Fifty four wild Arachis germplasm accessions were evaluated for resistance to peanut stripe virus (PStV) by mechanical, aphid, and graft inoculations. Three weeks after inoculation, inoculated and subsequently produced leaflets of each entry were tested for PStV presence by enzyme-linked immunosorbent assay (ELISA). Peanut accessions in the section Arachis, A. cardenasii ICG 11558 (PI 475998) could not be infected by mechanical, aphid, and graft transmission tests, while A. chacoense ICG 4983 (PI 276235), A. cardenasii ICG 11562 (PI 476012) and ICG 12168 (PI 476013) and accessions of section Erectoides, A. sp. ICG 11560 (PI 476004) and ICG 8215 (PI 468170) and A. paraguariensis ICG 8973 (PI 468176), were infected by grafting, but not by aphid and mechanical inoculations.
