Red Clover Clones with Hypersensitive Reaction to an Isolate of Bean Yellow Mosaic Virus. Stephen Diachun and Lawrence Henson, Department of Plant Pathology, University of Kentucky, Lexington 40506 Phytopathology 64:161-162.

Clones of red clover resistant to bean yellow mosaic virus, cause of a major disease of red clover, have been selected as potentially useful breeding lines for development of red clover cultivars.  The clones are first-generation inbreds of a plant in which hypersensitive primary lesions result in localization of the virus.  Resistance is controlled by a single dominant factor that is present in a homozygous condition in these clones.
