A collection of 147 Potato virus Y (PVY) isolates from tomato, originating from several commercial fields and greenhouses in different regions of Poland, was tested for the presence of PVY by reverse-transcription polymerase chain reaction. However, in some cases, the results obtained were ambiguous. Therefore, a sensitive reverse-transcription loop-mediated isothermal amplification method was developed for rapid detection of PVY isolates. Phylogenetic and recombination analyses were performed based on sequences of the coat protein gene. In comparison with results obtained in 2008, the presence of other strains besides PVY(N)Wi-P was confirmed. A novel recombinant between PVYNTN and PVY(N)Wi-P strains was detected. Our results indicate an increasing distribution and variability of the PVY population on tomato in Poland.
