Seven wild rhizomatous peanut introductions [PI 262794, PI 262818, AM 3867, ‘Florigraze’ (PI 421707), PI 172223, ‘Arbrook’ (PI 262817), and ‘Arblick’ (PI 262839)] from the Plant Materials Center, Americus, Ga. were not infected with peanut mottle virus (PMV) by mechanical inoculation, aphid inoculation, or by natural infection when field planted near infected Arachis hypogaea L. These accessions are the only known sources of resistance to PMV in Arachis.
