A comprehensive assessment of the sustainability of nuts of the genus Juglans on adaptive features in the Voronezh region

Taking into account the high value of nuts of the genus Juglans, the increase in their production should go not only through the selection and breeding of the best varieties and forms, but also by shifting the existing border of cultivation to the north, into "new" regions, where nut-bearing crops are not yet widespread. For full adaptation, all components of plant resistance should be at a high level. In this regard, the main purpose of the work is to study and analyze the adaptive features of plants. Were studied local forms of the walnut, nut the manchurian, nut the black, nut the gray and nut the heartshaped. In determining the resistance of plants according on the main adaptive attributes, generally accepted methods based on artificial modeling of unfavorable conditions were used. An integrated approach to the determination of the stability of forms and species of nuts is proposed, which consists of an integrated assessment of the main components of plants, which has an advantage over the conventional field method of evaluation, since a reliable determination of stability in the field requires a long observation (sometimes several years). On the basis of indicators of comprehensive of the sustainability, a scale for the optimal use of forms and species of nuts of the genus Juglans in the Voronezh region was compiled.
