The All-Russian Scientific Research Institute for Breeding Fruit Crops is the oldest pomological institution. The scientific direction of the institute is to obtain genotypes of fruit crops that exceed the standard ones in terms of basic economic indicators, including those with an improved chemical composition of fruits. The leading culture is the apple tree. One of the indicators of the chemical composition of apples is the presence of phenolic compounds, the most important natural antioxidants: catechins and polyphenols. Genotypes of different maturation periods, immune (Rvi6) and resistant (Rvi5) to scab, diploids (2x) and triploids (3x), vigorous and intensive type (Co gene), were identified as sources of the studied traits. The best in terms of the accumulation of catechins were the varieties of the autumn ripening period: Sokovinka, Slavyanin, Pamyat Isaeva, Zaryanka, Orlovsky pioneer, origin Antonovka red barrel × SR0523 (159.0-288.0 mg / 100 g); the summer varieties Zhelnoe, Orlovim, Early aloe, Anniversary (152.0-170.0 mg / 100 g), the winter varieties Kurnakovskoe, Olympic, Poetry, Freshness, Bezhin meadow, Kulikovskoe, Start, Health, Academician Savelyev, Festive, Orlovskaya Zarya, Pamyati Blynsky, Vita, Mars, Imrus, Pamyati Semakina, Celandine, Kandil Orlovsky, Morning Star, (161.2-353.5 mg / 100 g). The sources of the total amount of polyphenols (more than 400.0 mg / 100 g) were selected: with the Rvi6 gene Start, Zaryanka, Ivanovskoe, Imrus, Oryol woodland, Zdorov’e, Bolotovskoe, Pamyati Khitrovo, Kandil Orlovsky; with the Rvi5 gene Orlovsky pioneer and Celandine; triploids Memory Semakin, Bezhin lug, Turgenevskoe, Mars, Orlovsky partisan, Trainer Petrov, Patriot, Augusta (404.0-623.9 mg / 100 g), of which the varieties Mars and Trainer Petrov have the Rvi6 gene.
