Latin name for offspring or offspring, which the Russian researcher Dr. Alexander Mikhailovic Negrul (1900-1971) as the name for his Grape varieties classification used. There were always attempts due to the geographical origin, the use ( destem- and table grapes ) or the external characteristics to find a grouping. Negrul also dealt with this and finally created three from 1946 to 1958 based on studies on Russian varieties ecologically geographical groups, which he called Proles. This classification is based, among other things, on the differentiation of the hairiness of the Leaf undersides during the sprouting, This system is not based on a botanical basis, but on a geographical basis.

The first group Proles pontica covers the area from the Balkans to Asia Minor and the Black Sea region to the western Caucasus Bessarabia (these are today's Moldova as well as parts of the Ukraine ) Georgia. Greece, Asia Minor (Anmatolia, part of the Turkey ) Romania and Hungary, For example, these are the varieties Clairette. Furmint. Hárslevelü and korinthiaki, The second group Proles orientalis includes varieties east of the Caucasus Afghanistan. Iran and the Middle East (Subproles Caspica) and a group of Mediterranean spread table grapes, which were mainly grown and spread by the Arabs (Subproles antiasiatica). For the most part 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 into regional ones leading varieties with certain common group characteristics, however, cannot satisfy, because too many varieties do not fit into this scheme. Even though Negrul's classification scheme may apply to a core of selected regional varieties, too many varieties have been brought into new cultivation areas over the millennia, where they have spread and crossed. A typical example of this is the variety that probably belongs to the Pontic Proles Gouais Blanc or Weißer Heunisch, which has crossed over several centuries with numerous common European varieties, so that the more than 100 resulting varieties such as Blaufränkisch. Chardonnay or Riesling including their descendants can hardly be classified in a regional differentiation scheme. That is why this typing is hardly taken into account in Proles today. The French ampelographer Pierre Galet (1921-2019) proposed a continuation of this classification in 1988, which does not take geographical aspects into account and is based on only three types of hair (woolly hair, close-fitting, cobweb).
