Abstract
Using the methods of artifi cial freezing and multidimensional statistical analysis, the total winter hardiness potential of more than 50 varieties and forms of apple trees has been revealed. The ranking of the genotypes according to the general degree of winter hardiness, taking into account its main components and the physiological disparity of the damaged tissues, was carried out. It was based on the proximity of the object to the model of the ideal variety.

Summary
Ключевые слова: яблоня, сорта, селекция, морозостойкость, компоненты зимостойкости. Summary. В настоящее время в селекционной практике при оценке зимостойкости сортов и гибридного материала широко и успешно используется метод прямого лабораторного промораживания, предложенный М. Отдельно оцениваются повреждения каждой ткани и почек для всех компонентов зимостойкости.
