Genomic Analysis of Domestication-Related Traits and Stem Rust Resistance in Tetraploid Wheat
(North Dakota State University, 2017)
Modern durum and common wheat cultivars were developed from ancient wheat ancestors by natural and artificial selection of agronomic and domestication traits, which ultimatey decreased their genetic diversity and made them ...
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 ...
Identification and Validation of a New Source of Low Grain Cadmium Accumulation in Durum Wheat (Triticum Turgidum L. Subsp. Durum (Defs.))
(North Dakota State University, 2017)
Cadmium (Cd) is a toxic heavy metal with no known biological function. The maximum level of Cd concentration allowed in the international market for wheat grain is 0.2 mg kg-1. Higher Cd levels in durum wheat (Triticum ...
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 ...
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 ...
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 ...
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 ...
Productivity and Sustainability of Intercropping Systems in the Northern Great Plains
(North Dakota State University, 2017)
The sustainability and productivity of cropping systems in the northern Great Plains is at risk because food, feed, and energy are produced mainly in very short crop rotations or monocultures. High input agriculture and ...
