ABSTRACT
Results of long-term studying of varieties of spring barley (Hordeum vulgare L.) in competitive field varietal test of the North-East Agricultural Research Institute and on State variety test stations of the Kirov region are presented in the article. Varietal specificity in their reactions to change of soil-environmental conditions is revealed. A share of influence of environmental conditions on formation of productivity and effect of “genotype – environment” interaction in a studied set of varieties is established. Ranging of barley varieties on productivity in favorable and stressful conditions of growth is presented; the variation of productivity on years is defined. The various methods based on an estimation of productivity of
varieties in years differing on meteorological conditions and sites of study were used for obtaining the varieties characterized by high ecological stability. The botanical and economic-biological characteristic of new highyielding varieties of barley different by high ecological stability is given. The obtained data allows to recommend a set of new ecologically stable barley varieties adapted for conditions of cultivation for wider using in agricultural industry.
