Abstract

In Romania, 70 ameliorated varieties were created starting in 1996 and until now. Some of them show resistance to scab, being carriers of some genes described in various specialized works, but, for some time, a decrease in resistance to the pathogen Venturia inaequalis has been observed in varieties known to be resistant, so must be initiated a reorganization of the hybridization in breeding programs. In this study, a molecular screening was performed for some of the parents that were used to create the varieties in breeding programs from Romania. The apple varieties introduced in this study were differentiated with the following molecular markers: AL07, AM19, Vfc for the Rvi6 gene; OPL19 for Rvi2 and Rvi8 gene; AD13 for the Rvi4 gene, respectively OPB12 and Hi07ho2 for the Rvi5 gene, some of the varieties being identified as carrier more than two resistance genes ('Florina', 'Romus 3’, 'Romus 4’, 'Romus 5’, 'Pionier’ and 'Starkrimson’).
