The famous rootstock is an interspecific new breed between American Wild vines of the species Vitis berlandieri x Vitis riparia; it is a pure one female species, Synonyms are 5 BB, 5 BB Selection Kober, Berlandieri x Riparia Kober 5 BB, C-25, Craciunel 25, Kober, Kobera 5 BB, Kobravka, Selektsii Kobera, Teleki 5 BB and Teleki Kober 5 BB. It is one of the first phylloxera-resistant Documentation that has gained global importance and that still today in countless countries in the form of various Clones is used. The career of this vine is a vivid example of how tedious and time-consuming the new breed of vines is and how carefully and exactly you must proceed. All breeding operations must be meticulously documented.
The Hungarian estate owner Sigmund Teleki (1854-1910) was with his used dummies such as for example Solonis not satisfied and had learned about relevant literature that the wild vine Vitis berlandieri and their hybrids Excellent for lime soils are suitable. He received 22 pounds of semen from the vineyard operator Euryale Rességuier. Seeds because the traffic with vine due to the peak phylloxera disaster was severely limited at least between individual states. Teleki planted on the vineyards of his farm in Villány around 40,000 seedlings, He was believed to have received only pure Vitis berlandieri, but it turned out that only 10 Berlandieri seedlings and the largest part 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 offspring Andor Teleki identical to Kober 5 BB), Teleki 5 C, Teleki 8 B and SO 4 (Selection Oppenheim 4) dar. The friend of Teleki Franz Kober (1864-1943) instructed him in 1904 to give him of every distinct type Berlandieri x Riparia shoots to Austria (then the Habsburg Empire) to send. Kober planted these cuttings in a property leased by the Ministry of Agriculture on Nußberg near Wien (Austria). Kober made a selection before that. 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 selected Kober particularly robust and vigorous, which he marked with a double letter. So the Kober 5 BB got its name, because the 5th floor of the group BB turned out to be the best for the Austrian location conditions. This (only) Rebstock let Kober now in the nursery in Wiener Neustadt multiply vagivatively, In 1920 he entered the public 16 years after the beginning of the project. That was relatively quick, because it often takes several decades to a new one vine or underlay is allowed.
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. In the individual wine-growing countries a number of selections were made from this mixture. The director of the viticulture school Krems (Lower Austria) Ferdinand Reckendorfer selected from the Kober 5 BB the documents R (eckendorfer) 7, R 27, R 43 and 8-35. And the German biologist Dr. Carl Börner (1880-1953) selected 59 B (örner), 65 B, and 68 B. All these selections, however, gained no significance. For a broad use of the base sat especially the Austrian wine-growing engineer Josef Mader (1876-1938).
Resistance to the root lice of the phylloxera is good. Although it is susceptible to Blattreblaus, which plays as a rootstock not matter (but very well in the propagation). It has good compatibility with calcareous soils and drought. The semi-deep rooted vine is vigorous, which also affects the top. She is resistant to chlorosis but less good for Verrieseln Tending varieties. Today, various clones of Kober 5 BB are marketed after a phytosanitary control (Plant Health Certificate). The underlay is used in Germany and Austria, as well as in many other countries.
