The paper presents the study on sweet cherry tree training according to naturally improved crownsystem of low volume. The orchard was planted in 2010 using vegetative rootstocks Gisela 6 (Cerasus vulgarisx Prunus canescens) on which the scions of the sweet cherry varieties - Ferrovia, Adriana and Skeena - weregrafted, at the planting distance of 4 x 2 m. The trees extended at a vertical height of 3-4 m, have trunks of 50-60cm height and a well-developed axis, on which two levels of scaffold branches are inserted at a distance of 60-70cm. The first level comprises 3 - 4 branches arranged uniformly in a spiral around the tree axis at a distance of 8-12 cm between them, the next level comprises 3 - 4 scaffold branches extended at a height of 60-70 cm from thoseof the first level. Above the second level, only semi-skeletal and fruit-bearing branches, which are periodicallyreplaced, are placed uniformly around the axis in an oblique position.
