Genetic Studies of Winter Hardiness in Pisum sativum L.
(North Dakota State University, 2017)Pea (Pisum sativum L.) is valued for its high protein content and symbiotic nitrogen fixation. The use of pea as a green manure and cover crop in rotations has been increasing. Pea is grown as a winter crop but current ... -
Genetics and Quantitative Trait Loci Mapping of Septoria Tritici Blotch Resistance, Agronomic, and Quality Traits in Wheat
(North Dakota State University, 2013)Most breeding programs aim at developing superior germplasm and better cultivars that combine high yield, disease and pest resistance, and end-use quality to satisfy the requirements of the growers as well as industry. A ... -
Genetics of Wheat Domestication and Septoria Nodorum Blotch Susceptibility in Wheat
(North Dakota State University, 2019)T. aestivum ssp. spelta Iranian type has long been thought to potentially be the direct non-free threshing hexaploid progenitor. I evaluated a RIL population derived from a cross between CS and Iranian spelta accession ... -
Genome Mapping and Molecular Markers for Ascochyta Blight Resistance in Pea (Pisum Sativum L.)
(North Dakota State University, 2012)Ascochyta blight is the most common disease of economic importance in peas (Pisum sativum L.) in North Dakota. Selection based on molecular markers would greatly facilitate identification of resistant varieties. A mapping ... -
Genome Wide Association Study of Basic Fruit Chemistry in the Cold Climate Wine Grapes (Vitis spp.)
(North Dakota State University, 2022)To overcome some of these challenges posed by ND climate, the utilization of native wild Vitis-derived varieties is the best possible option available. Despite advantageous environmental tolerances of native wild Vitis ... -
Genome-wide Association Study and Genomic Prediction for Pod Shatter Resistance in Brassica napus L.
(North Dakota State University, 2022)The release of seeds from a mature dry pod is known as shattering. Pod shattering results in significant yield losses in rapeseed/canola. An experiment was conducted in five environments in 2020 and 2021 under the field ... -
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 ... -
Genotype-by-Environment Interaction in Sunflowers for the Northern Plains
(North Dakota State University, 2018)Genotype by environment interaction (GxE) is the tendency of the phenotypic performance of two or more plant genotypes in one environment to not be predictive of their relative performance in another environment. To discover ... -
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 ... -
Glutograph 'E': A Simple Rheometer to Measure Quality of Cooked Pasta
(North Dakota State University, 2016)Glutograph ‘E’ was designed to determine the stretch and relaxation properties of wet gluten. Usage of this equipment to evaluate the cooked pasta texture has not been reported and thus is the goal of this research. ... -
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 ... -
H13 Efficacy as a Spring Cereal Crop Herbicide
(North Dakota State University, 2012)H13 is an experimental herbicide that has activity on both broadleaf and grass weeds. This project evaluated H13 efficacy as a spring cereal herbicide by determining H13 site of entry into plants, tolerance of hard red ... -
Hardwood Floricane Blackberry Cuttings & Production of Primocane Blackberry in North Dakota
(North Dakota State University, 2016)Blackberry (Rubus L. subgenus Rubus, Watson) is not a commercially produced crop in North Dakota since the available floricane cultivars are not winter hardy. Two experiments were performed to evaluate alternative methods ... -
Herbicide Screening in Industrial Hemp (Cannabis sativa L.) Production
(North Dakota State University, 2021)Lack of labeled herbicides for industrial hemp (Cannabis sativa L.) production in the U.S. accentuates urgency to identify herbicides for weed control. Weed competition reduced seed yield by 25 to 32%. Pre- and post-emergence ... -
High tunnels extend the growing season in warm season crops tomato, cucumber and bell pepper
(North Dakota State University, 2020)High tunnels are used to modify the crop environment by trapping solar energy, providing protection from unfavorable weather events, and extending the growing season in temperate regions. This project assessed yield and ... -
Hop Establishment Impacted by Mulch Type and Nitrogen Source
(North Dakota State University, 2017)Agronomic research is lacking for hops (Humulus lupulus), especially in North Dakota (ND) and the northern Great Plains, where demand has risen. This research was done to evaluate factors influencing hops establishment in ... -
Horseweed (Erigeron canadensis) Control in No-Till Soybean Systems on a Coarse Textured Soil
(North Dakota State University, 2020)Horseweed (Erigeron canadensis) is a competitive winter or summer annual broadleaf weed. When uncontrolled, horseweed can reduce soybean (Glycine max) yields by 93%. Research was conducted to advance our knowledge on ... -
Identification of New Sources of Resistance to Anthracnose in Climbing Bean Germplasm from Guatemala
(North Dakota State University, 2017)Anthracnose, caused by Colletotrichum lindemuthianum (Sacc. and Magnus) Briosi and Cavara is a fungal disease that affects common bean worldwide. Seed yield loses sometimes reach 100% when the seed is infected and environmental ... -
