Ampelographic description
The identification is based on:
- the tip of the young shoot that is half-open or closed with a piping anthocyanin coloration and a medium density of prostate hairs,
- the slightly bronzed young leaves,
- the shoots with a ribbed surface, a circular or slightly elliptic section and a high density of erect hairs on the nodes and the internodes,
- the large, wedge-shaped, revolute adult leaves, with a slightly open V-shaped petiole sinus, a folded leaf blade near the petiole sinus, short teeth compared to their width at the base, green veins, and on the lower side of the leaves, a low to medium density of erect hairs,
- the male flowers,
- the woody shoots with a high density of erect hairs on the nodes and the internodes.

Resistance to soil parasites
8 B is highly tolerant to the root form of phylloxera. It is also very resistant to Meloidogyne arenaria and Meloidogyne incognita nematodes.
Adapt to environment
8 B resists up to 17% "active" limestone. Its resistance to iron chlorosis is thus considered moderate and its resistance to drought is good.
Interaction with grafts and production objectives
8 B confers a moderate vigor to the grafts and induces medium yields.
Aptitudes for plant propagation
8 B wood production is good (50 000 to 70 000 m/ha). This rootstock has a moderate cutting capacity and a good grafting aptitude.
Resistance to aerial parasites
8 B is not very or moderately sensitive to the gall form of phylloxera and is highly resistant to downy mildew.
