Developing a hemp dihaploid protocol

Creator:: Murphy, Sean K.
Abstract:: Cannabis production has gained popularity over the last 10 years. There is a growing demand for true-to-type grain, fiber, and resin crops. Breeding for homozygous trait development with traditional methods can take as long as 8 years. With dihaploid breeding, homozygosity can be achieved in 2 generations saving breeders time...

Aluminum Tolerance of Winter Wheat

Creator:: Sadler, Cameron
Abstract:: Wheat is an important part of a healthy and balanced diet, requiring six servings per day to maintain a recommended 2000 Calorie intake (McRae, 2017). Because of this more land than almost any other kind of cereal is set aside for the purposes of growing wheat. To keep up with...

Inducing and Evaluating Phenotypic and Cytometric Variation in Landscape Plants : Observations from Acer, Ornithogalum, and Penstemon

Creator:: Lattier, Kim Shearer
Abstract:: Hereditary variation is a vital component in the development of new and improved cultivars of landscape plants. Sources of hereditary variation include naturally occurring variation, recombination due to controlled crosses, artificial mutagenesis, and genetic modification via biotechnology. Here I explore all methods with the exception of genetic modification via biotechnology....

Differential Effects of First Year Wheat Genotype on the Suppression of Take-All Disease and the Establishment of Suppressive Microbial Agents in the Rhizosphere

Creator:: Perkins, Evan M.
Abstract:: Recent research in the UK has found that the wheat cultivar grown in the first year can have a significant impact on the amount of take-all that develops in the second year, regardless of the cultivar planted in year two. ‘Einstein’ is one such cultivar that reduces take-all disease (reduced...

Developing Tools for Hardy Hibiscus and Lilac Breeding: Quantile Regression, Cytogenetics, Interspecific Hybridization, Somatic Hybridization, and Marker-Trait Association

Creator:: Chen, Hsuan
Abstract:: Hibiscus and lilacs (Syringa spp.) are economically important nursery crops in the US that accounted for 4.5 million units ($30 million) and 2 million units ($20 million), respectively (USDA, 2016). To maintain and expand the market share of ornamental plants such as lilacs and Hibiscus, novel performance, floral ornamental value,...

Impact of Preharvest Weathering, Without Sprouting, on the Quality of Soft White Winter Wheat in the U.S. Pacific Northwest

Creator:: Smith, Jordan L.
Abstract:: When wheat is exposed to rain in the period before harvest, it sometimes causes the problem of pre-harvest sprouting (PHS). Wheat that undergoes sprouting has poor end-use quality and is less valuable. In recent years, the U. S. Pacific Northwest (PNW) has experienced increased summer showers sometimes causing widespread PHS....

The influence of hop drying parameters on aroma hop quality in American deep bed drying

Creator:: Rubottom, Lindsey N.
Abstract:: American hop growers have historically dried hops in the range of 140-155°F/ 60-68°C using deep bed kilns (24 – 32 inches/ 60 – 81 cm), but over the last 10 years they have shifted to lower temperatures (125 -135 °F/ 52 – 57°C) for drying new American aroma cultivars. Reduced...

Estimating Lime Requirement for Oregon Soils with Non-Hazardous Soil Test Methods

Creator:: Makepeace, Carl A.
Abstract:: Various soil tests are routinely used in the United States to predict soil lime requirement. New non-hazardous methods have recently been proposed for adoption in Oregon, however the accuracy of these methods for Oregon soils has not been established. The objectives of this investigation were: (a) to document and describe...

Quantitative Trait Loci and Genome Wide Association Study for Resistance to White Mold in Common (Snap) Bean.

Creator:: Arkwazee, Haidar A.
Abstract:: This is a Ph.D. dissertation for a study conducted at OSU/Horticulture. The main objective of this study was dissecting the genetic background for white mold resistance in common (snap) bean. Tow main approaches were followed to achieve the goal. The first approach was using the classical quantitative trait loci (QTL)...

Influence of Soft Wheat Characteristics on Quality of Batter-based Products

Creator:: Fajardo Centeno, Carlos A.
Abstract:: Wheat is a globally traded staple crop. Wheat is important in human diets because of its agronomic adaptability, physical characteristics, functionality for the production of leavened products and nutritional value. Two significant characteristics make wheat an important staple food-crop. First, the proteins present in wheat endosperm have attributes that enable...
