Pathogenic Variation, Host Specialization and Aggressiveness in Helminthosporium Sativum
(North Dakota State University, 1984)
Common root rot, caused by Cochliobolus sativus, is an important disease of spring wheat and barley in the northern Great Plains. While the disease has been widely studied, extensive systematic investigation of pathological ...
Characterizing Pyrenophora Teres F. Maculata in the Northern United States and Impact of Spot Form Net Blotch on Yield of Barley
(North Dakota State University, 2015)
Pyrenophora teres f. maculata causes spot form net blotch (SFNB) on barley and was recently documented in North Dakota. The impact of SFNB on barley, the genetic diversity of the pathogen, and virulence structure are unknown ...
Genetic and Molecular Characterization of Host Resistance and Susceptibility to Pyrenophora Teres F. Teres in Hordeum vulgare
(North Dakota State University, 2016)
Pyrenophora teres f. teres, a necrotrophic fungal pathogen and causal agent of net form net blotch (NFNB), is an economically important pathogen of barley (Hordeum vulgare) and has potential to cause significant yield ...
Genetic Structure of Leptosphaeria Maculans Populations in North Dakota and Identification of Genes Associated with Resistance to L. Maculans in Brassica Juncea
(North Dakota State University, 2013)
Blackleg, caused by Leptosphaeria maculans is one of the most devastating diseases of canola (Brassica napus) in North Dakota. A study was conducted to characterize prevalence of pathogenicity groups (PG), identify population ...
Inoculation Techniques, Development of Brassica Napus Breeding Lines and Identification of Markers Associated with Resistance to Sclerotinia Sclerotiorum (Lib.) De Bary
(North Dakota State University, 2012)
Sclerotinia stem rot caused by Sclerotinia sclerotiorum (Lib.) de Bary is an economic disease affecting canola (Brassica napus L). Since expression of sclerotinia stem rot symptoms shows much variability and the trait is ...
Characterization of Pea Seed-Borne Mosaic Virus, Efficacy of Foliar Applications for Common Bacterial Blight Management in Dry Beans and Impact of Common Bacterial Blight on Prostrate and Upright Beans
(North Dakota State University, 2018)
PSbMV in field pea has resulted in substantial yield and seed quality losses world-wide and has recently been reported in North Dakota. Traditional management of this virus includes preventative measures such as removal ...
Histology of Spot Blotch Infection in Barley, QTL Mapping of Resistance to Fusarium Head Blight, and Characterization of Root Rot Diseases in Wheat
(North Dakota State University, 2017)
Three independent studies were conducted for spot blotch (Bipolaris sorokiniana), Fusarium head blight (FHB) (Fusarium graminearum), and root rot diseases (Fusarium species and B. sorokiniana). Histopathology of compatible ...
Towards Identifying the Physical and Molecular Components Involved in Resistance to Leaf Rust Pathogen Puccinia Triticina in Wheat and Barley
(North Dakota State University, 2016)
Genetic resistance is the preferred method to reduce yield losses caused by many diseases including wheat leaf rust. However, in many cases host resistance seems to be short-lived. For decades, scientists have tried and ...
Comparative Population Genetics of Fusarium Graminearum and Novel Sources of Resistance to Fusarium Head Blight in Spring Wheat
(North Dakota State University, 2013)
Fusarium graminearum is the major causal agent of Fusarium head blight (FHB) in cereal crops. The fungus produces several types of trichothecenes [Deoxynivalenol (DON) and its acetylated derivatives, 3-acetyldeoxynivalenol ...
Biology and Development of Two Wilt Fungi of Potato: Verticilliam Dahliae and Colletotrichum Coccodes
(North Dakota State University, 2012)
The demand for high quality tubers for the frozen processing industry has exerted increased pressure on producers to control diseases that can compromise tuber quality, including, C. coccodes and V. dahliae. Infection of ...
