The article describes the results of a comparative study in a two-year cycle of observation of the content of microelements in fruits of the natural wild form of Cornus mas. L. and its 5 varieties of Ukrainian breeding (Vladimirsky, Vydubetsky, Eugenia, Lukianovsky, Radost) introduced in the conditions of Belarus. Distinct genotypic differences in the parameters of their accumulation, which depend to a great extent on weather conditions during the vegetation period, are identified. It's shown that the highest content of nitrogen in fruits is observed in Vydubetsky and Radost varieties, that of phosphorus - in Radost, that of potassium - in Vladimirsky and Lukianovsky, that of calcium - in Eugenia, while there is no distinct genotypic differences in magnesium content. Most of the introduced varieties of cornelian cherry, especially in the first year of study, exceeded its natural form in the content of nitrogen and phosphorus in their fruits, while potassium and calcium content showed an ambiguous direction of differences. As far as magnesium content is concerned, there were no differences observed. At the same time weather conditions of the vegetation period not only determined to a great extent the parameters of microelements accumulation in Cornus mas. L. fruits, but had a considerable impact on the extent and direction of differences in their content in variety forms and in the natural form.
