Adaptation of Quality Protein Maize (Zea Mays L.) to Northern U.S. Corn Belt
(North Dakota State University, 2015)There is a need to increase the value of crops and develop the next generation of healthier products. Quality protein maize (Zea mays L.) is an option but has never been adapted to short – season environments. Quality ... -
Advanced Cropping Systems for Oil and Biomass Feedstock Production in the Northern Great Plains
(North Dakota State University, 2015)Video summarizing a Ph.D. dissertation for a non-specialist audience. -
Agronomic Practices that Impact Grain Quality Factors of Durum Wheat (Triticum Turgidum L. Var. Durum Desf.)
(North Dakota State University, 2016)Durum wheat is a type of wheat primarily used for pasta production. North Dakota is the leading producer of durum wheat in the US with average yields of 2700 kg ha-1. Durum wheat price discounts are common and occur due ... -
Agronomic Studies of Forage Brassicas as Full-Season and Cover Crops for Grazing in North Dakota
(North Dakota State University, 2017)Annual forages represent a good feed resource to extend the grazing season into fall and winter, providing a good quality forage for the livestock, allowing more efficient use of rangeland, and at the same time improving ... -
Association Mapping and Genetic Diversity Studies of Agronomic and Quality Traits in Durum Wheat [Triticum turgidum L. var. durum (Desf.)]
(North Dakota State University, 2017)Genetic diversity studies in breeding programs are important to identify parental lines for hybridization and introgression of desirable alleles into elite germplasm. The genetic diversity analysis of 283 North Dakota ... -
Characterization and Manipulation of the Wheat B Genome
(North Dakota State University, 2017)Common wheat originated from interspecific hybridization of three diploid ancestors followed by spontaneous chromosome doubling. Aegilops speltoides (genome SS) has been controversially considered a possible candidate for ... -
Characterization of Common Wheat Translocations Carrying Leaf Rust Resistance Genes from Alien Species
(North Dakota State University, 2016)Leaf rust caused by Puccinia triticina Erikss may inflict significant yield losses in wheat; however, can be controlled by breeding for increased host resistance. In earlier studies, effective, resistance has been transferred ... -
Cloning and Characterization of Meiotic Genes Rec8 and Cdc5 and Subcellular Analysis of Kinetochore Orientation in Wheat
(North Dakota State University, 2013)Meiosis is a specialized cell division that halves chromosomes and generates haploid gametes in eukaryotes. It is a dynamic cellular process governed by a complex genetic network. Two key players of this network, Rec8 and ... -
Cloning and Characterization of the Iron-Regulated Transporter (IRT) Genes and Their Transcription Factors in Populus
(North Dakota State University, 2015)Iron deficiency causes chlorosis in many plant species, resulting in yield loss and poor quality. Many tree species including poplar are susceptible to iron deficiency. Trees suffering from iron deficiency often show ... -
Determining Optimum Seeding Rates for Diverse Hard Red Spring Wheat (Triticum Aestivum L.) Cultivars
(North Dakota State University, 2016)Seeding rate for maximum grain yield can differ for diverse hard red spring wheat (HRSW) (Triticum aestivum L.) cultivars and can be derived from a seeding rate response curve. Six groups of HRSW cultivars with combinations ... -
Developing a DNA Fingerprint for Midwest Six-rowed Malting Barley
(North Dakota State University, 2012)The requirements for brewing beer from barley (Hordeum vulgare L.) malt are specific and unique for each brewer. Anheuser-Busch InBev and Miller Coors Brewing Company (MillerCoors) are two major brewers in the United States ... -
Development and Characterization of Wheat Germplasm for Resistance to Stem Rust UG99 in Wheat
(North Dakota State University, 2013)World wheat production is currently threated by stem rust (caused by Puccinia graminis f. sp. tritici) Ug99 race (TTKSK). The ongoing global effort to combat Ug99 is focusing on the identification and deployment of ... -
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 ... -
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 ... -
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 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 ... -
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 ... -
