Arachis spp. PI 262794, 262817, 421707, 468141, 468144, 468170, 468174, 468345, 468363, 468366, 468370 and 468371 were resistant to mechanical infection with peanut mottle (PMV), peanut stripe (PStV) and tomato spotted wilt viruses(TSWV). PI 262817, 421707 and 468363 (all in the section Rhizomatosae) did not show infection after graft inoculation with tissue singly infected with either PMV, PStV or TSWV. When three scions, each infected with one of the viruses, were grafted on the same plant, only PI 262817 remained virus free.
