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 ... -
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 ... -
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 ... -
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, ... -
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 ... -
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, ... -
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 ... -
Association Mapping of Agronomic Traits of Dry Beans Using Breeding Populations
