Fermentable sugars (the total of glucose, fructose, and sucrose), sorbitol content, dry matter content, and titrable acidity were monitored in fruits of 16 new plum cultivars from the harvests in 2004-2007. General linear model of two-factor grouping with testing of significance of simple contrasts with LSD method was used for statistical evaluation of plum cultivar chemical characteristics. Based on these results the tested cultivars were further divided into groups as regards their future processing into prunes, damson cheese or distillates. The traditional cultivar Italian Prune, grown in parallel, was used as the reference standard. Cvs. Gabrovska, Chrudimer, Elena, Hamanova, and President showed the best results and can be recommended for the production of distillates as well as prunes and damson cheese. Katinka, Anna Spath, and Veeblue are preferable for the production of distillates. Valjevka and Cacanska lepotica are suitable for processing into prunes and damson cheese. Substandard values of the studied characteristics were determined in Cacanska najbolja, Hanita and Voyageur. Cvs. Bluefree, Stanley, and Valor were evaluated as the worst ones.
