From the aspect of rational use of pesticides and environmental protection, growing cultivars resistant to pests and causal agents of the most serious diseases is one of the most recent trends in modern apple production. the paper present the results of a three-year study on biological characters of scab resistant apple cultivars Rajka and Topaz which were grown under agro-environmental conditions of Čačak. In this study Rajka had earlier blooming time, greater abundance and ripened somewhat earlier than Topaz. Fruits of Topaz were large, oblate. Both cultivars showed high cropping potential, although Topaz had higher fruit quality and yield.
