Monitoring of mulberry (Morus L.) plantations to identify samples that combine high productivity and decorativeness

Abstract

Aim. The purpose of the research was to identify unique mulberry specimens in the existing plantations, adapted to the climatic conditions of the growth zone, with a different combination of economic characteristics. The collection of the dendrological park "Ustimivskyi", protective strips within the land use of the Ustymivska Experimental Station of Plant Production of Plant Production Institute nd. a. V. Ya. Yuriev of NAAS, private estates of residents of the villages of Ustymivka and Novobudova of the Globynska UTC of the Poltava region. Results and Discussion. Among the mulberry plants growing in the collection of the Arboretum, one can single out sample УП33 as the sweetest of the examined samples. УП21 has large fruits 2-3 cm long, pale pink, when fully ripe - purple; whole leaf, large, 20-25 cm long, dark green. On the territory of the introduction-quarantine nursery of the station, the sample КР1 grows, which has only male inflorescences and a leaf blade 15-18 cm long and is recommended as a decorative one. In the village Newly, the HC1 sample deserves attention - a tree with dark purple sub-fruits 2.5-3 cm long, the fruits are pleasant to the taste, the leaf is small, leathery. Sample HC2 has white subfruits up to 2 cm long, when fully ripe they are faintly sweet, but without a pronounced specific taste, the leaves are small, smooth on both sides. In 1952-1954, between the fields of the experimental station, for feeding silkworms, a forest strip was planted, where you can distinguish the ЛЯ4 sample with dark purple fruits up to 2 cm long with a neutral, but pleasant taste. In sample ЛЯ5, individual fruitlets in the subfruit are large, red-purple, which remain shiny when overripe. Among the samples growing in the homesteads of the residents of the villages of Ustymivka and Novobudoka, a number of samples can be singled out (УВ7, УВ14, УВ24, УН2, УБ1, НХ1), which combine high taste qualities and the size of the leaf plates. Conclusions. Along with basic varieties and species, seedlings with an interesting combination of economic and valuable traits are growing on the surveyed territories, which deserve further study and use in selection programs and greening of settlements.
