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 ... -
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 ... -
Genetics of Drought Tolerance in Hard Red Spring Wheat in the Northern United States of America
(North Dakota State University, 2017)Drought affects about 50% of wheat (Triticum aestivum L.) globally and is a major threat for sustainable wheat production. This dissertation discusses three studies carried out to dissect drought tolerance in hard red ... -
Genetics of End-Use Quality Characteristics in Spring Wheat (Triticum Aestivum L.)
(North Dakota State University, 2017)Wheat (Triticum aestivum L.) is one of the most important crops consumed by humans around the world. Improving the end-use quality traits is one of the major objectives in wheat breeding programs. However, little is known ... -
Glycoalkaloid Profiling of Potato Genotypes from the North Dakota State University Potato Breeding Program
(North Dakota State University, 2013)Gylcoalkaloids (GA) are plant secondary metabolites that offer pests and disease resistance. Studies show correlation between GA content and CPB resistance. In this study, CPB resistance was assessed in a field trial at ... -
Identification and Genomic Analysis of Stagonospora Nodorum Blotch Susceptibility Genes in Wheat
(North Dakota State University, 2014)Parastagonospora nodorum is a necrotrophic fungal pathogen that causes the disease Stagonospora nodorum blotch (SNB) on wheat. The fungus produces necrotrophic effectors (NEs), that when recognized by corresponding host ... -
Identification and Validation of a New Source of Low Grain Cadmium Accumulation in Durum Wheat (Triticum Turgidum L. Subsp. Durum (Defs.))
(North Dakota State University, 2017)Cadmium (Cd) is a toxic heavy metal with no known biological function. The maximum level of Cd concentration allowed in the international market for wheat grain is 0.2 mg kg-1. Higher Cd levels in durum wheat (Triticum ... -
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 ... -
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 ... -
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 ... -
Marker Assisted Selection Increases the Efficiency of Breeding for Potato Virus Y Resistance in Potato
(North Dakota State University, 2014)Potato Virus Y (PVY) is an important virus of potato due to the non-persistent mode of transmission by aphids causing yield losses. Genetic resistance is the recommended control since insecticides cannot adequately control ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
