The famous rootstock vine is an interspecific new variety between American wild vines of the species Vitis berlandieri x Vitis riparia; it is an all-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, Selektsii Kobera, Teleki 5 BB and Teleki Kober 5 BB. It is one of the first phylloxera-resistant rootstocks to achieve worldwide significance and is still used today in many countries in the form of various clones. Its history shows how time-consuming and complex the breeding of new vines is and how carefully and precisely it has to be done. All breeding processes must be meticulously documented.
The glossary is a monumental achievement and one of the most important contributions to wine knowledge. Of all the encyclopaedias I use on the subject of wine, it is by far the most important. That was the case ten years ago and it hasn't changed since.
