Genetic Characterization of Dormancy in Durum Wheat
(North Dakota State University, 2012)Two populations derived by crossing LDN x LDN Dic-3A (Population I) and LDN x LDN Dic-3B (Population II) were genetically characterized for the seed dormancy present on chromosome 3A and 3B of durum wheat. The genes for ... -
Developing a DNA Fingerprint for Midwest Six-rowed Malting Barley
(North Dakota State University, 2012)The requirements for brewing beer from barley (Hordeum vulgare L.) malt are specific and unique for each brewer. Anheuser-Busch InBev and Miller Coors Brewing Company (MillerCoors) are two major brewers in the United States ... -
Comparative Population Genetics of Fusarium Graminearum and Novel Sources of Resistance to Fusarium Head Blight in Spring Wheat
(North Dakota State University, 2013)Fusarium graminearum is the major causal agent of Fusarium head blight (FHB) in cereal crops. The fungus produces several types of trichothecenes [Deoxynivalenol (DON) and its acetylated derivatives, 3-acetyldeoxynivalenol ... -
Genetic and Physiological Relationships between Oat Grain Quality Components
(North Dakota State University, 2013)The use of oats for human consumption is increasing every day due to the health benefits of oat products. With the objective to study relationships among factors affecting oat grain quality, two Recombinant Inbred Lines ... -
Identification of Quantitative Trait Loci Associated with a Low Cadmium Uptake Gene in Durum Wheat (Triticum Turgidum L. Var. Durum)
(North Dakota State University, 2013)The main objective of durum wheat breeding is to identify lines that are low in Cadmium accumulation by using linkage mapping. 178 recombinant inbred lines (RILs) derived from across between Grenora × Haurani were used to ... -
Development and Characterization of Wheat Germplasm for Resistance to Stem Rust UG99 in Wheat
(North Dakota State University, 2013)World wheat production is currently threated by stem rust (caused by Puccinia graminis f. sp. tritici) Ug99 race (TTKSK). The ongoing global effort to combat Ug99 is focusing on the identification and deployment of ... -
Total Yellow Pigment Content and Oxidative Stress Level during Kernel Development
(North Dakota State University, 2013)The focus of this research was to determine the effects of cultivar and environment on levels of total yellow pigment content and oxidative stress during grain development and in semolina and pasta. Lipoxygenase activity ... -
Unraveling the Genetics of Seed Dormancy in Barley Using Genome-Wide Association and Biparental Mapping
(North Dakota State University, 2013)Seed dormancy is the delay or inability of viable seeds to germinate under favorable conditions. The differential expression of dormancy levels in barley (Hordeum vulgare L.) seeds impacts malt quality. While dormant ... -
QTL Analysis for Fusarium Head Blight Resistance in Tunisian-Derived Durum Wheat Populations
(North Dakota State University, 2014)Durum (2n=4x=28; AABB) wheat is the grain of choice for the production of high-quality pasta products. Fusarium spp. are causal pathogens for Fusarium Head Blight (FHB). Limited host resistance to this disease exists among ... -
Uncovering the Genetic Basis and Characters Association of Wheat Spike-Related, Agronomic and Quality Traits
(North Dakota State University, 2014)Modern wheat (Triticum aestivum L.) cultivars are characterized by having spikes with fusiform architecture and rachis nodes with one spikelet. However, genotypes with supernumerary spikelets (SS) in which rachis nodes ... -
Quantitative Genetics of Drought Resistance in Early Maturing Maize (Zea Mays L)
(North Dakota State University, 2015)Drought stress is paramount in limiting worldwide maize (Zea mays L.) production and productivity. In addition, drought has limited expansion of maize production to marginal conditions in areas including western North ... -
Identification of Molecular Markers for Marker-Assisted Selection of Malting Quality and Associated Traits in Barley
(North Dakota State University, 2015)Barley (Hordeum vulgare L.) is one of the most important cereal crops in North Dakota, which ranks second amongst all states for barley production in the United States. Barley is used for the production of malt, which is ... -
Genetic Diversity and Genome-Wide Association Mapping of Agronomic, Disease Resistance, and Quality Traits in Barley Accessions from Ethiopia, Icarda, and the U.S.
(North Dakota State University, 2015)Plant breeding is a dynamic process that incorporates new germplasm to introduce genetic variation. Knowledge gained from genetic diversity studies and identification of potentially useful germplasm is critical for efficiently ... -
Molecular Mapping of Fusarium Head Blight Resistance in Two Adapted Spring Wheat Cultivars
(North Dakota State University, 2015)Releasing bread wheat (Triticum aestivum) cultivars with resistance to Fusarium head blight (FHB) disease can be endangered by narrowing the variation in genetic sources. However, resistance to FHB rely on five different ... -
Genomic Mapping of Leaf Rust and Stem Rust Resistance Loci in Durum Wheat and Use of RAD-Genotype by Sequencing for the Study of Population Genetics in Puccinia Titicina
(North Dakota State University, 2016)Leaf rust, caused by Puccinia triticina Erikss. (Pt), and stem rust, caused by Puccinia graminis f. sp. tritici Erikss. and E. Henn (Pgt), are among the most devastating diseases of durum wheat (Triticum turgidum L. var. ... -
Identifying Dry Bean Genotypes and Genomic Regions Associated with Root Rot Resistance with Emphasis on Fusarium Solani F. Sp Phaseoli
(North Dakota State University, 2016)Common bean (Phaseolus vulgaris L.) is the most produced legume in the U.S. and worldwide. Fusarium root rot (FRR) is a widespread soil-borne diseases causing up to 86% yield reduction in beans. Large-seeded cultivars are ... -
