Abstract Production technology and volumes of planting material of promising and new forms and varieties of Japanese quince for use in landscaping and creation of architectural compositions do not satisfy the needs of landscape gardening in Ukraine. The reason for this is that the existing methods of reproduction of Japanese quince are time consuming, and do not always provide a stable result, which inhibits the spread of culture. The aim of the research was to study the regenerative ability of green stem cuttings of promising varieties of Japanese quince and to refine some agro-technological measures of reproduction in the Right-Bank Forest-Steppe of Ukraine. It was found that the stem cuttings of the studied varieties of Japanese quince have different regenerative capacity: Nicholas, Vitamin, Orange, Karavaevsky belong to the medium-rooted, and Citrine, Nika and Calif to the hard-rooted. It was proved that the optimal time for harvesting green stem cuttings of all studied varieties of Japanese quince and planting them for rooting is the phase of intensive growth of shoots – June 1–20. The dominant influence on the rooting of cuttings of the studied varieties is caused by the factor "part of the shoot and its metamerism" – 25–40 %. Significantly higher rooting in three-node cuttings harvested from the apical part of the shoot, cuttings from the medial and basal parts have a weak root-forming ability throughout the period of rooting. We recommend using the studied varieties of Japanese quince for landscaping and growing in the conditions of the Right Bank Forest-Steppe of Ukraine in gardens, parks, squares, cottages and homesteads not only as ornamental but also aromatic, edible and medicinal plants. It is necessary to take into account the decorative features of plants – habit, height, crown shape, color and shape of the leaves, both during the growing season and in autumn; color of flowers, term of flowering, its duration; size and shape of fruits and their color.
