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 ... -
Association Mapping of Agronomic Traits of Dry Beans Using Breeding Populations
(North Dakota State University, 2014)Genome wide association mapping (GWAS) is an effective method to fine-map QTL because of its higher mapping resolution. In order to evaluate the possibility of using breeding populations for GWAS, analysis were conducted ... -
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 ... -
Dark, Hard and Vitreous (DHV) HRS Wheat Kernel Content Effect on Flour and Baking Quality
(North Dakota State University, 2014)Kernel vitreousness is an important grading characteristics of Hard Red Spring (HRS) wheat in the U.S., as subclasses vary in the dark, hard and vitreous kernel (DHV) content. This research investigated different subclasses ... -
Quinclorac and Aminocyclopyrachlor Movement in Sandy Soils of the Sheyenne National Grassland, and Control of Yellow Toadflax with Aminocyclopyrachlor
(North Dakota State University, 2014)Quinclorac and aminocyclopyrachlor leaching potential was evaluated in replicated field conditions in soil from five ecological sites of the Sheyenne National Grassland (SNG). Herbicide concentration was estimated using ... -
Droplet Size Effect on Herbicide Used in Cereals to Control Dicotyledonous Weeds
(North Dakota State University, 2014)Experiments were conducted to evaluate the effect of droplet size on the efficacy of translocated and non-translocated herbicides. Translocated and non-translocated herbicides provided similar control when comparing droplet ... -
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 ... -
Raised Beds, Tile Drainage, and Nitrogen Fertilizer Management on Corn Yield in Eastern North Dakota
(North Dakota State University, 2014)Surface drainage, tillage, and different nitrogen fertilizer rates and management practices can influence corn (Zea mays L.) grain yield. The objective of this research was to evaluate the effect of subsurface drainage, ... -
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 ... -
Genetic Dissection and Molecular Approaches of Root Morphology of Canola
(North Dakota State University, 2014)The inheritance of root vigor and days to flowering were studied in the F2 populations derived from winter- and spring-type crosses and their reciprocal crosses. Root vigor was found to be controlled by three genes whereas, ... -
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 ... -
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 ... -
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. ... -
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 ... -
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 ... -
The Acquisition of Useful Disease Resistance Genes for Hard Red Winter Wheat Improvement
(North Dakota State University, 2015)This study was part of a larger pre-breeding effort to develop new parental materials carrying useful genes for disease resistance and adaptation. Firstly, marker-assisted backcrosses were employed to transfer and pyramid ... -
Development and Evaluation of a Greenhouse Testing Procedure for Cold-Hardiness in Hard Red Winter Wheat
(North Dakota State University, 2015)Experiments were conducted to develop a greenhouse test for comparing the cold tolerance of winter wheat genotypes. Winter-survival is a complex trait and in field trials it has low heritability, consequently, selection ... -
