Seven Mediterranean Ficus carica genotypes, i.e. cv. Palazzo, Severoni precoce, Bianca, Pilusedda, Dottato bianco, Bifara and Zidi, were screened for the presence of seven fig-infecting viruses associated with fig mosaic disease (FMD) in order to explore their distribution in different plant organs (leaf, bud and syconium) that will be utilized as a plant source material in different sanitation techniques. RT-PCR assays conducted on reverse-transcribed TNA extracted from leaves, apical buds and syconia (1.5-2cm) of each genotype for the presence of Fig leaf mottle-associated virus 1 (FLMaV-1), Fig mild mottling-associated virus (FMMaV), Fig mosaic virus (FMV), Fig latent virus 1 (FLV-1), Fig Badnavirus1 (FBV-1) and Fig fleck-associated virus (FFkaV) showed that the infection rates in tested cultivars were 72.2% for FBV, followed by FFkaV (27.4%), FLMaV-1 (18,7%) and FMV (11.1%); whereas FMMaV and FLV-1 were absent. Virus distribution within the different explants showed that FBV1 was the most prevalent in all explants with infection rates ranging between 50% and 83%, whereas FFkaV was mostly concentrated in syconia (39%) and to a lesser extent in buds (32%) and leaves (10%). The highest infection with FLMaV-1 was found in syconia (50%), where, as buds and leaves, showed a mild level of infection (25%). FMV was present in 25% and 8% of tested buds and leaves, respectively, whereas it was absent in syconia
