APPLE CULTIVARS AND HYBRIDS FOR JUICE PRODUCTION
Today, the production of Russian apple juice concentrate from domestic raw material provides the needs of the juice industry no more than 21 %. Restoration of the domestic raw material base of the juice production is the most important task, the solution of which is impossible without expanding the areas under the intensive plantations laid using the specially selected immune or scab-resistant varieties guaranteed for stable production of environmentally safe and inexpensive raw material. Our research was directed to study the suitability of immune and scab-resistant apple varieties and hybrids of the Institute of Breeding Fruit Crops for juice production, the selection among them the best varieties with chemical and technological qualities of fruits promising for cultivation in the raw gardens and using in breeding for high technological qualities of fruits. Apple cultivars of Institute Of Fruit Crop Breeding have been assessed for juice output and quality of natural juice from fruits. When selecting the cultivars for juice production we took into consideration not only juice output but also the contents of soluble dry substances, sum of sugars, titrate acidity and P-active substances. General taste estimation was given to the juice obtained from apple fruits of different dates of maturing. As a result of the long-term breeding work two apple cultivars, Zaryanka and Sokovinka, have been released from the family of Antonovka Krasnobochka x SR 0523 for juice production. Zaryanka has been included in the State Register of Breeding Achievements Admitted for Use (regionalized) and Sokovinka is suggested for state testing. These cultivars exceed control Antonovka Obyknovennaya in juice output and taste marking of juice, according to our experiments.
