Technical Abstract: The characterization of genes that confer resistance to diseases important to sugarbeet production has been hampered by a lack of markers associated with these genes. In ongoing collaborative research, we have begun generating molecular genetic markers linked to various disease resistance genes for which segregating populations of sugarbeet have been produced. Using RAPD analysis applied to a population segregating for the Bm gene conditioning resistance to beet mosaic virus, candidate markers for this gene have been obtained. An update on the progress of using resistance gene candidates in the characterization of sugarbeet germplasm exhibiting resistance to various diseases will be presented. Emerging approaches for the study of sugarbeet genes involved in disease resistance also will be discussed
