Date of creation:

Scale:

1:20,000,000

Accuracy of map:

Map was created using a map of the gardens of the former USSR with the scale of 1: 20,000,000.

The projection:

"Alber's Equal Area Conic for Russia", 9, 1001, 7, 100, 0, 44, 68, 0, 0.

Basic contents:

Map is a vector file consisting of polygons and points. Points represent recorded locations of the species; polygons represent area of possible distribution of the species.

Accuracy of classifier:

Polygons are based on literature sources, political boundaries and ecological descriptions. Point data were obtained from literature sources and herbarium specimens. Polygons are based on literature sources, herbarium samples, and field surveys by the authors.

Method of map production:

GIS specialists at the Moscow Soil Institute carried out the mapping. Working with agronomists, historical agricultural statistics were reviewed at the district (rajon) level to determine whether or not the crop was cultivated. Crop distribution was based on crop production at the rajon-level, which was further refined using the boundaries shown on the 1:4000000 map of arable lands (Koroljeva et al., 2003). The area map was created using Tulupnikov (1960) and State list (1994, 2004). The polygon area covers Middle Asia, Transcaucasica, the Northern Caucasus, Southern Ukraine, the Lower Volga and Moldova, according to the following sources: Tulupnikov (1960), Shorin (1973), 1976, 1986), Vehov (1978), Golubeva (1983), Shepel' (1989), and Davletshin (1999). Also, Vasilevskij (1990) and Bobrenko (1997) reference the successful cultivation of the species in Western Siberia and well as in Kaliningrad, Briansk, Tatarstan, Bashkiria, Krasnojarsk, Novosibirsk and the Far East; these areas are represented by points. Also instrumental in map development was a consultation with the General Specialist in the Grain Cultures Department of VIR, B.N. Malinovskij, PhD.
