Аннотация

Based on the technological evaluation of 105 immune V_f and highly resistant V_m to scab apple varieties of the All-Russia Research Institute for Horticultural Plant Breeding suitable for juice production, 16 varieties perspective for raw material production are specified with the juice output from 70.4% (Orlovskoe Poles’e) to 65% (Rozhdestvenskoe), the content of the soluble dry substances not lower than 11%, and organoleptic properties higher (4.5–4.3 points) than in the control variety Antonovka obyknovennaya. A higher juice output is reliably defined in the summer varieties as compared to the winter ones. The character of appearance of some technological features of the fruits (juice output, content of soluble dry substances, organic acids, P-active catechins) is specified in the scab immune hybrid apple progeny of 28 hybrid families.
