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 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 ... -
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 ... -
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 ... -
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 Molecular Markers Linked to X-Disease Resistance in Chokecherry
(North Dakota State University, 2012)X-disease, caused by phytoplasmas, is one of the destructive diseases in stone fruit trees, causing yield loss and poor fruit quality. So far no effective methods are available to control X-disease. X-disease resistance ... -
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 ... -
Impact of Planting Date, Cultivar, Phosphorus, Potassium, and Fungicide Seed Treatments on Winter Wheat Survival and Yield
(North Dakota State University, 2014)Field experiments and greenhouse studies were conducted to evaluate the effects of phosphorus (P), potassium (K), and fungicides on winter survival, and yield of winter-wheat in North Dakota. The study was conducted as a ... -
Improving Efficacy of Metribuzin and Rimsulfuron in Potato Production
(North Dakota State University, 2016)Rimsulfuron and metribuzin are postemergence herbicides used to control broadleaf weeds in potato and are applied with adjuvants to improve efficacy. Postemergence weed control often coincides with fungicide treatments. ... -
Inheritance of Partial Resistance to White Mold in Field Pea (Pisum sativum L.)
(North Dakota State University, 2012)Sclerotinia sclerotiorum causes white mold and severe yield losses of pea. 484 accessions from the Pisum core collection were screened for resistance using a mini-agar plug technique. 49, 41, and 13 accessions were identified ... -
Integrated Pest Management of Canada Thistle (Cirsium Arvense L.)
(North Dakota State University, 2012)Canada thistle is a clone forming perennial weed that spreads aggressively and is difficult to control. One approach to managing invasive weeds is integrating numerous tactics instead of relying on a single tactic. Therefore, ... -
