Phenological and pomological properties of nine introduced sweet cherry cultivars ‡ ‘Burlat’, ‘Early Bigi’, ‘Early Lory’, ‘Early Star’, ‘Junska Rana’, ‘Newstar’, ‘Merchant’, ‘Sunburst’ and ‘Vega’, were studied in the vicinity of Čačak, during the two-year period (2018‡2019). The investigation included morphometrical characteristics of fruit (fruit and stone weight; fruit dimensions ‡ height, width and thickness; stalk length; fruit shape index; stone share), biochemical composition of fruit (soluble solids content; total sugars, inverted sugars and sucrose contents; total acids content; fruit juice pH, and sweetness index). The cultivars were characterized by medium-early to medium-late flowering time, and ripening span from 2nd to 4th ripening-week of cherry season. The highest value of fruit weight was found in ‘Sunburst’ (4th week of cherry ripening season) and ‘Early Star’ (2nd week of cherry ripening season). The chemical analyses also pointed to the high quality of fruits for these two cultivars, so they can be recommended for the commercial sweet cherry orchards in the Republic of Serbia, in order to improve assortment structure, and to extend harvesting season. ‘Merchant’ was also characterized with exceptional quality, in terms of biochemical composition of fruits. In relation to early ripening time (earlier than ‘Burlat’), cultivar ‘Early Bigi’ showed high values of quality parameters. Both ‘Merchant’ and ‘Early Bigi’ could be the part of sweet cherry assortment in a smaller extent, after verification in production conditions, and in the areas where they give good results.
