Abstract :Apple scab insert ignore into journalissuearticles values(Venturia inaequalis insert ignore into journalissuearticles values(Cke.); Wint.); is a major fungal disease for apples, it causes much economic loses in our country. Fungicidies have been used much to protect from apple scab. Chemical protection’s alternative is using resistant varities. For this reason in 2005–2006 years, 51 apple varities grafted on MM 106 rootstock had been evaluated for apple scab. The apple varities had been tested with natural inoculation and Any fungicide application had not been done in the trial. It had been done according to randomized plots design with 4 replicates. Infection ratio had been tested according to 0-4 scala. Infection ratio values are like these; resistant insert ignore into journalissuearticles values(%0-1 leaf infection);, less sensitive insert ignore into journalissuearticles values(%25>leaf infection);, sensitive insert ignore into journalissuearticles values(%25-50 leaf infection); and much sensitive insert ignore into journalissuearticles values(%50 Keywords : Elma, Venturia inaequalis, dayanıklılık
