Genetics and Quantitative Trait Loci Mapping of Septoria Tritici Blotch Resistance, Agronomic, and Quality Traits in Wheat
(North Dakota State University, 2013)Most breeding programs aim at developing superior germplasm and better cultivars that combine high yield, disease and pest resistance, and end-use quality to satisfy the requirements of the growers as well as industry. A ... -
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 ... -
Genetics of the Host-Pathogen Interaction in the Barley-Net Form Net Blotch System
(North Dakota State University, 2017)Pyrenophora teres f. teres is a fungal pathogen that causes barley net form net blotch. To evaluate the genetics of resistance in barley, a RIL population was developed using resistant barley lines CI5791 and Tifang and ... -
Genetics of Wheat Domestication and Septoria Nodorum Blotch Susceptibility in Wheat
(North Dakota State University, 2019)T. aestivum ssp. spelta Iranian type has long been thought to potentially be the direct non-free threshing hexaploid progenitor. I evaluated a RIL population derived from a cross between CS and Iranian spelta accession ... -
Genome Mapping and Molecular Markers for Ascochyta Blight Resistance in Pea (Pisum Sativum L.)
(North Dakota State University, 2012)Ascochyta blight is the most common disease of economic importance in peas (Pisum sativum L.) in North Dakota. Selection based on molecular markers would greatly facilitate identification of resistant varieties. A mapping ... -
Genome Wide Association Study of Basic Fruit Chemistry in the Cold Climate Wine Grapes (Vitis spp.)
(North Dakota State University, 2022)To overcome some of these challenges posed by ND climate, the utilization of native wild Vitis-derived varieties is the best possible option available. Despite advantageous environmental tolerances of native wild Vitis ... -
Genome-Wide Association Mapping and Genomic Prediction for Resistance to Sclerotinia Stem Rot in Rapeseed/Canola (Brassica napus L.) Germplasm Collections
(North Dakota State University, 2021)Sclerotinia stem rot (SSR), caused by Sclerotinia sclerotiorum, is a devastating disease of rapeseed/canola that causes significant seed yield loss, reduced oil content, and quality. Lack of complete immune genotypes and ... -
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 ... -
Genome-wide Association Study and Genomic Prediction for Pod Shatter Resistance in Brassica napus L.
(North Dakota State University, 2022)The release of seeds from a mature dry pod is known as shattering. Pod shattering results in significant yield losses in rapeseed/canola. An experiment was conducted in five environments in 2020 and 2021 under the field ... -
Genome-Wide Association Study of Heat Tolerance in Rapeseed/Canola (Brassica Napus L.)
(North Dakota State University, 2016)Genome-wide association study of heat stress tolerance in rapeseed/canola was conducted in greenhouse, growth chamber, and in the field. A total of 37,539 SNP markers were used in this study. In the greenhouse and growth ... -
Genome-wide Scan for Loci Affecting Iron Deficieny Chlorosis in Soybean.
(North Dakota State University, 2010)Iron deficiency results in iron deficiency chlorosis (IDC) in soybean grown in the north central regions of the United States. Soybean plants display a variety of symptoms, ranging from slight yellowing of the leaves to ... -
The Genomic Alteration Landscape of Pancreatic Duct Adenocarcinoma
(North Dakota State University, 2022)By 2030, PDAC is projected to be the second leading cause of cancer-related death in the US. PDAC is a multifactorial disease driven by genomic alterations. Understanding this alteration landscape will both refine the ... -
Genomic Analysis of Domestication-Related Traits and Stem Rust Resistance in Tetraploid Wheat
(North Dakota State University, 2017)Modern durum and common wheat cultivars were developed from ancient wheat ancestors by natural and artificial selection of agronomic and domestication traits, which ultimatey decreased their genetic diversity and made them ... -
Genomic Analysis of Septoria nodorum Blotch Susceptibility Genes Snn1 and Snn2 in Wheat
(North Dakota State University, 2019)Septoria nodorum blotch is a disease of wheat caused by the necrotrophic fungus Parastagonospora nodorum. In the wheat-P. nodorum pathosystem, recognition of pathogen-produced necrotrophic effectors (NEs) by dominant host ... -
Genomic Analysis of Tan Spot and Stagonospora Nodorum Blotch Resistance in Wheat
