Replenishment of the bioresource collection of the Subtropical Scientific Centre with varieties of own selection

Abstract

These studies were conducted in the humid subtropics of the Krasnodar Region. The bioresource collection of the Subtropical Scientific Centre is preserved, mobilized, and maintained in living form, comprising 800 varieties of subtropical crops and over 2,000 ornamental flowering plants. The main methods of replenishment are introduction and breeding of new varieties, the value of which lies in their adaptability to local growing conditions. As a result of breeding research at the Centre, 277 varieties of tea, persimmon, mandarin, feijoa, azimina, hazelnut, fig, strawberry, peach, plum, apple, pear, pelargonium, hippeastrum, freesia, anemone, chrysanthemum, gerbera, tulip, primrose, and peony have been obtained. Over the past 6 years (2019–2024), the collection has been supplemented with new varieties resistant to major environmental stress factors, which have high yield, fruit quality, productivity, and ornamental value. In the State Register of Breeding Achievements approved for use, 73 varieties are registered, including 65 varieties of flowering plants and 8 subtropical fruit and nut crops.
