  • 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...

  • Multiple pest suppression with cover crops in strawberry

    Creator:
    Datta, Braja Bandhu
    Abstract:
    The experiment was conducted to compare multiple pest (weed, soil arthropod and diseases) suppression by cereal cover crops in 'Selva' and 'Totem' strawberry. In addition, perlite was used to compare improvement of soil and root aeration which might modify strawberry black root rot complex. Small-seeded summer annual weeds were suppressed...

  • Evaluation of genetic diversity in wild populations of black raspberry (Rubus occidentalis L.)

    Creator:
    Dossett, Michael
    Abstract:
    In recent years, there has been renewed interest in black raspberry (Rubus occidentalis L.) breeding. This has been spurred, in part, by an increase in black raspberry consumption due to studies that have shown them to be particularly high in anthocyanin content indicating high levels of antioxidants. Present cultivars are...
