| Abstract | One-year-old trees without feathers of seven apple cultivars with different susceptibility to scab on M.26 rootstock, were planted in the spring 1998 in Przybroda near Poznan. Six cultivars were genetically resistant to scab: 'Goldstar', 'Topaz', 'Rajka', 'Rubinola', 'Rosana' and 'Odra' whereas 'Sampion' was low susceptible to the disease. Trees were spaced 4.0 x 1.5 m (1667 trees ha -1 ). There was no chemical protection against apple scab. Cultivation of 'Goldstar', 'Topaz', 'Rajka', 'Rubinola', 'Rosana' and 'Odra' was possible without chemical protection against scab while fruit and leaves of 'Sampion' without scab protection were totally infected. The most vigorous cultivars were 'Rajka', 'Rubinola' and 'Topaz', and the least were 'Sampion' and 'Odra'. The highest total fruit yield was obtained from 'Rajka', 'Goldstar', 'Rosana' and 'Topaz' and the lowest from 'Sampion'. 'Goldstar' had the heaviest fruit and 'Odra' the lightest. The biggest fruit had 'Goldstar' and the smallest had 'Rajka'. The best coloured were 'Odra' fruit and the worst coloured were fruit of 'Goldstar'. |
