  • Inheritance of resistance to Fusarium root rot in Phaseolus vulgaris L., and Phaseolus coccineus L.

    Creator:
    Azzam, Hassan Ahmed
    Abstract:
    Progenies of two bean crosses were studied for inheritance of resistance to dry root rot caused by Fusarium solani f. phaseoli. O.S.C. 22 (P. vulgaris) was used in both crosses as the susceptible parent. A Mexican line (P. vulgaris) and a line 2014 of the runner bean (P. coccineus) were...

    Darby, Heather
    Abstract:
    Annual applications of fresh or composted dairy manure were assessed for their effects on root rots of sweet corn and snap bean and damping-off of cucumber in a field soil. Soil biological and physical properties were measured as possible indicators of root rot suppressive potential. Regardless of amendment type or...

  • Serial manure amendments : effects on soil properties and root rot of sweet corn

    Creator:
    Cox, Bonnie S. Hoffman
    Abstract:
    The effect of serial (multiple-year) organic matter (OM) amendment on soil properties has been described in some cropping systems, although less is known about the effect of serially amended field soils on soil-borne plant diseases. The objectives of this study were to describe the effects of the third and fourth...

  • Investigating the Genetic Control of Fusarium Root Rot Resistance in Snap Beans

    Creator:
    Huster, Abigail R.
    Abstract:
    Root rot diseases are a major constraint to bean (Phaseolus vulgaris L.) production around the world. Both snap beans and dry beans are affected. Root rot diseases can be caused by a variety of pathogens; however, Fusarium solani is a common causal agent. Fusarium root rot is a primary yield...

  • Mapping QTL for root rot resistance, root traits, and morphological trait in a common bean recombinant inbred population

    Creator:
    Hagerty, Christina H.
    Abstract:
    Root rot diseases of bean (Phaseolus vulgaris L.) are a problem wherever they are grown, and are a major constraint to dry edible and snap bean production. Root rot is a primary yield limitation of snap bean production in the US, especially within the top three snap bean producing states...

  • Cover crop effects on root rot of sweet corn and soil properties

    Creator:
    Miyazoe, Mikio
    Abstract:
    Root rot of sweet corn in western Oregon and Washington is a significant disease that can reduce yield of intolerant cultivars of processed sweet corn by fifty percent. Root rot is caused by a complex of soilborne organisms, including Drechslera sp., Phoma terrestris, and Pythium arrhenomanes. Processors have adopted tolerant...
