The article examines some questions of formation of productivity of new and localized varieties of barley (Hordeum Vulgare) in the north-eastern zone of the Republic of Belarus. There were investigated 9 varieties. Such indexes as field germination rate, number of grains per head, mass of 1000 grains and biological crop yield are analyzed. The investigation of barley crop yield formation within the structural elements made it possible to draw a conclusion about genetic individuality of malting barley varieties and proved the necessity of application of optimal technology of variety cultivation. The relations between productivity of studied varieties and elements of yield structure, as well as variety response to climatic changes in cultivation conditions are shown.
