In addition to their value as cereal grains, wheat (Triticum aestivum L.) and triticale (× Triticosecale Wittmack) are important cool-season annual forages and cover crops. Yearling steer (Bos taurus) performance was compared in the spring following autumn establishment as for age cover crops after soybean [Glycine max (L.) Merr.] grain harvest. Replicated pastures (0.4 ha) were no-till seeded in three consecutive years into soybean stubble in autumn, fertilized, and grazed the following spring near Ithaca, Nebraska, USA. Each pasture (n = 3) was continuously stocked in spring with four yearling steers (380 ± 38 kg) for …

Winter Hardy Small Cereals For Grazing Or Silage In Eastern Nebraska, Abigail Sartin
Department of Animal Science: Dissertations, Theses, and Student Research
Two, 3-year studies were conducted to evaluate the value of cereal rye, winter wheat, and winter triticale as forage sources for either for silage or early spring grazing. For silage, the objective was to evaluate species and maturity effects on dry matter yield, nutritive value, and fermentation of small cereal silage. There are no major differences between wheat, rye, or triticale in terms of the relative timing of each species reached each maturity stage. There are no differences among species in dry matter (DM) yield, except for wheat which tends to decline at soft dough due to senescence of the …
Gene Expression Changes Linked To Phenylpropanoid-Based Resistance To Fusarium Head Blight Of Wheat, Shiv Singla
Gene Expression Changes Linked To Phenylpropanoid-Based Resistance To Fusarium Head Blight Of Wheat, Shiv Singla
Department of Plant Pathology: Dissertations, Theses, and Student Research
Fusarium graminearum is a devastating pathogen of wheat that causes Fusarium head blight (FHB) and contaminates the grain with the mycotoxin deoxynivalenol (DON). Resistance to FHB is quantitative and it is important to identify additional genes conferring resistance against it. The goal of this thesis was to examine if the constitutive expression of two sorghum phenylpropanoid pathway genes, SbCCoAOMT (encoding caffeoyl-CoA O-methyltransferase) and SbC3’H (encoding p-coumarate 3-hydroxylase), in the moderately-susceptible spring wheat CB037 can provide Type-I and Type-II resistance to F. graminearum and determine the underlying mechanisms of the enhanced resistance. The constitutive expression lines (CCoAOMT413, CCoAOMT421, C3H112, …

Evaluation Of Wheat-Specific Peptide Targets For Use In The Development Of Elisa And Mass Spectrometry-Based Detection Methods, Jessica Humphrey
Department of Food Science and Technology: Dissertations, Theses, and Student Research
Individuals with IgE-mediated wheat allergy and celiac disease must avoid the consumption of wheat. Those with celiac disease must also avoid rye and barley in addition to wheat as these make up the gluten-containing grains. To ensure products are accurately labeled, ELISA methods may be used to monitor compliance with food allergen and gluten-free regulations. Currently, available ELISA methods for wheat detection utilize monoclonal antibodies that target peptides from the gluten fraction of proteins, and therefore, also detect rye and barley. Limitations such as differing antibody reactivity and unequal gluten content among wheat, rye, and barley have led to inconsistent …

Source Of Off-Type Frequencies In Winter Wheat Varieties, Michaela Benes
Source Of Off-Type Frequencies In Winter Wheat Varieties, Michaela Benes
Honors Theses
The enzyme polyphenol oxidase (PPO) is undesirable in most wheat products due to the discoloration it causes. Purifying wheat varieties through selective breeding is the best way at getting rid of PPO in a variety. The variety NW15443 was planted in both a field in McCook, NE, and in a greenhouse in Lincoln, NE. Individual heads were snapped from the field and the greenhouse seed was harvested in bulk. After completing a PPO test of the seed, it was determined that the percentages of off-type frequencies from the field seed and the greenhouse seed were 11% and 3.6%, respectively. Using …

