The study subjects were 6 plum cultivars of the European assortment as: ‘Pitestean’ (C), ‘Cacanska Najbolia’, ‘Empresso’, ‘Stanley’, ‘Blue Free’ and ‘President’, grafted on the Myrobalan seedling rootstock, planting distance 5.0x3.0 m, crown shape naturally pyramid. During the research, the trunk diameter and growth, trunk cross-sectional area, development of phenological phases of fruiting bodies, number of fruits, their average weight, fruit yield per tree and per unit area were studied. In the reference period it was established that the cultivars ‘Piteșteanca’, ‘Cacanska Najbolia’, ‘Empresso’, ‘Stanley’, ‘Blue Free’ and ‘President’ allow to obtain yields from 11.7 to 25.4 t/ha of competitive quality, distributed over 45 harvesting days.
