Using the process of breeding, the native apple varieties well adapted to the climate of Romania can be an interesting premise for inducing natural genetic resistance to Venturia inaequalis. This paper aims to study in detail the terms of phenological and molecular tools a few Romanian old apple varieties, ('Prescurate', 'Gurguiate', 'Săciu', 'Venchi', 'Turnu', 'Calvil alb', 'Sângeriu', 'Iridium' etc) who showed in prior in the field conditions a natural genetic resistance to scab and after these studies could be reconsidered and reassessed in new breeding programs in Romania. For the beginning the screening with molecular markers to highlight the presence or absence of Vf gene, is the first step in reconsidering these old varieties of apple.
