Popis: Pomegranate has gained considerable popularity in many countries worldwide due to its health benefits. The competitive nature of fruit marketing forces improving the quality attributes, while keeping yield at an optimum level. To pursue this objective, in 2012 in the Ravenna province of the Emilia Romagna region (Italy) was established one coll ection field, wherein 57 cvs. from different countries of the world are maintained. As pomegranate is propagated by hardwood cuttings, healthy propagation material is required to avoid virus epidemics. We therefore focused our research on this collection field, which may play a pivotal role to spread new pomegranate propagation material. Moreover, we recently reported cherry leaf roll virus (CLRV) in the collection field and in a consistent amount of ornamental pomegranate plants in public gardens in Bologna (almost 10% of the analyzed samples, two expressing leaf deformation symptoms). Field inspections during spring 2015 showed several cvs. exhibiting virus-like symptoms on the leaves such as calico mosaic, chlorotic rings and malformations suggesting infection by some viral agent. Serological (ELISA) and molecular analysis (RT-PCR) are ongoing on leaf extracts from all 57 cvs., most symptomless, in order to detect the presence of several viruses such as: alfa alfa mosaic virus (AMV), arabis mosic virus (ArMV), CLRV, cucumber mosaic virus (CMV), strawberry latent ringspot virus (SLRV), tobacco ringspot virus (TRSV) and tomato ringspot virus (ToRSV)
