TS 4076

TS 4076 is a terminology standard for grape vine rootstocks, providing definitions that support a common technical language for the root system material used in viticulture. Its focus is the naming of rootstock groups resistant to phylloxera and nematodes, so that these commonly used rootstocks are understood consistently in practice.

The rootstock concept and why it matters

A grapevine rootstock is the rooted part onto which the fruiting variety is grafted; in practice it is selected less for fruit character and more for adaptation to soil conditions, pests and the growing environment. Resistance to phylloxera and nematodes is one of the main reasons rootstocks are used in vineyards. The terminology covered by this standard brings clarity to names such as pure American, Americo x American and Franco x American rootstocks, while also covering the principal resistant rootstocks used in Turkey.

Definition groups covered

• Phylloxera-resistant grapevine rootstocks
• Pure American rootstocks
• Americo x American rootstocks
• Franco x American rootstocks
• Nematode-resistant grapevine rootstocks
• Definitions for the principal rootstocks used in Turkey

From a general technical perspective, a terminology standard like this helps keep cultivar and rootstock names consistent across nursery production, vineyard establishment, research, trade and technical documentation. TS 4076 is about clarifying the shared vocabulary for resistant rootstocks rather than prescribing a cultivation method.
