Abstrakt
The blue honeysuckle (Lonicera caerulea L.) is a relatively new crop in Ukraine, its
industrial cultivation is only 100 hectares. The main constraints are the lack of varieties with high
yield and nutritional value of berries. Therefore, a study of the yield and quality of introduced
varieties is necessary and relevant, both for producers and breeders. With our research, we
determined the potential of the early stage of blue honeysuckle berries under the conditions of
their cultivation in the Forest Steppe of Ukraine and the weather conditions of the year of the
specified region. We assessed how early we can get a crop and set what quality and what it will
be. To clearly understand the quality of the grown fruits, their average weight, size and uniformity
were studied. From nutritional indicators of fruit quality, the content of dry matter, soluble solids,
sugars and titrated acids was studied, from biologically active substances, the content of vitamin
C and total phenolic was determined. It was found that in the zone of the Forest Steppe of Ukraine
from the studied group of varieties, the highest yield potential, 3.13 kg from a bush for the second
year of fruiting and fruit mass 2.4 g, had a variety of Canadian breeding ‘Boreal Beauty’. The
fruits of the cultivars ‘Duet’ (4.3) and ‘Boreal Blizzard’ (4.5) were distinguished by the balance
of taste according to the sugar-acid index, and the maximum amount of total phenolics for the
studied group of varieties was accumulated by the fruits of ‘Boreal Beast’ (1,000 mg 100 g-1
).
