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 ...
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 ...
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’ ...
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 ...
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 ...
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 ...
Phytoremediation of Soils Contaminated by Oil and Gas Drilling and Production Operations Using Grass Species
(North Dakota State University, 2014)
Soil contaminated by crude oil or drill cuttings poses a threat to ecosystem. The objective of this study was to test tolerance levels of grass species to drill cuttings and crude oil in seed germination and at the 5-leaf ...
Integrated Pest Management of Canada Thistle (Cirsium Arvense L.)
(North Dakota State University, 2012)
Canada thistle is a clone forming perennial weed that spreads aggressively and is difficult to control. One approach to managing invasive weeds is integrating numerous tactics instead of relying on a single tactic. Therefore, ...
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 ...
Inheritance of Partial Resistance to White Mold in Field Pea (Pisum sativum L.)
(North Dakota State University, 2012)
Sclerotinia sclerotiorum causes white mold and severe yield losses of pea. 484 accessions from the Pisum core collection were screened for resistance using a mini-agar plug technique. 49, 41, and 13 accessions were identified ...
