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 ... -
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 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 ... -
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 ... -
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, ... -
Juneberry (Amelanchier Alnifolia) Micropropagation and Cultivar Evaluation in North Dakota
(North Dakota State University, 2012)A growth chamber experiment was carried out for ten weeks to reduce post-rooting dormancy in juneberry micropropagation. An RCBD with a split plot arrangement and three replicates were used. Plantlets subjected to 750 mg/L ... -
Management Practices for Improved Winter Survival of Winter Wheat in North Dakota
(North Dakota State University, 2012)Hard red winter wheat (winter wheat, Triticum aestivum L.) production has been historically low in ND due to cold winter temperatures resulting in winter injury and stand loss. The objective of this research was to determine ... -
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 ... -
Micropropagation of the Relict Genus Cercidiphyllum (Cercidiphyllaceae)
(North Dakota State University, 2014)Focusing on various aspects of micropropagation with respect to well represented genotypes within Cercidiphyllum, this study is an attempt to broaden the experimental knowledge of the genus. The Tertiary relict Cercidiphyllum ... -
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 ... -
Nitrogen Uptake and Biomass and Ethanol Yield of Biomass Crops as Feedstock for Biofuel
(North Dakota State University, 2012)Nitrogen fertilizers are extensively used to enhance the growth of biomass crops. This study was conducted to determine the effect of N rates on the biomass yield and quality, and N uptake of several crops. The experiment ... -
Propagation of American Hophornbeam (Ostrya virginiana (Mill.) K. Koch.)
(North Dakota State University, 2014)American Hophornbeam (Ostrya virginiana (Mill.) K. Koch) is an underutilized ornamental landscape tree with limited species improvement partially as a result of a lack of a clonal propagation protocol and its slower growth ... -
