1:20 000 000.Accuracy of map:
It is created on information taken from the map of scale 1:33 000 000.Projection:
"Alber's Equal Area Conic for the USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0.Basic contents:
Vector map is composed of 4 thematic layers. Zones of distribution and severity are shown by polygons.Accuracy of the classifier:
According to the method of Vlasov & Larina (1982), three zones of PLRV severity are established in the area of distribution. In the zone of high severity, the distribution of this disease on potato is higher than 40-50%, and frequent epiphytoties occur. In the zone of moderate severity, the epiphytoties occur every 8-10 years; in the zone of low severity, the disease development does not exceed 10%.Method of map production:
The area and severity zones have been marked on a blank map by results of the analysis of published materials. The zone of high severity includes the republics of Central Asia, Transcaucasia, Kazakhstan, the Northern Caucasus, western regions of Ukraine. The zone of moderate severity is shown for Byelorussia, Central Chernozem zone, Moldova, Primorskii Territory, Baltic States, Sakhalin, Altai Territory, Nizhnii Novgorod, Ivanovo, and Velikii Novgorod Regions. The potato leaf roll does not exceed 5-10% on the remaining territory of potato growing (Bubentsov, 1967; Ambrosov, Davidchik, 1975; Randalu, Kass, 1976; Zykin, 1976; Zhukova, 1983). Correction of severity zones has been performed according to the vector map of the largest potato lands distribution (Koroleva et al., 2003).Reference citations:
