Latin name for offspring or offspring, which the Russian researcher Dr. Alexander Mikhailovic Negrul (1900-1971) as a name for his Grape varieties classification used. There were always attempts, due to the geographical ancestry who use destem- and table grapes ) or the outer features to find a grouping. Also Negrul dealt with it and finally created from 1946 to 1958 on the basis of investigations of Russian varieties three ecologically geographic groups he called Proles. This classification is based inter alia on the distinction of the hair of the Leaf undersides during the sprouting, However, this system is not based on a botanical but on a geographical basis.
The first group Proles pontica covers the area from the Balkans through Asia Minor and the Black Sea region to the western Caucasus Bessarabia (these are today's Moldova as well as parts of Ukraine ) Georgia. Greece, Asia Minor (Anmatolia, part of the Turkey ) Romania and Hungary, These are, for example, the varieties Clairette. Furmint. Hárslevelü and korinthiaki, The second group Proles orientalis comprises varieties east of the Caucasus Afghanistan. Iran and the Middle East (Subproles Caspica) and a group of Mediterranean-wide table grapes, mainly bred and distributed by the Arabs (Subproles antiasiatica). For the most part it is table grapes such as the two varieties Muscat d'Alexandrie and Sultana but also the wine grape Cinsault, The third group Proles occidentalis includes Central Europe, Italy. France and Spain, These include, for example, the three varieties Cabernet Sauvignon. Chardonnay and Riesling,
This grouping in regional leading varieties however, with certain common group characteristics can not satisfy because too many varieties do not fit into this scheme. Although Negrul's classification scheme may apply to a core of selected regional varieties, over the millennia too many varieties have been moved to new growing areas where they have spread and continued to cross. A typical example of this is probably the variety associated with the Pontic Proles Gouais blanc or White Heunisch, which has crossed over several centuries with numerous European common varieties, so that over 100 resulting varieties such as Blaufränkisch. Chardonnay or Riesling including their descendants are hardly to be classified in a regional differentiation scheme. Therefore, this typing in Proles is hardly considered today. The French ampelographer Pierre Galet (* 1921) proposed in 1988 a continuation of this classification, which disregards geographical considerations and is based only on three types of hair (wool hair, fitting, cobweb).
