A survey of grapevine viruses present in the region of Calabria (southern Italy) was carried out, and the sanitary selection was conducted on various indigenous varieties. Serological (ELISA) and molecular (multiplex RT-PCR) tests were used to detect the viruses included in the Italian certification programme: Arabis mosaic virus (ArMV), Grapevine fanleaf virus (GFLV), Grapevine leafroll associated virus 1 (GLRaV-1), Grapevine leafroll associated virus 2 (GLRaV-2), Grapevine leafroll associated virus 3 (GLRaV-3), Grapevine virus A (GVA), Grapevine virus B (GVB) and Grapevine fleck virus (GFkV). The frequency with which the above viruses have been detected was 37.4, 32.6, 12.8, 7.7, 7.3, 1.9 and 0.3%, respectively, for GVA, GLRaV-3, GFLV, GFKV, GLRaV-1, GLRaV-2 and GVB. ArMV was never found. The sanitary selection allowed for the detection of 6 putative clones of ‘Arvino’, 2 of ‘Magliocco dolce’ and 2 of the rootstock ‘17–37’ free of the above-mentioned viruses. The necessary process for the commercialization of these clones as ‘certified’ propagation material was accomplished, and their official approval by the Italian Ministry of Agriculture is currently in progress.

Abstract
A survey of grapevine viruses present in the region of Calabria (southern Italy) was carried out, and the sanitary selection was conducted on various indigenous varieties. Serological (ELISA) and molecular (multiplex RT-PCR) tests were used to detect the viruses included in the Italian certification programme: Arabis mosaic virus (ArMV), Grapevine fanleaf virus (GFLV), Grapevine leafroll associated virus 1 (GLRaV-1), Grapevine leafroll associated virus 2 (GLRaV-2), Grapevine leafroll associated virus 3 (GLRaV-3), Grapevine virus A (GVA), Grapevine virus B (GVB) and Grapevine fleck virus (GFkV). The frequency with which the above viruses have been detected was 37.4, 32.6, 12.8, 7.7, 7.3, 1.9 and 0.3%, respectively, for GVA, GLRaV-3, GFLV, GFKV, GLRaV-1, GLRaV-2 and GVB. ArMV was never found. The sanitary selection allowed for the detection of 6 putative clones of ‘Arvino’, 2 of ‘Magliocco dolce’ and 2 of the rootstock ‘17–37’ free of the above-mentioned viruses. The necessary process for the commercialization of these clones as ‘certified’ propagation material was accomplished, and their official approval by the Italian Ministry of Agriculture is currently in progress.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
