First report of Pepper vein yellows virus infecting chilli pepper (Capsicum spp.) in Italy.
During 2014 and 2015, commercial crops and germplasm collections of chilli (Capsicum spp.) in Italy were surveyed for the presence of viral diseases. In 2015, 2% of plants from 2 fields located in different provinces of the Lazio region (Viterbo and Roma) and used for germplasm maintenance and seed production of chilli cultivars and species, were observed showing interveinal yellowing or yellow patches and brittleness of leaves. The causal pathogen was identified as Pepper vein yellows virus (PeVYV) based on various molecular analyses. This is thought to be the first report of PeVYV in Italy where it has been detected in 3 of the major species of cultivated chilli, i.e. C. annuum, C. chinense and C. frutescens.
