The properties of a virus causing walnut ringspot ofJuglans regia L. which had been identified by the visual examination of symptoms on leaves and fruits of walnut trees in Slovakia were studied. The virus was transmitted mechanically toChenopodium quinoa Willd.,Chenopodium amaranticolor Coste et Reyn.,Nicotiana clevelandii Gray,Phaseolus vulgaris L. cv. Bountiful. Purified virus was used for antiserum production. The thermal inactivation point of the virus lies between 48 and 50 °C and the dilution end-point between 10-1 and 10-2. The obtained antiserum had a titer 1:256. Virus isolates gave a positive immunological reaction with the Mircetich's antiserum against the cherry leaf roll virus obtained from walnut tree.
