In Italy, for protecting kiwifruit (Actinidia spp.) production by restraining the spread of new and harmful diseases on both nurseries and orchards, a specific Decree has been issued by the Italian Ministry for Agriculture, Food and Forest Policies (Decree 7th February 2011 – published in the Official Journal of the Italian Republic n. 69 25th March 2011). According to this Decree, primary source material must be free, at least, from 6 different virus species: Actinidia virus A (AVA), Alfaalfa mosaic virus (AMV), Apple stem grooving virus (ASGV), Citrus leaf blotch virus (CLBV), Cucumber mosaic virus (CMV), Ribgrass mosaic virus (RMV) and also from the Stolbur phytoplasma Candidatus Phytoplasma solani). Deeper information on biological and molecular proprieties of kiwifruit viruses is therefore necessary to ensure the development of diagnostic tools for a rapid, sensitive and reliable analysis of kiwifruit vegetative propagation material. A CMV isolate (K35) has been recently identified in kiwifruit plants collected in Emilia Romagna (northern Italy). A deep molecular characterization of this isolate has been done to establish the virus origin. Moreover, agroinfectious K35 clones have been produced with the purpose to infect new kiwifruit plants on which to perform studies on natural transmission of the virus and evaluate performances of developed detection methodologies. New viral isolates have been identified during survey carried out in 2011. Molecular characterization is in progress, but these new reports suggest that viral infections occur more extensively than expected on Italian kiwifruit nurseries and orchards.

Abstract
In Italy, for protecting kiwifruit (Actinidia spp.) production by restraining the spread of new and harmful diseases on both nurseries and orchards, a specific Decree has been issued by the Italian Ministry for Agriculture, Food and Forest Policies (Decree 7th February 2011 – published in the Official Journal of the Italian Republic n. 69 25th March 2011). According to this Decree, primary source material must be free, at least, from 6 different virus species: Actinidia virus A (AVA), Alfaalfa mosaic virus (AMV), Apple stem grooving virus (ASGV), Citrus leaf blotch virus (CLBV), Cucumber mosaic virus (CMV), Ribgrass mosaic virus (RMV) and also from the Stolbur phytoplasma Candidatus Phytoplasma solani). Deeper information on biological and molecular proprieties of kiwifruit viruses is therefore necessary to ensure the development of diagnostic tools for a rapid, sensitive and reliable analysis of kiwifruit vegetative propagation material. A CMV isolate (K35) has been recently identified in kiwifruit plants collected in Emilia Romagna (northern Italy). A deep molecular characterization of this isolate has been done to establish the virus origin. Moreover, agroinfectious K35 clones have been produced with the purpose to infect new kiwifruit plants on which to perform studies on natural transmission of the virus and evaluate performances of developed detection methodologies. New viral isolates have been identified during survey carried out in 2011. Molecular characterization is in progress, but these new reports suggest that viral infections occur more extensively than expected on Italian kiwifruit nurseries and orchards.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
