The paper presents the study of yields (kg/tree and kg/ha) and major fruit properties (fruit size, fruit mass, dry matter content) of plum cultivars sampled from 70 growing plantings set up in the region of Čačak, Central Serbia. Plum cultivars developed at Fruit Research Institute Čačak are primarily grown in this area, i.e. ‘Čačanska Rana’, ‘Čačanska Lepotica’, ‘Čačanska Najbolja’, ‘Čačanska Rodna’ and ‘Stanley’. The paper includes two-year results. Agroecological conditions over the first year (2006) were optimal for plum growing. However, the second year of study (2007) was reported to be the one with excessive droughts, as regards this region, which directly influenced yield and fruit quality. The effect of drought affected plum cultivars differently, hence, the following comparative analysis performed over several years includes different cultivars grown under identical conditions. Depending on tree age, planting distance and growing technology, average yields in cv ‘Čačanska Rana’, ‘Čačanska Lepotica’, ‘Čačanska Najbolja’, ‘Čačanska Rodna’ and ‘Stanley’ ranged from 10.0 to 50.0 t/ha, 4.0 to 52.1 t/ha, 17.3 to 83.4 t/ha, 20.5 to 47.2 t/ ha and 13.3 to 53.3 t/ha respectively. Superior results were recorded in early cultivars, as these are less rainfall-dependent (‘Čačanska Rana’ and ‘Čačanska Lepotica’). It was steady cropping, ripening time and fruit quality that established these cultivars as highly marketable over the more recent period.
