In the 70’s, at the Fruit Growing Research Station Iaşi, Romania, began a breeding program for sweet cherry and first cultivars have been released after 90’s. The main followed objectives were to improve fruit quality, obtaining self-fertile cultivars, extending the harvest period and achievement cultivars with diseases and pests resistance. Among those released in 2010 nine sweet cherry cultivars were studied between 2007-2011: ‘Alex’, ‘Anda’, ’Cociu’, ‘Margo’, ‘Ludovic’, ‘Mihai’, ‘Andrei’, ‘Iosif’ and ‘Paul’. Some parameters related to phenological stages, diameter, weight, firmness, colour and cracking resistance of fruits, soluble solids content and reducing sugars, titratable acidity, ripening time, diseases and pests resistance, trunk section surface and yield per tree were determined. Largest fruits size (10-11 g) was measured in ‘Ludovic’, ‘Cociu’ and ‘Alex’. ‘Anda’ and ‘Margo’ are yellow, ‘Paul’ is bicolor and all other cultivars have red or dark red skin color. Results showed that soluble solids content ranged from 15 to 17.9°Brix and reducing sugars content ranged from 14-16 g 100 g-1 fruit weight. ‘Margo’ and ‘Andrei’ have a good anthracnose and monilia resistance. Highest values of yield, ranged from 14.5 to 15.2 kg tree-1, have been obtained at ‘Iosif’, ‘Paul’, ‘Ludovic’ and ‘Margo’.
