Evaluation of new selection forms of guelder rose (Viburnum opulus L.) on ecological and economically valuable traits

It has been shown that an alternative source of many food components are fruit plants, in particular, Sorbus aucuparia L., Aronia melanocarpa (Michx.) Elliott, Amelanchier canadensis (L.) Medik., Hippophae rhamnoides L., Cydonia oblonga Mill., Viburnum opulus L., Cornus mas L. and others. Their raw materials are a source of vitamins, minerals, dietary fiber and other vital nutrients necessary for the normal maintenance of metabolic processes in the human body. The article focuses on the shortage of genetic resources of Viburnum opulus L., which would meet the requirements of mechanized harvesting, are characterized by high environmental adaptability, as well as meet the requirements of the processing and food industries for consumer quality for the production of functional and health products. New selection forms of Viburnum opulus L. (Strumkova, Horikhova, Krasunya) are characterized by economically valuable traits, morpho-biological traits and properties and biochemical indicators. It is shown that the new forms of guelder rose Strumkova and Krasunya, given the high yields (7.7 and 12.7 kg / plant, respectively) and consumer quality of fruits, are suitable for processing and production of functional products, and the plant form of Horikhova is suitable to the mechanized harvesting of fruits in their technical ripeness, due to low growth (1.8 m) and compactness of a bush, character of placement of fruits on a plant. Based on the successful targeted introduction during 2017–2019 in the research field of the Institute of Horticulture NAAS (Northern Forest-Steppe of Ukraine), more promising (3 samples) were transferred to the National Center for Plant Genetic Resources of Ukraine (NCGRRU). V. Ya. Yuriev NAAS of Ukraine, where after expert evaluation the samples were assigned a catalog number and included in the genetic bank of plants of Ukraine, including: Strumkova, Horikhova, Krasunya which are recommended for the selection process as sources of stable productivity and consumer quality fruits for processing, high resistance to adverse environmental factors.
