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 ...
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 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 ...
Total Yellow Pigment Content and Oxidative Stress Level during Kernel Development
(North Dakota State University, 2013)
The focus of this research was to determine the effects of cultivar and environment on levels of total yellow pigment content and oxidative stress during grain development and in semolina and pasta. Lipoxygenase activity ...
Delayed Harvest Affects Quality of Durum Wheat
(North Dakota State University, 2017)
Harvest can be delayed for many reasons. This research was conducted to determine the effect of delayed harvest on grain and semolina quality of durum wheat (Triticum turgidum L. ssp. durum [Desf.] Husn.). Twelve durum ...
Analysis and Identification of QTL for Resistance to Sclerotinia Sclerotiorum in Pea (Pisum sativum L.)
(North Dakota State University, 2018)
White mold caused by Sclerotinia sclerotiorumi s one of the most devastating diseases infecting field pea (Pisum sativum L.) which causes severe yield loss worldwide. Population 17 (Lifter/ PI240515), and Population 19 ...
Unraveling the Genetics of Seed Dormancy in Barley Using Genome-Wide Association and Biparental Mapping
(North Dakota State University, 2013)
Seed dormancy is the delay or inability of viable seeds to germinate under favorable conditions. The differential expression of dormancy levels in barley (Hordeum vulgare L.) seeds impacts malt quality. While dormant ...
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 ...
Molecular Mapping of Fusarium Head Blight Resistance in Two Adapted Spring Wheat Cultivars
(North Dakota State University, 2015)
Releasing bread wheat (Triticum aestivum) cultivars with resistance to Fusarium head blight (FHB) disease can be endangered by narrowing the variation in genetic sources. However, resistance to FHB rely on five different ...
