110 R (rupestris x berlandieri)
- A very strong rootstock.
- Since it is a strong rootstock, it delays the ripening of the specie grafted onto it.
- Therefore early species should not be grafted .
- It can resist to active lime up to 17%.
- Suitable for deep profile non-heavy textured soils.
- Although general features are similar with 99R, it resist to aridity better than 99R.
- Growing is strong, it feeds well the specie grafted on it and therefore cultivational applications shouldn't be avoided.
1103 Paulsen (rupestris x berlandieri)
- Has a deep root structure.
- It has a good affinity with grape species.
- It resists to 17% active lime.
- Although it is more suitable for non-heavy textured deep soils, it is suitable for different soil types.
- It is well resistant to saltiness and aridity.
5 BB (riparia x berlandieri)
- Since it has a short vegetation period, it is suitable for Northern regions.
- It is resistant to root tumor nematode.
- Roots are shallow and grow laterally, it isn't good for hot regions.
- It can resist to active lime up to 20%
- It is suitable for heavy textured soils with high water retaining capacities. It should be irrigated for a good growing.
- It delays ripening of the specie grafted on it.
41 B (vinifera x berlandieri)
- Roots grow laterally.
- They enjoy heavy textured soils.
- Resistant to 40% active lime and recommended for extremely limy soils.
- Vegetative period is short.
- Resistant to phylloxera.
- Low resistance to saltiness.
- Provides early yielding for the specie on it.
Rupestris Du Lot (vitis rupestris)
- They aren't so selective for soil types.
- They very enjoy the arid, deep, sandy and low humidity soils and resist to aridity moderately.
- Has a good resistance to phylloxera.
- It resists to 15% active lime.
- Has a good rooting.
- Grafting success and affinity is good with domestic grape species.
- A strong rootstock.
- Vegetation period is long.
- Sensitive to leaf phylloxera.
99R: (Rupestris x Berlandieri)
- A strong rootstock.
- Roots are resistant to phylloxera but sensitive to leaf phylloxera.
- Although it resists up to 17% active lime but don't resist to salt.
- Well resistant to nematodes.
- It forms canes well lignifying and rooting.
- Since it vertically grows and roots go deeper, this rootstock is suitable for inclined and arid areas.
- Since it delays ripening of the specie on it, it isn't recommended for northern sides.