High Plains Wheat Mosaic Virus: An Enigmatic Disease Of Wheat And Corn Causing The High Plains Disease, Satyanarayana Tatineni, Gary Hein
Department of Entomology: Faculty Publications
Brief history: In 1993, severe mosaic and necrosis symptoms were observed on corn (maize) and wheat from several Great Plains states of the USA. Based on the geographical location of infections, the disease was named High Plains disease and the causal agent was tentatively named High Plains virus. Subsequently, researchers renamed this virus as maize red stripe virus and wheat mosaic virus to represent the host and symptom phenotype of the virus. After sequencing the genome of the pathogen, the causal agent of High Plains disease was officially named as High Plains wheat mosaic virus. Hence, High Plains virus, …

Department of Political Science: Faculty Publications
The flash drought and its associated heat wave that affected western Russia in the summer of 2010 had significant cascading agricultural and socioeconomic impacts. Drought indicators sensitive to soil moisture and evapotranspiration (ET) showed that the flash drought began in June 2010, then intensified rapidly and expanded to cover much of western Russia. By early July, almost all of the major wheat producing regions of Russia were experiencing extreme water stress to the winter and spring wheat crops. The timing of the onset of the flash drought was particularly devastating as the period of most rapid intensification overlapped with the …

The Role Of Quality Characteristics In Pricing Hard Red Winter Wheat, Shane J. Roberts
The Role Of Quality Characteristics In Pricing Hard Red Winter Wheat, Shane J. Roberts
Department of Agricultural Economics: Dissertations, Theses, and Student Research
In this thesis, we empirically examine the role of conventional and end-use wheat quality characteristics on the pricing of hard red winter wheat (HRWW). We use detailed quality characteristic data as well as location matched price data for 50% and 100% harvest completion weeks and utilize a hedonic price analysis framework. We find evidence that end-use characteristics, specifically milling and baking quality characteristics, have a statistically and economically significant effect on the price of HRWW. This evidence suggests that, while HRWW producers are not directly paid premiums or discounts for end-use quality, they are paid indirectly through basis. Comparing results …

Developing A Method To Contain The Feeding Of The Wheat Curl Mite (Aceria Tosichella Keifer), Pierce Leef, Gary Hein
UCARE Research Products
To better understand the ecology and epidemiology of the wheat curl mite (Aceria tosichella Keifer) as a vector of wheat streak mosaic virus (WSMV), it is necessary to develop a method to confine the microscopic mites and their infection to specific areas of their host plants, particularly wheat and corn. In this study, corn was the plant of interest. The device developed for this mite-confining method was made by removing the lens of a phone camera lens clip and gluing a 2.5 cm x 4.5 cm piece of wood to the other arm of the clip. Clips were utilized by …
Phenology And Dispersal Of The Wheat Stem Sawfly (Hymenoptera: Cephidae) Into Winter Wheat Fields In Nebraska, Chris T. Mccullough, Gary L. Hein, Jeff Bradshaw Dr.
Phenology And Dispersal Of The Wheat Stem Sawfly (Hymenoptera: Cephidae) Into Winter Wheat Fields In Nebraska, Chris T. Mccullough, Gary L. Hein, Jeff Bradshaw Dr.
Department of Entomology: Faculty Publications
Historically, the wheat stem sawfly, Cephus cinctus Norton was a pest in spring wheat-growing regions of the northern Great Plains. However, in the 1980s, it was found infesting winter wheat fields in Montana. Infestations were first detected in western Nebraska in the 1990s, and have since spread throughout the Nebraska Panhandle. Larval damage occurs from stem-mining, but stem girdling that results in lodged stems that are not harvested results in the greatest yield losses.The biology and phenology of the wheat stem sawfly are well described in the northern portion of its range, but they are lacking in Colorado, southeast Wyoming, …

