Fruit physicochemical parameters are essential for evaluating the new cultivars when tested in new planting conditions. The article presents the fruit's biochemical characteristics during four-year research (20 9-2022) for 30 peach and nectarine cultivars. The orchard was established in 20 7 in the Experimental Field of the Faculty of Horticulture in Bucharest with Romanian and foreign cultivars grafted on Myrobalan 29C, Saint Julien A, Adesoto, and GF677 rootstocks. Vertical Axis and Trident were used as planting systems, and an integrated orchard technology was applied. The size, average weight, flesh firmness, soluble solids, dry matter, titratable acidity, fructose and glucose content, and absorbance index were measured/determined for fruit evaluation. The results present the range intervals for all monitored parameters and the distribution of the cultivars on clusters depending on the physical and biochemical parameters. At the same time, the rootstock and system planting influence on the fruit parameters are highlighted.
