The paper presents the results of the researches carried out in the period 2015-2017 years regarding the appreciation of the quality of the white seabuckthorn fruits in the conditions of the Republic of Moldova. Introduced varieties of seabuckthorn for the study: 'Nivelina', 'Podarocsadu', 'Otradnaia', 'Trofimovscaia', 'Botanicescaia'. The quality of the fruits is influenced by a number of factors, including the variety or the climatic conditions, on which depends the amount of nutrients accumulated in it. The amount of dry substances in the fruit ranged from 8.3% to 9.24%, the accumulated sugars varied between 1.39-2.56%, the acidity varied between 2.94-4.08%. The amount of coloring and tanning substances accumulated in white seabuckthorn varieties ranged from 38.80- 54.32 mg%, and the vitamin C content in fruits varied between 100.3 mg% - 145.64mg%. The lowest values of the amount of nutrients have been accumulated in the 'Nivelina' variety, and the highest in the 'Otradnaia' and 'Botanicescaia' varieties. Under the conditions of a favorable year (2016), the most adaptable among the studied varieties proved to be 'Trofimovscaia', which increases the quality of the fruits to the sugar/acid ratio of 2.2 times compared to the variety 'Nivelina'.
