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 ... -
Aminocyclopyrachlor Efficacy on Native Forbs, and Soil Seedbank Change 15 Years Following Release of Leafy Spurge (Euphorbia esula L.) Biological Control Agents
(North Dakota State University, 2016)Native prairie response to aminocyclopyrachlor (AMCP) was evaluated in the Northern Great Plains. AMCP altered plant communities and reduced foliar cover of introduced, high seral, and low seral forb species. After treatment, ... -
Aminocyclopyrachlor: Weed Control, Soil Dissipation, and Efficacy to Seedling Grasses
(North Dakota State University, 2012)Aminocyclopyrachlor was developed for invasive weed control in non-cropland. Weed control, soil dissipation, and seedling grass tolerance with aminocyclopyrachlor were evaluated in field and greenhouse trials. Weed control ... -
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 ... -
Characterization of Selected Winter Hardiness Traits in Pea (Pisum Sativum L.)
(North Dakota State University, 2013)Pea (Pisum sativum L.) is an important crop from an agronomic and nutritional standpoint. Winter pea has further agronomic benefits for producers; however, sufficient winter hardiness to survive harsh North Dakota conditions ... -
Cover Crops Impact on Energy and Forage Crops Productivity in North Dakota
(North Dakota State University, 2013)Forage crops have gained interest as potential source of lignocellulosic feedstock to produce ethanol. More focus is needed on developing cropping systems to improve productivity. This study was conducted to identify the ... -
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 ... -
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 ... -
Differential Response to Foliar Pathogens in Wheat as a Consequence of Cytoplasmic Substitution
(North Dakota State University, 2013)Wheat alloplasmic lines are plants where the cytoplasmic genome of one wheat species was substituted by those of a wild relative, while maintaining the original nucleus. Our project studied differential responses of various ... -
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 ... -
Effects of Competitive and Allelopathic Interactions on Field Pea and Soybean under Organic Management
(North Dakota State University, 2013)Experiments were conducted during 2011 and 2012 at Dickinson Research Extension Center (DREC), ND and at Carrington Research Extension Center (CREC) to understand the effects of competitive and allelopathic interactions ... -
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 ... -
Enhancing Protein Concentration in Hard Red Spring Wheat with Nitrogen Management Based on Plant Predictors
(North Dakota State University, 2013)In recent years (2009-2011) many producers have had issues meeting the market requirements of 140 g kg-1 of protein concentration in hard red spring wheat (HRSW) (Triticum aestivum L. emend. Thell) especially with newer ... -
Evaluation of a Systematic, Multichemical Program Approach for Wheat Pest Management and Evaluation of a New Fungicde for Tan Spot in Spring Wheat (Triticum Aestivum. L.)
(North Dakota State University, 2013)Experiments were conducted to evaluate Proceed Plus (prothioconazole & tebuconazole & metalaxyl & clothianidin), bixafen, Prosaro (prothioconazole & tebuconazole), Baythroid XL (beta-cyfluthrin), with ‘Glenn’ and ‘Oklee’ ... -
Evaluation of Hard Red and White Spring Wheat Genotypes for Tolerance to Pre-Harvest Sprouting
(North Dakota State University, 2012)Each genotype was exposed to controlled PHS conditions for evaluation of susceptibility or tolerance to sprouting, falling number, kernel color, test weight, and yield. The 24 genotypes were grown in replicated trials at ... -
Factors Impacting Corn Establishment and the Role of Uniform Stand Establishment on Yield
(North Dakota State University, 2016)Information from actual farm fields can help corn producers understand the value and importance of establishing uniform plant emergence and within row plant spacing. Thirty-eight fields planted with corn (Zea mays L.) by ... -
Frontenac' Response to Leaf Removal and Training Systems and a Microvinification and Deacidification Bioassay of Interspecific Hybrids (Vitis SPP.)
(North Dakota State University, 2016)Vineyard production and acid reduction microvinification experiments were conducted on interspecific hybrid grape cultivars in North Dakota. Training system and leaf removal effects on yield and quality for ‘Frontenac’ ... -
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. ... -
