  • 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...

  • Isozyme variation and inheritance in hazelnut

    Creator:
    Cheng, Suozhan
    Abstract:
    Inheritance of eight enzyme systems, alanine aminopeptidase (AAP), aspartate aminotransferase (AAT), aconitase (ACON), glucose phosphate isomerase (GPI), malate dehydrogenase (MDH), 6-phosphogluconate dehydrogenase (6-PGD), phosphoglucomutase (PGM), and shikimate dehydrogenase (SDH) was studied in hazelnut (Corylus avellana L.) by either polyacrylamide gel electrophoresis (PAGE) or starch gel electrophoresis. Three isozymes were detected...

  • 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...

  • 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...

  • 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...

  • Estimation of genetic-parameters in the Oregon State University Hazelnut (Corylus avellana L.) breeding population

    Creator:
    Yao, Qiang
    Abstract:
    Heritability in the narrow sense and in the broad sense, variance components and correlation coefficients are important genetic parameters in a breeding program. The estimates of these parameters can provide important information for a breeder in the selection of parents, the most efficient design for evaluation of seedlings and advanced...

  • A linear equation model for a family of interconnection networks

    Creator:
    Larson, Shawn M.
    Abstract:
    The most important part of parallel computation is communication. Except in the most embarassingly parallel examples, processors cannot work cooperatively to solve a problem unless they can communicate. One way to solve the problem of communication is to use an interconnection network. Processors are located at nodes of the network,...

  • Isokinetic muscular strength and endurance of active men over age 50 using different training protocols

    Creator:
    Jordan, Shawn D.
    Abstract:
    The purpose of this study was to compare the muscular strength and endurance of thirty-two men 51 to 79 years of age who engage in weight training (WT), aerobic training (AT), cross training (CT), or no training (S). The design employed in the study was a 2x2 between subjects factorial...
