Rezumat

In recent years, the mobilization and selection of new taxa of non-traditional fruiting shrubs that exceed the available ones in terms of fruit productivity and are rich in biologically active substances, resistant to drought and frost, immue to diseases and pests. The research was conducted in 2018-2021, in the introduction nursery of the Dendrology Laboratory of NBGI, in the framework of the project 20.80009.7007.19. We used as research subjects the plants that had been recently introduced in the collection of the NBGI, from which fruits and cuttings were taken. The phenological observations were made according to the method developed at the Moscow Botanical Garden and perfected by Dr. hab. A. Palancean. The new taxa, grow well, are resistant to drought and frost and bloom starting with the first year after planting, bear fruit regularly and abundantly. The leaves are lanceolate, green on the upper side and silver with brown spots on the lower side, alternate, 4-10 cm long and 2-4 cm wide, with undulate margin. The researched taxa are similar to the species, grow fast, the flowers are actinomorphic, bisexual, yellowish, type 4, the androecium consists of 4 stamens, the ovary is 1-locular. The flowers are grouped by 1-3 in short racemes, rarely solitary; develop in the basal part of annual shoots. ‘Fortunella’ can be easily distinguished from the other 2 cultivars due to its larger fruits and seeds, denser flowers and fruits on a 20 cm long shoot, and “Amoroso” – due to its smaller fruits. The plant blooms in April-May, depending on the climatic conditions during that period. The fruits are ellipsoidal drupes, edible, with a sweet-sour taste, about 1 cm long, of different yellowish or red colours, depending on the cultivated variety, and densely arranged on shoots developed in the previous or current year. The fruits ripen at the end of August and remain on the branches until October. The researched taxa differ in flower colour, flower density per stalk, number of flower stalks per shoot from the previous year, average weight of fruits and seeds and their size, mesocarp yield and percentage of fruit bearing.
