The study of Aronia original selection material and selection of the best varieties and forms on the economically valuable parameters are presented. In 2017–2021 two chokeberry varieties (Viking and Hugin) and three forms (Mavka, Form 4-17, and Form 11/2-17) in the collection of the Institute of Horticulture of NAAS of Ukraine were selected according to the complex biological characteristics (weight of 1 brush, yield from the bush, organoleptic properties, biochemical composition of fruits, resistance to pathogens) for further selection work. Organoleptic parameters and biochemical composition evaluate the chokeberry fruits; the best of them are selected by the content of dry matter (Mavka and Form 11/2-17), dry soluble substances (Mavka and Viking), polyphenolic compounds (Hugin and Form 11/2-17), P-active substances, taste and aftertaste (Form 4-17, Hugin). All studied genotypes of Aronia are characterized by high decorativeness (shape and colo? of inflorescences, duration of flowering, color, and shades of leaves during the growing season). As a result of a phytosanitary assessment of Aronia plantations, it was found that the plants are in excellent condition, the degree of manifestation of the leaf spot is insignificant, the presence of quarantine diseases was not detected. Viking variety, Mavka, and Form 11/2-17 were immune and practically resistant to Phyllosticta arbutifolia and Erwinia amylovora for four years of research. The analysis of the obtained results confirms the appropriateness of using Aronia varieties (Hugin and Viking) and new forms (Mavka, Form 4-17, and Form 11/2-17) in fruit and ornamental horticulture.
