Gene Expression Associated with Wound and Native Periderm Maturation in Potato Tubers
(North Dakota State University, 2011)Potato (Solanum tuberosum L.) is the world's fourth largest food crop and large financial losses are incurred each year from wound and bruise related injuries. However, little is known about the coordinate induction of ... -
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 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 Dissection of Tan Spot Resistance in Wheat
(North Dakota State University, 2020)Tan spot, caused by the necrotrophic fungal pathogen Pyrenophora tritici-repentis (Ptr), is a major foliar disease in wheat. QTL mapping and meta-QTL analysis are effective methods to understand genetic basis of tan spot ... -
Genetic Diversity of the Guatemalan Climbing Bean Collections
(North Dakota State University, 2017)Since common bean is the most important legume crop for human consumption around the world, bean breeders are challenged to increase production of beans while facing new problems like climate change. Guatemalan climbing ... -
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 ... -
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 ...
