Investigation of novel sources of genetic resistance to eastern filbert blight

Creator:: Lunde, China F.
Abstract:: 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...

DNA markers linked to novel sources of resistance to eastern filbert blight in European hazelnut (Corylus avellana L.)

Creator:: Sathuvalli, Vidyasagar R.
Abstract:: The hundred-year history of the hazelnut industry in the Pacific Northwest is threatened by eastern filbert blight (EFB) caused by the fungus Anisogramma anomala (Peck) E. Müller. Marker-assisted selection (MAS) has been extensively used for ‘Gasaway’ resistance in the hazelnut breeding program at Oregon State University. Concern over breakdown of...

Fine Mapping and Gene Expression Analysis of Self-Incompatibility in Hazelnut

Creator:: Hill, Ryan J.
Abstract:: The European hazelnut (Corylus avellana L.) is a diploid (2n = 2x = 22) tree crop important to the economy of Oregon’s Willamette Valley, where 99% of hazelnut production in the United States is located. Corylus avellana exhibits sporophytic self-incompatibility (SSI), controlled by a single S-locus with at least 33...

Genetic resistance to eastern filbert blight

Creator:: Coyne, Clarice Jean
Abstract:: Eastern filbert blight, caused by Anisogramma anomala (Peck) E. Muller, is a serious threat to hazelnut (Corylus avellana L.) production. Resistant cultivars offer the best control. Screening systems were needed to reliably identify disease, particularly in immune progeny derived from 'Gasaway'. An indirect enzyme-linked immunosorbant assay (ELISA) was developed using...

The evaluation of cold hardiness in Corylus

Creator:: Chozinski, Annie M.
Abstract:: Anthesis of both staminate and pistillate flowers of Corylus occurs in midwinter. To insure adequate pollination and nut set, these flowers must attain a sufficient hardiness level to withstand low temperatures. This study estimated cold hardiness of Corylus cultivars and species using laboratory freezing of shoots without artificial hardening. In...

New sources and linked AFLP markers for Eastern filbert blight resistance in hazelnut

Creator:: Chen, Honglin
Abstract:: Eastern filbert blight (EFB), caused by Anisogramma anomala (Peck) E. Miiller, is a devastating disease to orchards of the European hazelnut (Corylus avellana L.) in the Willamette Valley, Oregon. Host resistance is the most desirable means of disease control. Fifty-eight hazelnut accessions, including European cultivars and interspecific hybrids were evaluated...

Identification and development of PCR-based markers linked to eastern filbert blight resistance in hazelnut

Creator:: Davis, Joel W.
Abstract:: Using bulked segregant analysis, five RAPD markers were identified that were linked in coupling to a gene conferring complete resistance to eastern filbert blight caused by Anisogramma anomala (Peck) E. Muller in hazelnut (Corylus avellana L.). Two modified backcross populations were inoculated and scored for resistance to the pathogen and...

Eastern filbert blight in hazelnut (Corylus avellana): identification of new resistance sources and high resolution genetic and physical mapping of a resistance gene

Creator:: Sathuvalli, Vidyasagar R.
Abstract:: European hazelnut, Corylus avellana L., is the only economically important nut crop in the family Betulaceae. One of the threats to the hazelnut industry in the Pacific Northwest is the fungal disease eastern filbert blight (EFB) caused by the pyrenomycete Anisogramma anomala. Host genetic resistance to EFB identified in the...

Characterization of European hazelnut (Corylus avellana) cultivars using SSR markers

Creator:: Gokirmak, Tufan
Abstract:: Twenty-one pairs of simple sequence repeat (SSR) primers were used to investigate genetic diversity in 270 accessions of European hazelnut (Corylus avellana) representing a wide geographic range. A capillary electrophoresis system and ABI Genescan® and Genotyper® software were used to determine the allele size generated from each PCR reaction based...
