Abstract
The article presents an analysis of the biochemical composition of apple varieties (Malus domestica B.) with immunity to scab. Domestic and foreign apple varieties are used as research objects. Variability in fruits in the content of ascorbic acid (AA), soluble solids (SDS), P-active compounds, and titratable acids was noted. The high content of AA is noted in Uspenskoe, Skala, Bylina, Flagman, Yubilyar apple varieties. Long-term studies have revealed intervarietal differences in biochemical composition and variation of this trait over the years in apples. Varieties with valuable biochemical composition and immunity to scab can be used in organic food production, as well as in further breeding work to improve the quality of fruits.
Highlights
Apple tree takes a leading position in fruit plantations in countries with temperate climate; it is cultivated in almost all climate zones of our country, which is due to the availability, taste, good preservation qualities, and value in the human nutrition system
The nutritional value of apple fruits for people is ensured by the presence of vitamins, trace elements, fiber, and other useful substances, the balance of which in the body provides the basis of healthy immunity [1, 2, 3]
In Switzerland and Denmark, the production of organic foods based on scab immune apple varieties takes about 40%, which shows the best indicators of consumption per capita [4, 7]
Summary
Apple tree takes a leading position in fruit plantations in countries with temperate climate; it is cultivated in almost all climate zones of our country, which is due to the availability, taste, good preservation qualities, and value in the human nutrition system. In Switzerland and Denmark, the production of organic foods based on scab immune apple varieties takes about 40%, which shows the best indicators of consumption per capita [4, 7]. The content of soluble solids (SDS), P-active compounds, and titratable acids in fruits depend on external conditions.
