Anisogramma anomala causes a stem canker of filberts, Corylus avellana. This disease became a threat to the main U.S. filbert growing region when it was introduced into the Pacific Northwest around 1968. Various methods of artificially inoculating filbert trees and seeds were explored. Less than 1% of potted filbert trees...

European Hazelnut (Corylus avellana L.) is an important crop in the Pacific Northwest where around 5% of the world's hazelnuts are produced. Hazelnut production in the Pacific Northwest is threatened by eastern filbert blight (EFB) caused by the pyrenomycete Anisogramma anomala. Host resistance is a useful strategy to control disease,...
To identify novel host genetic resistance to eastern filbert blight, caused by the fungus Anisogramma anomala (Peck) E. Muller, ninety European hazelnut {Corylus avellana L.) varieties and interspecific hybrids (with C. americana Marsh, or C. colurna L.) were screened for response to the eastern filbert blight pathogen after inoculation in...
European hazelnut, an important nut crop in Oregon agriculture, is threatened by the fungal disease eastern filbert blight (EFB) caused by Anisogramma anomala (Peck) E. Müller. The hazelnut breeding program at OSU has been working on development of EFB-resistant cultivars. DNA markers allow mapping of traits using segregating progenies and...
The heritability of resistance to eastern filbert blight, caused by Anisogramma anomala, in European hazelnut (Corylus avellana) was evaluated in the progeny of seven cultivars crossed in 12 combinations. Progeny produced by crossing 'VR6-28' with three susceptible cultivars segregated 1:1 for complete resistance to eastern filbert blight. Histograms of disease...
