The results of a comparative study of the biochemical composition of fruits of 5 new introduced varieties of blue honeysuckle (Lonicera edulis Turcz.ex Freyn.) – Aurora, Honeybee, Indigo Gem, Wojtek, Zojka and the zoned variety Leningradsky giant, selected as a comparison standard, are presented. The studies were carried out in 2021–2023. in the southern agro-climatic zone of Belarus against the background of contrasting weather conditions of the growing season. The content of dry, pectin and tannins, free organic, ascorbic and hydroxycinnamic acids, soluble sugars, anthocyanin pigments, flavonols, catechins and the sugar-acid index were determined. A significant influence of the hydrothermal regime of the season on the integral level of nutritional and vitamin value of honeysuckle fruits, estimated by the totality of the indicated biochemical characteristics, has been established. Based on the averaged results of three years of research, it was found that among the new tested taxa of honeysuckle, the most promising in terms of the qualitative composition of fruits compared to the variety Leningradsky giant are the varieties Zojka and Wojtek, while the least promising is the variety Aurora, lagging behind the leading taxa in this trait by 3,3 times.
