Abstract An isolate of Cucumber mosaic virus was obtained from pepper in Guangzhou.The coat protein(CP)gene was amplified by RT-PCR using the genomic RNA as template and a pair of primers specific to CMV.Results of sequence analysis showed that the isolate was identified as an isolate of CMV，belonging to the subgroupⅠ.Forty-five pepper breeding lines was inoculated with CMV in seedling period.The results showed that 4 lines were resistant to CMV，and 20 lines were middle resistant.Five lines were selected possessing both CMV resistance and excellent agronomic characteristics.
