                    Fusarium ear rot is one of  the  most  important diseases  of  corn  in Iran. This disease cause by  Fusarium moniliforme fungus. Its  symptoms  are pink to red spots on ear, cause it completely rot and eventually loss of  yield quantity  and quality.  Identification and cultivation resistant or semi-resistant corn hybrids is the best management method of this disease. Artificial infection of maize hybrids with fungal suspension of causal agent is an affective method to study their  reactions, determine base on disease severity index (%DS). According to research conducted in Iran, between  12  planting hybrids,  2  hybrids  K3493 / 1 × K18  and  KLM 77029/8-1-2-3-2-3 × MO17 are resistant, and  9 are semi- resistant . With extension, cultivation  of  these  hybrids, can manage the disease and increase the quality and quantity  of  maize hoped.
