In the experiment conducted in 1998-2002, the growth and yield of 10 scab-resistant apple cultivars were estimated at the Fruit Experimental Station, Samotwór near Wrocław. The experiment was carried out using a randomised split-plot design, in 4 replications, with 5 trees per plot. Spacing was 3.5×1.2 m (2380 trees per 1 ha). The results of five years study confirmed that ‘Florina’ (control), ‘Sawa’, ‘Rubinola’, and ‘Topaz’ cultivars are the most attractive. M.9 and P 60 rootstocks was found to be the most useful for the studied apple cultivars. The trees of most cultivars on these rootstocks gave high and early crops of large apples.
