Resistance to a newly recognized pathotype of pea seed-borne mosaic virus, PSbMV-P4, was found in PI 347492, an accession of Pisum sativum from India. In cross and backcross populations between PI 347492 and the susceptible cultivars Bonneville, Ranger, and PI 269816, resistance was determined to be monogenically recessive. The symbol sbm-4 is proposed for the gene conferring resistance to this pathotype of PSbMV.
