Abstract
Studies carried out in the laboratory of physiology of the VNIISPK resistance. Material the 21 of apple varieties breeding VNIISPK. Frost hardiness study in the middle of winter in the artificially modeled conditions allowed estimating the potential of apple variety resistance to winter frosts and revealing varietal differences in buds and basic tissues of shoots according to their winter hardiness. The modeling of winter frost -38°C showed that the majority of studied apple varieties were able to develop maximum frost hardiness of buds and tissues. Antonovka obyknovennaya (с), Bolotovskoye, Zdorovie, Imrus, Rozhdestvenskoye and Sinap orlovsky were frost hardy unter -40°C. Imrus and Sinap orlovsky showed their frost hardiness of buds and tissues unter -42°C. Under all temperature regimes apple varieties Imrus and Sinap orlovsky were frost hardi enough.
