| Abstract | The results of analysis of biochemical composition and taste qualities of fruits of 20 clones of Jonagold in the conditions of Podillya are presented. Researches during 2013-2015 found that the most dry soluble substances (DSS) are found in the fruits of the clone DP-9 (13,79±0,52%). The highest amount of titrated acids accumulates the fruits of clones DP-2, DP-3 and DP-8 (0,50±0,25 - 0,51±0,11%). Apples of all spontaneous clones and the original variety of Jonagold contain a small amount of ascorbic acid – 5,8 – 9,3 mg / 100 g of crude mass. The ratio of sugars and acids in apple clones of Jonagold during the period of biological ripeness was 16,7±3,48 – 24,4±6,13 and described them as fruits of dessert purpose. Fruit tasting showed that apple clones DP-3, DP-8, DP-13, DP-14, DP-17 and DP-20 have excellent taste and attractive appearance and can be recommended for fresh use | ||
