The phenological characteristics, yield and fruit quality of 11 early and mid-early season nectarine cultivars were studied during the three-year period (2021–2023) in the Belgrade area. The training system in the experimental orchard is Sloping Leader, a new original system with a very high planting density (3.5 × 1 m or 2857 trees per hectare). The cultivar ‘Caldesi 2000ʼ was used as a control for comparison. Compared to the control cultivar, flowering started on average between 9 days earlier (‘Early Bombaʼ) and 2 days later (‘Maria Laura’). The average harvest time was between June 26 (‘Early Bombaʼ) and July 28 (‘Maria Martaʼ). The lowest average yield per tree (4.4 kg) was achieved with the cultivar ‘Early Bombaʼ, and the highest (10.8 kg) with the control cultivar, ‘Caldesi 2000ʼ. Compared to the control cultivar, a significantly lower yield was achieved with 8 cultivars. The average fruit weight was highest in the cultivar ‘Big Havenʼ (180.1 g) and lowest in the cultivar ‘Rita Starʼ (114.6 g). Compared to the control cultivar, the fruit weight was significantly lower in 7 cultivars. The soluble solids content ranged from 12.3% (‘Rita Starʼ) to 17.7% (‘Maria Lauraʼ), and the total acid content ranged from 0.59% (‘Big Bangʼ) to 1.07% (‘Caldesi 2000ʼ). The cultivars ‘Big Havenʼ, ‘Big Bangʼ, and ‘Amigaʼ achieved the highest scores for fruit appearance, and the cultivars ‛Big Haven’, and ‘Big Bangʼ for taste. Based on the results obtained, the cultivars ‘Big Havenʼ, ‘Big Bangʼ and ‘Amigaʼ, together with the control cultivar ‘Caldesi 2000ʼ, can be recommended for cultivation in the Belgrade region.
