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...

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...

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...

Facilitating plant-parasitic nematode management decisions for Washington Vitis vinifera growers : determining the spatial distribution of plant-parasitic nematodes and the host status of Vitis spp. to Meloidogyne hapla

Creator:: Howland, Amanda D.
Abstract:: A major constraint to the production of self-rooted wine grapes (Vitis vinifera) in eastern Washington is plant-parasitic nematodes. Plant-parasitic nematodes can impact grape productivity by limiting water and nutrient uptake, educing physiological changes, and extracting plant nutrients from roots, thereby reducing root biomass, plant vigor, and yield. The most commonly...

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...

On-farm inquiry and assessment of tillage and cover cropping for white mold control in snap bean production

Creator:: Harrison, Elizabeth Langham.
Abstract:: Cultural practices in snap bean production were evaluated at the Oregon State University Vegetable Research Farm Corvallis, Oregon. In addition, decision-making in snap bean production was assessed on five farms in the Coburg-Junction City-Harrisburg regions of the Willamette Valley, Oregon. A field experiment with cover crop and tillage techniques was...

Plant hormone-induced defense responses against Botrytis cinerea

Creator:: Akagi, Aya
Abstract:: Several plant hormones, including ethylene and jasmonates, are known to mediate responses against biotic and abiotic stress. The first and second objectives of this thesis were (i) to elucidate the role of ethylene in defense responses against Botrytis cinerea and specifically (ii) to determine the potential contribution of ethylene response...

Detection, identification, and antibiotic treatments of bacterial contaminants from micropropagated strawberries

Creator:: Tanprasert, Piyarak
Abstract:: Bacterial contamination is one of the most important problems both in plant tissue culture research and commercial laboratories. Early detection of contaminants saves time, effort, and money. Strawberry runner explants were screened for contaminants during June to August, 1994 and 1995. Most contaminants found were bacterial rather than fungal. Bacterial...

Phenology, Host-Plant Resistance, and Biological Control of Stephanitis pyrioides in Oregon

Creator:: Flores, Salvador M.
Abstract:: The azalea lace bug (Stephanitis pyrioides Scott) is a recently detected invasive pest to the Pacific Northwest and has become a major concern in Oregon. It feeds on azaleas as well as rhododendrons causing stippling on the top side of leaves. The damage is aesthetically displeasing and affects plant vigor...
