Negrul Alexander

The Soviet biologist and botanist Dr Alexander Mikhailovič Negrul (1900-1971) was one of the most important ampelographers of the 20th century. He probably came from the Bessarabia region (now Moldova) and worked for many years at the renowned Magarach Institute of Viticulture and Oenology on the Crimean peninsula. He also worked there as grower and created the new Pervomaisky and Pobeda varieties, among others.

Negrul worked intensively on the systematics, evolution and geographical distribution of the cultivated European vine Vitis vinifera. His most important achievement was the introduction of a vine systematics, which he called Proles (progeny). On the basis of morphological, genetic and geographical characteristics, he distinguished the three main groups Proles orientalis (eastern vines), Proles pontica (vines of the Black Sea region) and Proles occidentalis (western vines). This categorisation was a milestone in international vine classification. However, this system is rarely used today, as it proved to be too schematic and imprecise in some cases.
