LEPL Scientific-Research Center of Agriculture, Division of Fruit-growing Research, Abstract There are given the results of the assessments of prospective introduced cultivars of cherry In Georgia. The research has been carried out in the collection orchard of the experimental station Jigaura of LEPL Scientific-Research Center of Agriculture (SRCA) in the 2018-2022. The following agronomic and biological characteristics were studied according to the cultivar: phenological phases of development, detailed pomological description of tree, susceptibility toward diseases, biochemical and mechanical analysis of fruits and other features. According to the study data, cultivars: Schattenmorelle, Karneol, Montmorency are characterized by high productivity and good fruit characteristics and could be recommended for the improvement of assortments of cherry in East regions of Georgia. Key words: fruit, variety, flower, pollination, harvest
