Planning and effective implementation of the productive and adaptive potential of agricultural plant varieties is possible only if their agroecological characteristics are taken into account. Agroecotypes are formed under the influence of artificial and natural selection in man- made artificial agrosystems. Ecotypes of wild plants capable of self-reproduction are formed under the influence of natural selection only under a relatively constant set of external conditions. On the territory of the Russian Federation, for the geographical classification of agroecotypes, one should be guided by the «Natural and agricultural zoning of the land fund of the Russian Federation» (1983), for the edaphic classification - by the «Federal Register of Plant Production Technologies» (2000). Two or more different ecotypes of the same species cannot grow in the same place. In the state zoning of agricultural plant varieties, when the main criterion for admission is yield, very often varieties of different agroecotypes are cultivated in the same territory.
