Fire blight disease caused by Erwinia amylovora is a destructive disease of pome fruits including apple worldwide. Use of resistant cultivars is the most efficient method of disease control. In the present research, we investigated genetic resistance of 89 local and imported commercial apple cultivars in natural contaminated conditions to the bacterial disease using Beltsville scoring system (USDA) in horticulture Research station of Kamalshahr, Karaj (Iran), during triennial observations, 2007-2009. Apple cultivars differed significantly (P
