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:
The vector map is composed of 4 thematic layers, where area and severity zones are shown by polygons.Accuracy of the classifier:
The area of distribution is divided into three zones of severity according with Yu.I. Vlasov et al. (1973). In the zone of high severity, the disease development on solanaceous cultures is more than 50%, and epiphytoties are frequent; in the zone of moderate severity, the Cucumber Mosaic Virus epiphytoties appear every 6th or 7th year; in the zone of low severity the disease development is 10% and less.Procedure of the map drawing:
Zones of severity are drawn on a blank map based on published references. The zone of high severity includes Republics of Central Asia, Lower Volga region, the Northern Caucasus and Transcaucasia (Vlasov et al., 1972; Parshin, 1974; Glushak, 1969; Tsyplenkov et al., 1992; Samsonova et al., 2001). The zone of moderate severity includes Byelorussia, Moldova, Baltic States, also some regions of Ukraine, and Khabarovsk Territory in the Far East of Russia (Ignash, 1977; Ges., 1968; Stanyulis et al., 1977; Dashkeeva et al., 1968). Low severity of the CMV is characteristic of all the rest part of the tomato cultivation zone (Tsyplenkov, 1986). Correction of the severity zones has been carried out according to the Terekhina.s vector map of potato distribution (Terekhina, 2004)Reference citations:
