Apple scab, caused by Venturia inaequalis, is considered the most damage disease of the apple growing in Romania. Pyramiding multiple sources of quantitative resistance could be the best way to control the attack of this fungi. A set of forty apple cultivars from the apple gene bank in Pitesti, Romania was evaluated for the presence of two scab resistance genes: Rvi8 and Rvi11. Using marker OPB18, it was made the difference between 2 genes, Rvi2 and Rvi8, located in the same locus (Vr gene). For identification of Rvi11, the SCAR marker, K08, was used and seventeen cultivars amplified the 743 bp fragment that is linked with Rvi11 gene. The results on resistance of apple Romanian cultivars towards economically important disease is necessary for future breeding work and for establishing of new commercial orchards.
