Date of creation:

1:20 000 000.Accuracy of the map:
It is created on materials of maps of natural scale 1:5 000 000 - 1:10 000 000 and on literature data.Projection:
"Alber's Equal Area Conic for the USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0.Basic content:
Vector map. Area of distribution is shown by polygon (main distribution) and by dots (sporadic distribution). Zone of weediness is shown by polygon.Accuracy of the classifier:
Within the weed area, the zones of its weediness are shown, established by criteria of occurrence (% of fields where this species is found) and abundance (expressed as projective cover of this species in the field (in % to the field area)) (Tanskii et al., 1998), i.e.; where the occurrence of this species exceeded 50% with its abundance (projective cover) more than 15%.Method of map production:
The areas of distribution and weediness are established according to the analysis of the open published maps and literature. A map compiled by Volkov A.N. (1935) is taken as a prototype, Northeastern border of the area is confirmed by Tolmachev A.I. (1977); its northern border is outlined after Krylov P.N. (1949) and Popov M.G. (1959); southern border of the area is corrected along deserts and semi-deserts; it is shifted northward in the Caucasus after Grossgeim A.A. (1949). The sites of sporadic distribution are depicted according to Tolmachev A.I. (1977) and Kharkevich S.S. (1992). The zone of weediness is not shown, because reference data give values that are below those specified as threshold for the qualifier. Thus, the species occurrence on winter and summer cereals is 1 to 10% in the Perm and Kirov Regions (Korovina, 1982); according to Nikitin V.V. (1983) it meets seldom in crops.Reference citations:
