

This variety results from the crossbreeding of 1203 Couderc (Vitis vinifera - Vitis rupestris) and Vitis riparia cv. Gloire de Montpellier.

Evolution of mother vine surfaces The figures indicated are taken from the successive annual reports drawn up with data from: IVCC, ONIVIT, ONIVINS, VINIFLHOR and FAM.

Descriptive elements

Only the main ampelographic elements enabling the rootstocks to be characterised and identified are provided. They are described according to the ampelographic 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 buds, flowers and adult leaves were taken indoors by the INRAE team at Domaine de Vassal from material sampled from the ampelographic collections of the Vassal-Montpellier Grapevine Biological Resources Centre.<br><br>
Note: the scale of the photos is not the same for the three organs shown. The photos of buds have been reduced (x 0.5 approx.), as have those of the adult leaves (x 0.25 approx.), while those of the flowers have been enlarged (x 4 approx.).

The identification is based on:
- the tip of the young shoot that is half open, with no or a very low density of prostrate hairs,
- the shoots with a smooth surface and a moderate to strong anthocyanin coloration,
- the circular, involute, funnel-shaped adult leaves, with a slightly open or closed petiole sinus, an undulate leaf blade between the veins, large teeth with straight sides,
- the male flowers,
- the browny red or purplish woody shoots with no erect and prostrate hairs.

Resistance to soil parasites The degree of tolerance to the root form of phylloxera and resistance to nematodes (Meloidogyne hapla, Meloidogyne incognita and Meloidogyne arenaria), to Agrobacterium vitis (the bacterium responsible for burls) and to certain soil fungi is stated on the basis of observations or bibliographical data.

The degree of tolerance to the root form of phylloxera and resistance to nematodes (<I>Meloidogyne hapla</I>, <I>Meloidogyne incognita</I> and <I>Meloidogyne arenaria</I>), to <I>Agrobacterium vitis</I> (the bacterium responsible for burls) and to certain soil fungi is stated on the basis of observations or bibliographical data.

196-17 Cl is moderately tolerant to the root form of phylloxera and it is best to plant it under unfavorable conditions for this pest. It is aldo sensitive to Meloidogyne arenaria and Meloidogyne incognita nematodes.

Adaptation to the environment $This paragraph provides information on the behaviour of the rootstock variety in relation to the structure, texture and composition of the soil, its mineral content and the soil’s pH. It also states the behaviour of the rootstock when faced with an excess or lack of water during the vegetative period. Chlorosis Iron chlorosis is related to problems of iron assimilation due to low iron content and/or high carbonate content in soil. Total calcium carbonate content alone gives only a partial idea of the chlorosis-inducing power of the soil. The active calcium carbonate content corresponds to the percentage of carbonate present in the fine fraction of the soil (clays, fine silts). Depending on the characteristics of the parent rock and its geological origin, this represents a variable percentage of the total calcium carbonate. The chlorotic power index (IPC) is a calculation which takes into account the active calcium carbonate content and the easily extractible iron content of the soil. These three values provide an insight into the risk of chlorosis and allow growers to choose the most suitable rootstock variety accordingly. Tylosis and apoplexy These apoplexy phenomena are linked to problems of water circulation through the plant when evapotranspiration is high (dry wind following heavy rainfall in the summer season) and the absorption of water through the roots is limited. In this case, the high pressure in the vessels causes air bubbles (cavitation) and tyloses (invagination of the membrane of neighbouring cells in the vessels) to form, which causes a slowing of sap circulation and water stress in the leaves.$

196-17 Cl is sensitive to chlorosis and only resists up to 6% of "active" limestone and to an IPC of 5. It is well adapted to drought and acidic soils. 196-17 Cl is particularly suited to schist or granitic, dry, poor, superficial and stony soils along to sandy soils if there is no endoparasitic nematodes. This rootstock is also slightly tolerant to chlorides.

Interaction with grafts and production objectives The rootstock may interact with the characteristics of the graft in terms of precocity of the vegetative cycle and the growth and development of the branches, as well as yield factors (fertility and berry size). In some cases, the risks of incompatibility or poor affinity of the rootstock variety with a graft variety are specified.

196-17 Cl gives a significant vigor to the graft and can be used to replace missing plants.

Vegetative propagation aptitudes The level of wood production by the rootstock strains is stated (source: ENTAV-ONIVINS survey of grapevine nurseries, April 2001). The suitability for cleaning, disbudding, cutting and grafting is also specified. Further details are provided if the rootstock variety requires special precautions during grafting and layering.

196-17 Cl has a moderate wood production (30 000 to 60 000 m/ha) but has good cutting and grafting capacities.

Resistance to aerial parasites Susceptibility to the gall form of phylloxera is also specified, as is the level of resistance to or tolerance of the following diseases: downy mildew (Plasmopara viticola), anthracnose (Elsinoe ampelina) and bud mite disease (Colomerus vitis) on the basis of observation or bibliographical data.

196-17 Cl is tolerant the gall form phylloxera is good and it is moderately resistant to downy mildew.

Clonal selection in France All certified clones are listed, as are the surface areas of the mother vine of clones that are propagated. For the moment, clonal selection of rootstock is conducted solely for sanitary purposes.
