The main physical traits and chemical organic and inorganic composition of seven promising F-1 plum hybrids and three commercial cultivars (their parents as control cultivars) were investigated under western Serbian conditions. Out of the studied materials, the P-4 hybrid had the best values for fruit mass (57.62 +/- 2.11 g), flash ratio (97.13 +/- 1.55%), soluble solids (19.20 +/- 1.30 degrees Brix), fructose (3.05 +/- 0.19%) and total sugars content (11.78 +/- 0.34%). This hybrid also had the highest content of N (0.89 +/- 0.02%), K (1.71 +/- 0.04%) and Mg (0.26 +/- 0.04%). The all plum promising hybrids and control cultivars contained high K values. The P-4, P-2 and P-3 hybrids were more suitable for drying than the others because of higher soluble solids and total sugar content. The P-6, P-5, and P-1 were considered less suitable for canning than the other selections because of lower soluble solids and sugars content. Also, P-4 was more suitable for fresh consumption because of hig...h organic and mineral content. More of the promising newly-breed hybrids have better fruit quality attributes when compared with control cultivars.
