Abstract
The barley (Hordeum vulgare) accession Cebada Capa has been used extensively as a source of resistance to the leaf rust pathogen (Puccinia hordei) in the Virginia barley breeding program, Cebada Capa possesses the resistance gene Rph7; and in the mid-Atlantic region of the United States, cultivars derived from it have remained resistant to P. hordei since 1968. In 1990, outbreaks of leaf rust were observed in Virginia on cultivars carrying Rph7. Isolates of P. hordei collected from these cultivars were found to possess virulence on Cebada Capa in greenhouse and growth chamber experiments. In addition to Virginia, P. hordei isolates with Rph7 virulence were identified in Pennsylvania and California
