Kober 5 BB

The famous rootstock is an interspecific new breed between American Wild vines of the species Vitis berlandieri x Vitis riparia; it is pure female variety, Synonyms are 5 BB, 5 BB Selection Kober, Berlandieri x Riparia Kober 5 BB, C-25, Craciunel 25, Kober, Kobera 5 BB, Kobravka, Selektivii Kobera, Teleki 5 BB and Teleki Kober 5 BB. It is one of the first phylloxera-resistant Documents that have gained worldwide importance and that are still available today in countless countries in the form of various Clones is used. The history of this vine is a vivid example of how lengthy and time-consuming it is new breed of vines and how carefully and exactly you have to proceed. All breeding operations must be meticulously documented.

Kober 5 BB - Documentary garden by Franz Kober 1930 and grapes

The Hungarian winery owner Zsigmond Teleki (1854-1910) was with its underlay graves used for example Solonis not satisfied and had learned about relevant literature that the wild vine Vitis berlandieri and their hybrids are ideal for limestone soils. He obtained 22 pounds of seeds from the nursery operator Euryale Rességuier. Seeds because the traffic with vine parts because of the peak phylloxera disaster was severely restricted, at least between individual states. Teleki planted on the vineyards of his company in Villány around 40,000 seedlings, He was believed to have only received pure Vitis berlandieri, but it turned out that only 10 Berlandieri seedlings and the majority hybrids out intersections between Vitis berlandieri x Vitis riparia, Vitis berlandieri x Vitis rupestris and others were.

The Berlandieri-Riparia hybrids selected by Sigmund Teleki later provided the basis for the documents Kober 125 AA, Kober 5 BB, Teleki 5 A (according to the descendant Andor Teleki identical to Kober 5 BB), Teleki 5 C, Teleki 8 B and SO 4 (selection Oppenheim 4). Franz, a friend of Teleki Kober (1864-1943) commissioned him in 1904 to give him every distinctive type of Berlandieri x Riparia shoots to be sent to Austria (at that time the Habsburg Empire). Kober planted this cuttings in a property leased from the Ministry of Agriculture on Nußberg near Wien (Austria). Kober made a selection beforehand. He had selected 50 types in four groups, which he named A, B, C and D. The group assignment took place after morphological Aspects (shape and appearance).

From around 100 plants, Kober selected particularly robust and vigorous, which he identified with a double letter. This is how the Kober 5 BB got its name, because the 5th floor of the BB group ultimately turned out to be the best for the Austrian location. Kober now left this (only) vine in the nursery in Wiener Neustadt increase vegegatively, In 1920, he went public 16 years after the project started. That was relatively quick, because it often takes several decades for a new one vine or document is permitted.

Kober had concealed the origin of Teleki and called it "Kober vine". The basic (and also very important) basic selection had already been made by Sigmund Teleki. Both breeders made the mistake of marketing very similar types with the same number designation. A number of selections were carried out from this mixture in the individual wine-growing countries. The director of the viticulture school Krems (Lower Austria) Ferdinand Reckendorfer selected the documents R (eckendorfer) 7, R 27, R 43 and 8-35 from the Kober 5 BB. And the German biologist Dr. Carl Börner (1880-1953) selected 59 B (örner), 65 B and 68 B. However, none of these selections became important. The Austrian winegrower Josef especially advocated a wide use of the base Mader (1876-1938) a.

Resistance to the root lice of the phylloxera is good. Although it is susceptible to leaf vine, this does not play a role as an underlay (but it does do so in the propagation). It is well tolerated by limestone soils and dryness. The half-deeply rooted vine is vigorous, which also affects the top. It is resistant to chlorosis, but less good for Verrieseln trending varieties. Today, various clones of Kober 5 BB are marketed after a phytosanitary check (phytosanitary certificate). The pad is used in Germany and Austria, as well as in many other countries.
