Genetic Characterization of Dormancy in Durum Wheat
(North Dakota State University, 2012)Two populations derived by crossing LDN x LDN Dic-3A (Population I) and LDN x LDN Dic-3B (Population II) were genetically characterized for the seed dormancy present on chromosome 3A and 3B of durum wheat. The genes for ... -
Genetic Dissection and Improvement of Fusarium Head Blight Resistance in Durum Wheat
(North Dakota State University, 2022)Fusarium Head Blight (FHB) is a destructive and complex fungal disease in wheat. Durum wheat, an economically important crop for pasta production, is under the severe impact of FHB. While numerous favorable QTL/genes have ... -
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 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 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 Drought Tolerance in Hard Red Spring Wheat in the Northern United States of America
(North Dakota State University, 2017)Drought affects about 50% of wheat (Triticum aestivum L.) globally and is a major threat for sustainable wheat production. This dissertation discusses three studies carried out to dissect drought tolerance in hard red ... -
Genetics of End-Use Quality Characteristics in Spring Wheat (Triticum Aestivum L.)
(North Dakota State University, 2017)Wheat (Triticum aestivum L.) is one of the most important crops consumed by humans around the world. Improving the end-use quality traits is one of the major objectives in wheat breeding programs. However, little is known ... -
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 Mapping and Genomic Prediction for Resistance to Sclerotinia Stem Rot in Rapeseed/Canola (Brassica napus L.) Germplasm Collections
(North Dakota State University, 2021)Sclerotinia stem rot (SSR), caused by Sclerotinia sclerotiorum, is a devastating disease of rapeseed/canola that causes significant seed yield loss, reduced oil content, and quality. Lack of complete immune genotypes and ... -
