Powdery mildew is one of the most important diseases of alfalfa crops in Iran. Leveillula taurica which is the main causal pathogen on alfalfa, has a wide host range and distributed in warm and arid areas of the world. Planting the resistant and moderately resistant cultivars is the most appropriate method to control the powdery mildew of alfalfa. Based on field trials in Iran, the cultivars Codi and Gharehyonjeh are moderately resistant Bami is moderately susceptible Hamedani 121 and Hamedani 122 are susceptible and Mohajeran, Simertchenskaya, Diablorde and Ranger are highly susceptible to this disease. Accordingly, Codi and Gharehyonjeh which are the moderately resistant cultivars can be used for management of this disease.
