Technical Abstract: Plant material of rhizoma peanut (Arachis glabrata) of an unknown accession, obtained from the Arachis species collection nursery planted and maintained at the Coastal Plain Research Station, Tifton, GA was recently brought into the greenhouse where ring spots were identified on immature leaves. Tissue samples were tested for virus using ELISA and PCR methods. Results indicated the presence of Peanut mottle virus (PMV). An additional 42 genotypes from the same location planted in 1960 and 1979 were tested from greenhouse material to verify the presence or absence of PMV. An additional five genotypes were ELISA positive for potyvirus. These were further tested by PCR for PMV and two genotypes tested positive for PMV, the original unknown accession and PI 243334. This is the first report of PMV in rhizoma peanut.
