Boerma and Kuhn (1976) established that 'Dorman' and 'CNS' each contain a single dominant gene conditioning resistance to peanut mottle virus (PMV). The gene was labelled Rpv, but it was not demonstrated that the genes in the cultivars were allelic. Shipe et al. (1979) also demonstrated the presence of single dominant genes for PMV resistance in each of 'Arksoy', 'PI 89784' and 'PI 219789', but made no tests for allelic relationships.
