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 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 ... -
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 and Molecular Characterization of Pyrenphora teres f. teres
(North Dakota State University, 2019)Pyrenophora teres f. teres is the causal agent of net form net blotch of barley. P. teres f. teres is prevalent globally across all barley growing regions and globally is the most devastating foliar disease of barley. ... -
Genotype and Environmental Effects on Quality Traits of Durum Wheat Grown in North Dakota
(North Dakota State University, 2020)Variation in grain, semolina, dough strength, and pasta quality traits were evaluated using the effect of genotype and weather factors (air temperature, rainfall, and relative humidity). In addition, size exclusion high ... -
Genotype-by-Environment Interaction in Sunflowers for the Northern Plains
(North Dakota State University, 2018)Genotype by environment interaction (GxE) is the tendency of the phenotypic performance of two or more plant genotypes in one environment to not be predictive of their relative performance in another environment. To discover ... -
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 ... -
Glutograph 'E': A Simple Rheometer to Measure Quality of Cooked Pasta
(North Dakota State University, 2016)Glutograph ‘E’ was designed to determine the stretch and relaxation properties of wet gluten. Usage of this equipment to evaluate the cooked pasta texture has not been reported and thus is the goal of this research. ... -
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 ... -
H13 Efficacy as a Spring Cereal Crop Herbicide
(North Dakota State University, 2012)H13 is an experimental herbicide that has activity on both broadleaf and grass weeds. This project evaluated H13 efficacy as a spring cereal herbicide by determining H13 site of entry into plants, tolerance of hard red ... -
Hammer and Roller Milling of Yellow Split Pea
(North Dakota State University, 2019)Blending nutrient-rich pulses into cereal-based convenience foods could benefit consumers and the cereal and pulse industries but first requires appropriate milling of raw pulses, for which there is no standardized method. ... -
