In order to evaluate CMV resistance of the radish inbred lines, leaves of twenties radish (Raphanus sativus L.) inbred lines were mechanically inoculated with a strain of Cucumber mosaic virus (CMV) systematically infecting radish plants, respectively. The inoculated radish plants were incubated at 22C3C and resistance assessment was examined using symptom development for 4 weeks. Based on the reactions of differential radish inbred lines, 11 radish lines were produced mosaic, mottling, yellowing and severe mosaic symptoms by CMV infection. These results were confirmed by RT-PCR analysis of CMV coat protein gene, suggesting that CMV is responsible for the disease symptoms. In contrast, 9 resistant radish lines did not induce systemic mosaic symptoms on upper leaves and chlorosis in stem tissues for 4 weeks, showing that the radish plants did not express any symptoms by 8 weeks. Further examination of CMV infection in the 9 resistance-candidate radish lines showed no CMV infection in systemic leaves of the 9 radish lines. Taken together, these results suggest that the 9 radish lines are highly resistant to CMV.
