 14 plum cultivars of late maturation period were studied in Belgrade from 2013 to 2017, with Stanley as the control. The average time of flowering was in April and fruit maturation in August-September. Topking had the highest yield per tree, 23.6 kilograms, while Posniplava had the lowest – 10.2 kilograms. Three cultivars achieved significantly lower yields than the control, and three cultivars had significantly higher fruit weights than the control. All studied cultivars had high-soluble solids content, with empress being the best rated for fruit appearance and Anata and Posniplava being best scored for taste.
