Experimental data on the content of total polyphenols and rutin in promising feijoa varieties selected by the Subtropical Scientific Center (Sochi, Russia) are presented. The performed analysis did not reveal a correlation between the content of rutin and polyphenols (r = 0.40), as well as a relationship between the time of fruit ripening and the amount of phenolic compounds in them. The compared varieties differ significantly in the content of polyphenols (LSD=5.67) and rutin (LSD=1.5). The results obtained revealed promising varieties with a high content of polyphenols that can be used for breeding work as sources of valuable traits and as functional food products with antioxidant activity. The highest polyphenolic content was found in fruits of cv. Dachnaja (41.16 mg/100 g of raw weight). The highest content of rutin was found in fruits of cv. Dagomysskaja (42.1 mg/100 g of raw weight), cv. Dachnaja (38.4 mg/100 g) and control cv. Superba (36.8 mg/100 g). The minimum level of synthesis of flavonoid compounds was found in the ShV-07 form. Since the factor of genotypic features of varieties is essential in the accumulation of phenolic compounds, it became possible to select an assortment characterized by an optimal content of phenolic compounds.
