PHENOLIC (P-ACTIVE) COMPOUNDS OF BERRY CROPS OF THE VNIISPK GENE POOL

Abstract

Human health is directly related to its nutrition. The most valuable are biologically active substances contained in fruits and berries, including phenolic compounds with the greatest antioxidant activity. Berry crops that have a rapid fruiting are of particular value. The purpose of these studies was to give a comparative assessment of the content of phenolic compounds in the berries of the most common berry crops in central Russia (21 strawberry cultivars, 26 raspberries, 21 gooseberries, 59 red currants, 64 black currants) and to identify the best genotypes as sources of high content of phenolic substances in berries for use in breeding programs. The content of anthocyanins, catechins, leucoanthocyanins and their amount were determined in berries. Berry cultivars including cultivars of VNIISPK breeding with high values of the studied components were identified: gooseberry – Nekrasovsky, red currant – Osipovskaya, black currant – Arapka, Nyura and Yubiley Orla for the content of anthocyanins; red currants Belka, Podarok Pobediteliam, Selianochka and Ustina, black currants Assol, Zusha, Kipiana, Muravushka, Nyura, Orlovia and Yubiley Orla for the content of catechines; red currants Podarok Pobediteliam and Selianochka, black currants Assol and Gratsia for the content of leucoanthocyanins; gooseberry Nekrasovsky, red currant Podarok Pobediteliam, black currants Assol and Yubiley Orla for the amount of phenolic compounds. The genotypes with a complex of all the studied substances (anthocyanins, catechins, leucoanthocyanins) are of the greatest interest: strawberries – Darselect, Rubino civ, and Rusich, raspberries – Lazarevskaya, gooseberries – Kazachok and black currants – Glarioza.
