Summary Eight isolates of Cucumber mosaic virus (CMV) isolated from seven different host species were tested for their virulence on potato cv. Desirée. Three isolates caused a systemic infection, of which one isolate from Asiatic lily (CMV‐P26) and one from cucumber (CMV‐J) appeared to be highly virulent, in contrast to the third isolate (CMV‐M) that originated from cucumber and caused mild symptoms only. These three isolates were transmitted to 26 additional potato cultivars by mechanical inoculation in a greenhouse. All cultivars were infected with at least one CMV isolate and developed local chlorotic symptoms, but only 17 cultivars (including Desiree) developed primary systemic symptoms including necrosis, mosaic and/or malformation of leaves. Furthermore, in only five cultivars (including Desiree) CMV was transmitted to tubers and was subsequently detected in plants of the first and second vegetative progeny, the secondary symptoms of these plants being severe. The observed phenotypic responses of potatoes to CMV were not associated with the maturity type (early or late) or resistance to other viruses. Results of this study indicate a high level of biological variability among CMV isolates and that infection in potato depends on CMV isolate and potato cultivar.
