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’ ... -
Rotating Cross-Arm and Winter Row Covers for Floricane Blackberry (Rubus Subgenus Rubus Watson) Production in North Dakota
(North Dakota State University, 2016)Blackberry (Rubus subgenus Rubus Watson) production has potential to expand into North Dakota, but this will only occur with the evaluation of new cultivars and overwintering protection methods. Ten cultivars under four ... -
Symmetric Protoplast Fusion in Interserial Syringa (Oleaceae) Hybridization
(North Dakota State University, 2016)Few other woody plants embody the preeminence of temperate woody plants in garden cultivation like the lilacs. In spite of their relationship, the trees lack the diversity of cultivated floral forms observed within the ... -
Selection of Hard Red Winter Wheat Lines with Diverse Resistance to Leaf Spot Diseases
(North Dakota State University, 2016)Tan spot and Septoria nodorum blotch cause serious yield losses in winter wheat in North Dakota as the majority of commercially grown cultivars are susceptible. This study aimed to identify lines with improved resistance ... -
Variation in Core and Accessory Parts of Genome of Escherichia Coli Isolated from Soil from Riparian Areas in New York State
(North Dakota State University, 2016)Escherichia coli is commensal bacteria and is a symbiont of the digestive system of vertebrates. Due to frequent deposition of E. coli into extrahost habitats (soil, water), approximately half of its population exists as ... -
Susceptible Crop Response to Soil Residues and Foliar Exposure of Dicamba
(North Dakota State University, 2016)Dry bean, soybean, sugarbeet, and sunflower were tested for tolerance to dicamba residue in soil. Visible injury was seen on dry bean and soybean depending on location, but yield differences were not present. Increasing ... -
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 ... -
Validation of Molecular Markers Associated with Grain Cadmium in Durum Wheat (Triticum turgidum L. var. durum Desf.)
(North Dakota State University, 2016)Durum wheat is capable of accumulating cadmium, a toxic heavy metal, in the grain at levels that have been deemed unsafe. Previous studies have identified genetic variation in durum wheat that can be exploited to create ... -
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. ... -
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, ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
