Inheritance of Beet Mosaic Virus Resistance in Sugarbeet. R. T. Lewellen, Research Geneticist, ARS, USDA, U.S. Agricultural Research Station, Salinas, California 93901; Phytopathology 63:877-881. Accepted for publication 18 January 1973. DOI: 10.1094/Phyto-63-877.

An annual line of sugarbeet (Beta vulgaris) was shown to be a source of beet mosaic virus (BMV) resistance. Inheritance studies indicated that one incompletely dominant gene, Bm, conditioned resistance. Local lesion counts on Chenopodium amaranticolor from BMV-infected sugarbeet sources showed that the concentration of virus was reduced by the Bm gene and that the heterozygous F1 was intermediate in concentration. Bm was specific against all isolates of BMV tested, but appeared to have no modifying effect on systemic infection by other beet viruses.
