THE PROSPECT OF USING THE APPLE CULTIVARS OF RUSSIAN RESEARCH INSTITUTE OF FRUIT CROPS BREEDING BREEDING FOR RAW BASE OF JUICE PRODUCTION

Data of technological studying of apple cultivars from the VNIISPK collection for juice production are provided. The immune or highly scab resistant varieties allocated on juice yield which organoleptic qualities are higher or at the level of control ‘Antonovka Obyknovennaya’ are selected. All studying varieties were better than control on technological parameters for juice production. The average values of the key technological indicators were: juice yield – 67.3 %, content of soluble solids – 12.1 %, sum of sugars – 11.2 %, titratable acidity – 0.86 %, the sugars/acidity ratio – 13.8, P-active substances – 72.9 мг/100 г, tasting score – 4.3 points. Cultivars ‘Orlovskoe poles'e’, ‘Orlovskij pioner’, ‘Turgenevskoe’, ‘Spasskoe’, ‘Zaryanka’, ‘Kurnakovskoe’, ‘Rozhdestvenskoe’ fullestly answering to requirements of juice production were especially selected. It is established that the ripening period had an insignificant impact on chemical and technological qualities of apple juice. Cultivars of any ripening period with high suitability for juice production may be chosen thanks to the varietal variability.
