Introgression and Evaluation of Wheat (Triticum aestivum L.) Conferring Resistance to Quizalofop-p-ethyl Herbicide

Creator:: Richter, Colette M.
Abstract:: Wheat (Triticum aestivum L.) is one of the most important crops in the world supplying about 18.8 percent of the world's caloric energy supply and 20 percent of the world's protein. In the Pacific Northwest (PNW), over one million hectares of wheat are grown every year. Wheat production is typically...

Kernel hardness, protein, and viscosity as predictors of udon-noodle quality

Creator:: Ruddenklau, Helle G.
Abstract:: The Asian noodle market is responsible for the increased volume of wheat imported to that region in recent years. Soft white wheat produced in the Pacific Northwest is mainly used for baked products, whereas an Australian wheat, Australian Standard White, is preferred for noodles. To enter this market soft white-wheat...

Impact of weak and strong acids on the destruction of lactic acid bacteria during high pressure processing

Creator:: Sarangapani, Rama Krishna
Abstract:: High hydrostatic pressure (HHP) affects the pH of weak acids due to an increased degree of acid dissociation while under pressure. The temporary pH reduction by high pressure in such a case may influence the barotolerance of microorganisms. The objective of this study was to determine the impact of weak...

Overwintering survival of stem rust on perennial ryegrass : construction of a simulation model, and effects of the mycoparasite Sphaerellopisis filum

Creator:: Gordon, Tyler C.
Abstract:: Stem rust, caused by the fungus Puccinia graminis subsp. graminicola, can cause yield reductions exceeding 90% on perennial ryegrass (Lolium perenne L.) crops grown for seed if not treated with fungicide in the spring. There is evidence that late-spring stem rust epidemics are initiated by populations that survived the winter....

Hybridization between imidazolinone-resistant wheat (Triticum aestivum L.) and jointed goatgrass (Aegilops cylindrical Host.) and selection pressure impacts on proportion of resistance alleles

Creator:: Martins, Bianca Asssis Barbosa
Abstract:: Imazamox-resistant wheat (Clearfield®) cultivars carry the Imi1 gene, which confers resistance to the imidazolinone (IMI) herbicide imazamox. Imazamox provides selective control of jointed goatgrass and other weeds in IMI-resistant wheat. Imi1 gene flow between IMI-resistant wheat and jointed goatgrass may occur via hybridization and backcross events. In 2009 and 2010,...

Phylogeography and Evolution of Effector Genes in Phytophthora Species

Creator:: Shakya, Shankar K.
Abstract:: Plant pathogens in the genus Phytophthora are known to cause disease on field crops, nursery plants, and forest trees. The best known example probably is Phytophthora infestans, which triggered the infamous Irish potato famine. Other important Phytophthora species include: P. ramorum (sudden oak death pathogen), P. sojae (soybean root rot...

Investigation of hop downy mildew through association mapping and observations of the oospore

Creator:: Parker, Thomas B.
Abstract:: Hop downy mildew is a devastating disease affecting hop requiring expensive fungicide applications throughout the growing season. Plant resistance is highly desirable and theorized as being decidedly quantitative with dominance and epistasis involved in resistance. An association mapping approach using a mixed-model was used to identify AFLP markers associated with...

Sea urchin-kelp forest communities in marine reserves and areas of exploitation : community interactions, populations, and metapopulation analyses

Creator:: Moctezuma, Gabriela Montaño
Abstract:: Marine ecosystems can be exposed to natural and anthropogenic disturbances that can lead to ecological failures. Marine reserves have been lately suggested to protect marine populations and communities that have been affected by habitat destruction and harvest. This research evaluates the potential role of two marine reserves established in Oregon...

High-density Linkage Maps for European Hazelnut (Corylus avellana L.) from Single Nucleotide Polymorphism Markers and Mapping New Sources of Resistance to Eastern Filbert Blight

Creator:: Komaei Koma, Golnaz
Abstract:: European hazelnut (Corylus avellana L.) is a diploid with 11 pairs of chromosomes (2n = 2x = 22), monoecious, dichogamous and wind-pollinated. Eastern filbert blight (EFB) caused by Anisogramma anomala is a serious disease of European hazelnut (Corylus avellana) in North America, and infection leads to cankers that girdle branches...

Effect of nitrogen and water stresses during tillering and grain- filling in wheat

Creator:: Ashraf, Muhammad, 1952-
Abstract:: The CERES-Wheat Crop Growth and Development model treats temperature, nitrogen and water stresses as limiting factors. For each day the model calculates a stress index for temperature, N and water, compares the magnitude of the indices, and then adjusts the calculated daily potential growth using the index of the most...
