Sažetak
Nasturtium ringspot virus could be shown to be present in Yugoslavia on Tropaeolum majus. The identification was possible by host reactions, aphid transmission, serological and cross protection tests. Eleven plant species proved to be hitherto unknown experimental hosts of the virus. Two provenances of nasturtium ringspot virus from Yugoslavia and GDR, respectively, were distinguishable by symptomatology but not by serology. All investigated Yugoslavian isolates induced X-bo- dies and three kinds of crystallinic inclusions in the cells of their syste- mically infected hosts, namely polyhedrons, elongated crystals, and para- crystallinic spindles. The German provenance could be distinguished by the fact that it did not induce polyhedric crystals. Therefore the provenances from Yugoslavia and from the GDR are considered as different strains. It is mentioned that Petunia ringspot virus described by Rubio-Huertos has many properties in common with nasturtium ringspot virus and it seems possible that both viruses are related.
