Carnation is one of the main products of cut flowers in Iran. This plant is attacked by various viruses. These viruses reduce the plant vigorous and reduce production efficiency. One of these specific viruses that cause delay in flowering carnation and decreasing of flowers production with high quality to be carnation etched ring virus. In order to evaluation of biological characteristics and distribution of this virus in the Mahallat area, sampling was conducted in carnation greenhouses. After transferring the samples to the laboratory, using specific antiserum CERV and CarMV with DAS-ELISA test were studied. Only samples that were infected with the CERV were inoculated to suitable indicator plants. The results on the distribution of the virus showed that 75% of samples collected from eight greenhouses in three different seasons of the year were infected with the virus. The results also showed that the samples collected were infected with CarMV. Severity of infection in samples with mixed infection with CarMV was lower that samples that were infected only with CERV. Different variety of carnation don't have significantly difference in diseases severity. Key words: CERV, CarMV, DAS_ELISA, Distribution, serology
