7 Results for colombard

Variety: Colombard
Legal information: In France, Colombard is officially listed in the "Catalogue of vine varieties" on the A list and classified. This variety is also listed in the catalogues of other Member States of the European Union: Bulgaria, Cyprus, Portugal and Spain.
Suitability: Colombard is a fertile, very vigorous and productive variety. It can be pruned long or short, depending on production objectives. Pruning is fairly difficult because Colombard wood is hard. At maturity, this variety has a tendancy to berry shedding.
Potential: The bunches and berries are medium in size. This variety produces pleasant, aromatic wines with a good acidity. Spirits obtained from Colombard are of avergae quality and are mostly blended.
Clones: The fourteen certified Colombard clones carry the numbers 551, 552, 553, 605, 606, 607, 608, 609, 625, 626, 695, 938, 1179 and 1180. More than 180 clones are gathered in two conservatories planted in 1995 and in 2002 in the French department of Gers. An other conservatory of almost 200 clones was planted in 2010 in the French department of Charente.

Variety: Berlandieri - Colombard 2

Interaction: 101-14 MGt usually has a very good affinity with the grafts. The first growth of plants is fast but the vigor confered is nevertheless limited. Thus, this rootstock contributes to manage the plant growth and has an influence on the earliness of the vegetative cycle. 101-14 MGt induces moderate yields with an often a lower average berry weight compared to those obtained with other rootstocks. The varieties grafted onto 101-14 MGt generate balanced, quality products with good maturity and the associations with Cabernet franc, Cabernet-Sauvignon, Chardonnay, Chenin, Colombard, Gamay, Grenache, Petit Verdot, Sauvignon, Semillon and Syrah are appreciated.

Interaction: The growth and fruiting speed given by 161-49 C is quite slow. In addition, the limited yields during the first years reduces the risks of tylosis. This rootstock confers a moderate vigor and balances the vegetative growth. The varieties grafted onto 161-49 C produce quality fruits and the blends made with Chardonnay, Colombard, Merlot, Pinot and Ugni blanc are particularly appreciated. It also shows good results with hybrid grapes. However, some joining problems have sometimes been reported, particularly with Carignan, Gamay and Servant.

Interaction: 3309 C generally has a good affinity with grafts. However, some joining problems have been noticed with Cabernet-Sauvignon, Chenin, Dattier de Beyrouth, Pineau d’Aunis, Riesling, Syrah and Sauvignon. Some of these varieties are grafted in significant amount with 3309 C. The growth and fruit set speed given by 3309 C is a little slow. Vigor confered by 3309 C is low to moderate and vegetative growth is balanced, especially if the agronomic fertility of the soil is not too high. 3309 C promotes the fruit set of sensitive varieties to coulure. The varieties grafted onto this rootstock produce recognized quality products and the associations with Cabernet franc, Cabernet-Sauvignon, Chardonnay, Colombard, Fer, Gamay, Gros Manseng, Melon, Merlot, Petit Manseng, Pinot, Sauvignon, Semillon, Riesling, Syrah and Tannat are particular appreciated.

Origin: Based on genetic analyses carried out in Montpellier, this variety results from the crossbreeding of Berlandieri Colombard number 1 B (from a crossbreeding between Vitis berlandieri and Vitis vinifera cv. Ugni blanc) and 31 Richter (from the crossbreeding between Vitis berlandieri cv. Rességuier number 2 and Vitis longii cv. Novo-mexicana).

Interaction: Generally speaking, 5 BB confers a very high vigor to the grafts and tends to delay the maturity. It is sometimes incompatible with some varieties (for example: Cabernet franc, Cabernet-Sauvignon, Colombard, Sauvignon) particularly when they carry the grapevine leafroll-associated virus 2 (GLRaV-2). In the event of a grapevine fanleaf virus infection, 5 BB clearly shows the presence of endocellular cords in the wood vessels. In terms of production, this rootstock, which is sometimes used to replace missing plants, tends to favor alternating phenonema and irregular results depending on the year. 5 BB sometimes induces the production of fruits with low sugar and polyphenol contents.
