' Kober 125 AA' is a rootstock for the biotechnological control of the root phylloxera in grape varieties susceptible to phylloxera. It belongs to the group of Vitis berlandieri x Vitis riparia hybrids and has very similar properties to the rootstock ' Kober 5 BB '.
ancestry
Cross of Vitis berlandieri PLANCHON x Vitis riparia MICHAUX, selection Sigmund Teleki, selection Franz Kober, 1896, Austria.

- Full-grown leaves: large, undivided, upper side dark green with a somewhat elongated central lobe, underneath rough and bristly, leaf veins on the underside and petiole with hairy hairs, petiole U-shaped, leaves are highly susceptible to aphid
- Shoots: very bristly hairy
- Tendrils: predominantly three-part
- Flower: female pseudo-hermaphrodite
- Grape: small with small, round, black-blue berries
Properties - use
The phylloxera resistance against the root phylloxera is good. It has a very good graft affinity and excellent rooting ability. The growth is medium to strong like 'Kober 5 BB'. It is therefore only suitable for educational systems with large standing spaces. Has good drought resistance. If the cane load is too high, there is a delay in maturation.
The root system has a good ability to acquire nutrients and is well suited as a base for the varieties from the Burgundy family. It is unsuitable for shallow and compacted soils. The chlorosis resistance is good ( activated lime tolerance ~ 17%, ~ 40% total lime). The rootstock is less suitable for flower-sensitive varieties. She is very sensitive to magnesium deficiency .
Clones
The clones 125AA N501 and 125AA N502 come from seedling families of the cross Vitis berlandieri × Vitis riparia , which were initially selected by Sigmund Teleki in Villány / Hungary and later processed by Franz Kober in Klosterneuburg / Austria. The seedlings were in Rhodt / Pfalz and later in Neustadt / Wstr. and cheap home / Palatinate planted and checked. The clones were registered with the Bundessortenamt on 2006. The maintenance breeder is the state of Rhineland-Palatinate, represented by the DLR Rheinhessen-Nahe-Hunsrück.
