Genome-Wide Association Mapping of Host Resistance to Stem Rust, Leaf Rust, Tan Spot, and Septoria Nodorum Blotch in Cultivated Emmer Wheat
(North Dakota State University, 2015)Cultivated emmer wheat (Triticum turgidum ssp. dicoccum) is a good source of genes for resistance to several major diseases of wheat. The objectives of this study were to use genome-wide association analysis to detect ... -
Unraveling the Genetic Architecture of Agronomic Traits and Developing a Genome Wide InDel Panel in Common Bean (Phaseolus vulgaris)
(North Dakota State University, 2015)Common bean (Phaseolus vulgaris) is an economically important legume. The agronomic characteristics of this crop such as days to flower, growth habit and seed yield affect breeding strategies. However, little is known about ... -
Glandular Trichome Evaluation through Scanning Electron Microscopy and the Modified Enzymic Browning Assay
(North Dakota State University, 2015)Potato (Solanum tuberosum L.) ranks fifth in the USA in comparison with other countries regarding potato production. Colorado potato beetle (Leptinotarsa decemlineata Say) is a devastating insect pest affecting potato in ... -
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 ... -
Adaptation of Quality Protein Maize (Zea Mays L.) to Northern U.S. Corn Belt
(North Dakota State University, 2015)There is a need to increase the value of crops and develop the next generation of healthier products. Quality protein maize (Zea mays L.) is an option but has never been adapted to short – season environments. Quality ... -
Cloning and Characterization of the Iron-Regulated Transporter (IRT) Genes and Their Transcription Factors in Populus
(North Dakota State University, 2015)Iron deficiency causes chlorosis in many plant species, resulting in yield loss and poor quality. Many tree species including poplar are susceptible to iron deficiency. Trees suffering from iron deficiency often show ... -
Genetic and Environmental Variation on Mineral Nutrient Concentration in Pea and Lentil Seed
(North Dakota State University, 2015)Current food supply is expected to be insufficient to support the growing population both in quantity and nutritional quality; therefore, the need to breed for higher yield and greater nutritional quality is urgent. ... -
Homoeology of Thinopyrum Junceum and Elymus Rectisetus Chromosomes to Wheat and Disease Resistance Conferred by the Thinopyrum and Elymus Chromosome in Wheat
(North Dakota State University, 2015)Thirteen common wheat ‘Chinese Spring’ (CS)-Thinopyrum junceum addition lines and three common wheat ‘Fukuhokomuji’(Fuku)-Elymus rectisetus addition lines were characterized and verified as disomic additions of a Th. junceum ... -
Efficacy of Current Maize BT Traits Against Corn Rootworms in North Dakota
(North Dakota State University, 2015)Field experiments were conducted to determine the efficacy of current Bt traits in maize (Zea mays L.) hybrids and soil-applied insecticide for corn rootworm (Diabrotica spp.) management. Experiments were conducted as a ... -
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 and Genetic Characterization of Fusarium Head Blight Resistance in Durum Wheat
(North Dakota State University, 2015)Fusarium head blight (FHB) is a devastating fungal disease of both durum and common wheat. Multiple sources of FHB resistance have been found in common wheat, but not in durum wheat. Lack of effective FHB resistance sources ... -
Nitrogen Effects on Low-Protein and Semidwarf Genotypes for Malting Barley Production in Western North Dakota
(North Dakota State University, 2015)Producing barley that meets the quality specifications set by the malting and brewing industry can be difficult in western North Dakota growing conditions. Semidwarf and low protein genotypes may help producers of malting ... -
Nitrogen Management in Dry Bean and Soybean
(North Dakota State University, 2015)Legume crops, dry bean (Phaseolus vulgaris L.) and soybean (Glycine max (L.) Merr.), can form symbiotic relationships with nitrogen-fixing bacteria. Nitrogen (N) fertilizer may be necessary for optimal yields. Three ... -
Roles of the TSN1 and TSC2 Genes in Conferring Susceptibility of Durum Wheat to Tan Spot and Septoria Nodorum Blotch
(North Dakota State University, 2015)Tan spot is an important disease caused by the necrotrophic fungus Pyrenophora triticirepentis. Two common necrotrophic effectors produced by this fungus are Ptr ToxA and Ptr ToxB, which recognize host sensitivity genes ... -
Advanced Cropping Systems for Oil and Biomass Feedstock Production in the Northern Great Plains

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 ... -
The Acquisition of Useful Disease Resistance Genes for Hard Red Winter Wheat Improvement
