Abstract

The genotypical potential of strawberry varieties is the basis for the implementation of economically valuable crop indicators in specific growing conditions. Assessment of the variability of productivity traits and quality of berries is one of the key directions in many modern studies on the selection and variety study of garden strawberries. The goal of this work was to assess strawberry varieties by a complex of characteristics of the yield structure and fruit quality, taking into account their genotypic characteristics, as well as to identify of their hereditary potential in regional cultivation conditions. The analysis of long-term data on 17 varieties of strawberries has been carried out. Using the methods of two-way analysis of variance, contributions of the principal components and Ward’s cluster analysis, an assessment was made of the variability of the taken into account traits in strawberry varieties. Combining the studied varieties into groups made it possible to identify the best forms by the valuable traits. A high responsiveness to the cultivation conditions in the Krasnodar region was established for the varieties Nelli, Alba, Florence, Elegia, Honeoye, Onda and Vima Xima in accordance with their genotypic potential.
