Usefulness of Expired Proprietary (Ex-PVP) Maize (Zea Mays L.) Germplasm for U.S. Northern Breeding Programs
(North Dakota State University, 2014)
Maize (Zea mays L.) inbred lines and hybrids are protected by U.S. Patent and/or Plant Variety Protection Act (PVPA). Protection lasts 20 years and it affects breeding access in a highly confidential and competitive market. ...
Causes of Dull Brown Color in Durum and Traditional Semolina Pasta
(North Dakota State University, 2019)
Bleaching of durum wheat (Triticum turgidum L. ssp. durum [Desf.] Husn.) was evaluated by determining the effect of grain moisture content, temperature, and wet/dry cycles with bulk water and with high relative humidity ...
Optimal Seeding Rates for New Hard Red Spring Wheat Cultivars in Diverse Environments
(North Dakota State University, 2019)
Seeding rate in hard red spring wheat (HRSW) (Triticum aestivum L.) production impacts input cost and grain yield. Predicting the optimal seeding rate (OSR) for HRSW cultivars can aid growers and eliminate the need for ...
Allelic Relationship of A. strigosa Crown Rust Resistance Factors and their Relationship to Pc38 Suppression
(North Dakota State University, 2018)
An investigation of the suppression effect of Pc38 on Pc94 was conducted by developing F2 segregating populations from genotypes possessing Pc38 and Pc94, together with a population void of the Pc38. Segregating phenotypic ...
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 ...
Characterization of Surfactant Quality and Validation of Standard Water Conditioning Testing
(North Dakota State University, 2018)
Adjuvants are products added to pesticide applications to increase pest control. There are many different types of adjuvants designed to solve certain problems. Surfactants are a major class of agricultural adjuvant used ...
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 ...
Transfer of Fusarium Head Blight Resistance to Hard Red Winter Wheat
(North Dakota State University, 2019)
Fusarium head blight (FHB; caused by Fusarium graminearum Schwabe) is a serious disease of hard red winter wheat (HRWW) in North Dakota. Current varieties are lacking in resistance. Many resistance quantitative trait loci ...