The Lateral Root Density Gene Regulates Root Growth During Water Stress In Wheat, Dante F. Placido, Jaspreet Sandhu, Shirley Sato, Natalya Nersesian, Truyen Quach, Thomas Clemente, Paul Staswick, Harkamal Walia
Department of Agronomy and Horticulture: Faculty Publications
Drought stress is the major limiting factor in agriculture. Wheat, which is the most widely grown crop in the world, is predominantly cultivated in drought-prone rainfed environments. Since roots play a critical role in water uptake, root response to water limitations is an important component for enhancing wheat adaptation. In an effort to discover novel genetic sources for improving wheat adaptation, we characterized a wheat translocation line with a chromosomal segment from Agropyron elongatum, a wild relative of wheat, which unlike common wheat maintains root growth under limited-water conditions. By exploring the root transcriptome data, we found that reduced …

Identification, Aggressiveness And Mycotoxin Production Of Fusarium Graminearum And F. Boothii Isolates Causing Fusarium Head Blight Of Wheat In Nebraska, Esteban Valverde-Bogantes
Department of Food Science and Technology: Dissertations, Theses, and Student Research
Fusarium head blight (FHB) is an economically important disease caused by several Fusarium species affecting wheat. Besides causing significant yield losses, infected grain may be contaminated with mycotoxins, primarily trichothecenes, that are harmful to both humans and animals. In recent years, reports of shifts in FHB pathogen populations in North America have highlighted the need for increased vigilance. This dissertation describes a four-year survey evaluating the species, trichothecene genotype and phenotypic diversity of FHB pathogens infecting Nebraska wheat. Most of the isolates were identified as F. graminearum (n=67). Additional species included F. boothii (n=3), F. poae (n=2) and F. acuminatum …

Effects Of Different Water And Nitrogen Regimens On Yield Of Winter Wheat Produced In Nebraska, Joseph Emory Davis
Effects Of Different Water And Nitrogen Regimens On Yield Of Winter Wheat Produced In Nebraska, Joseph Emory Davis
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Wheat is the 3rd most prominent crop in the USA and approximately 50% is exported annually. Nebraska wheat production is 11th in the country, and it plays a major role in the state's agricultural economy, especially in western NE. Generally, wheat is grown under dryland conditions and the region grows much more wheat on unirrigated land than it does on irrigated. However, deficit irrigation has shown great value in producing high yielding wheat with much less water than needed for other crops. Finding new ways to leverage irrigation in wheat production may help address the need to produce food …

Addressing The Challenges Facing Wheat Production: Nebraska And International Breeding Efforts, Sarah Blecha
Doctor of Plant Health Program: Dissertations and Student Research
Bread wheat, Triticum aestivum L., provides 20 percent of the global daily calorie intake. It is the third most important food crop, after rice and corn. Biotic challenges significantly reduce wheat yield; chemical control can be a solution but can be cost prohibitive for subsistence farmers. For many farmers, genetic resistance to biotic stresses can be the most cost effective solution.
The International Center for Agricultural Research in the Dry Areas (ICARDA) and the Nebraska Small Grains Breeding Program have been addressing these wheat production challenges. ICARDA is part of an international research consortium to increase wheat yield and tolerance …

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Rye (Secale cereale L.) chromosome arm 1RS has been used world-wide by wheat (Triticum aestivum L.) breeding programs as a source of pestand pathogen-resistance genes, and to improve grain yield and stress tolerance. The most common vehicles used to access 1RS are various 1AL.1RS and 1BL.1RS wheat-rye chromosomal translocations. Over the past 25 years, advanced North American wheat breeding lines were evaluated, first by assay of secalin storage proteins, and later by use of DNA marker TSM0120, for the presence of these two translocations. Both methods provide accurate and efficient means of identifying and differentiating 1BL.1RS and 1A.1RS. Both 1Al.1RS …

Fusarium head blight (FHB) is among the most common fungal diseases affecting wheat, resulting in decreased yield, low-density kernels, and production of the mycotoxin deoxynivalenol, a compound toxic to humans and livestock. Human visual analysis of representative wheat samples has been the traditional method for FHB assessment in both official inspection and plant breeding operations. While not requiring specialized equipment, visual analysis is dependent on a trained and consistent workforce, such that in the absence of these aspects, biases may arise among inspectors and evaluation dates. This research was intended to avoid such pitfalls by using longer wavelength radiation than …
