In the conditions of the Republic of Belarus there were presented results of studying of scab (agent – Venturia inaequalis (Coock.) Wint.; conidial stage – Fusicladium dendriticum (Wallr.) Fuck.) resistance of hybrid offspring of apple (Malus) cv. 'Charavnitsa' with Rvi17 gene. In course of the study there were presented results of testing of hybrid family seedlings (Charavnitsa x Syabryna (Rvi6); Charavnitsa x Imrus (Rvi6); Charavnitsa; Berlorusskoe malinovoe + Charavnitsa) with molecular markers. There was analysed scab resistance of hybrid offsprings of Charavnitsa variety (Charavnitsa x Syabryna; Charavnitsa x Imrus; Charavnitsa; Belorusskoe malinovoe + Charavnitsa). Research results showed that the use of this cultivar in crosses with Rvi6 gene sources was highly efficient for pyramiding of the major genes of scab resistance in one genotype. There were obtained 13 new selected (from 2% up to 11%) hybrids with Rvi17 and Rvi6 genes, which showed high field resistance to Venturia inaequalis in epiphytotic conditions for disease development.
