Charcoal rot is one of the most important diseases of sunflower in the world. The disease is threat for the sunflower crops in north of Iran. Different methods were applied for the disease management. The use ofresistant cultivarsis considered as one of the most important methods. In this study ten sunflower genotypes obtained from the seed and plant improvement institute of Iran, were evaluated to Macrophomina phaseolina. In this experimentresponse of the genotypes was investigated against to charcoal rot in vitro and farm condition.In vitro study showed that genotype RF81–74*AF80–460\2\1with 39.89 and genotype RF81137\1*AF81–228with 50.67 had lowest and highest disease index. In the farm condition genotypes RF8174*AF80–460\2\1, RF81–1\2*AF81–112, RF81–1\2*AF80–452\2\2, RF81–106\1*AF80–448\1\2, HYSUN33 and AZARGOL showed significantly low incidence of Macrophomina phaseolina (0.33%) followed by genotype RF81–65*AF80–429\2\3 (13.67%).The results demonstrated different response of sunflower genotypes to Macrophomina phaseolina.
