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 ... -
Early-Season Weed Control in Direct-Seeded Onion (Allium Cepa L.)
(North Dakota State University, 2012)Onion is a poor competitor with early-season broadleaf weeds. In addition, there are no current herbicide labels that allow POST application prior to the onion two-leaf stage in ND and PRE herbicide options provide ... -
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 ... -
Environmental Influence on Cold-Climate Grapevine (Vitis Spp.) Fall Acclimation Response and Fruit Ripening
(North Dakota State University, 2016)Two experiments were conducted to determine differences in sensitivity to temperature among cold-climate grapevine genotypes in fall-acclimation response. One experiment utilized a growth chamber to compare grapevine ... -
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. ... -
Genetic and Physiological Relationships between Oat Grain Quality Components
(North Dakota State University, 2013)The use of oats for human consumption is increasing every day due to the health benefits of oat products. With the objective to study relationships among factors affecting oat grain quality, two Recombinant Inbred Lines ... -
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, ... -
Genetic Diversity and Genome-Wide Association Mapping of Agronomic, Disease Resistance, and Quality Traits in Barley Accessions from Ethiopia, Icarda, and the U.S.
(North Dakota State University, 2015)Plant breeding is a dynamic process that incorporates new germplasm to introduce genetic variation. Knowledge gained from genetic diversity studies and identification of potentially useful germplasm is critical for efficiently ... -
Genetic Investigation of Wild Oat with Acetyl-Coa Carboxylase Gene Sequence Variation
(North Dakota State University, 2013)Wild oat (Avena fatua) is a grass weed species that infests cropland. Common post-emergent herbicides for controlling wild oat are those that inhibit acetyl-CoA carboxylase (ACCase) and acetolactate synthase (ALS). Variation ... -
Genetics and Quantitative Trait Loci Mapping of Septoria Tritici Blotch Resistance, Agronomic, and Quality Traits in Wheat
