Development of Management Tools for Sunflower Downy Mildew (Plasmopara Halstedii) and Rust (Puccinia Helianthi)
(North Dakota State University, 2016)
Downy mildew (Plasmopara halstedii) and rust (Puccinia helianthi) are two economically important diseases of sunflower (Helianthus annuus) in North Dakota. Both diseases are capable of causing significant reductions in ...
Identification and Genomic Mapping of Resistance to Bacterial Leaf Streak in Wheat
(North Dakota State University, 2015)
Bacterial leaf streak (BLS) of wheat, caused by Xanthomonas translucens pv. undulosa, is an important disease of wheat worldwide. Use of resistant cultivars is the most preferred way of managing BLS. The objective of this ...
Genetic Mapping of Quantitative Trait Loci for Resistance to Wheat Tan Spot Using Two Bi-Parental Populations
(North Dakota State University, 2015)
Tan spot, caused by Pyrenophora tritici-repentis (Ptr), is an economically important disease on both common wheat (Triticum aestivum L.) and durum (T. turgidum L. ssp. durum). Genetics of resistance to tan spot is complicated ...
Identification and Characterization of Pythium Spp. on Glycine Max (Soybean) in North Dakota
(North Dakota State University, 2013)
The Oomycete Pythium comprises one of the most important groups of seedling pathogens affecting soybean, causing both pre- and post-emergence damping off. Numerous species of Pythium have been identified and found to be ...
Genetic Mapping of Resistance to Bacterial Leaf Streak in Triticale
(North Dakota State University, 2017)
Bacterial leaf streak (BLS), caused by Xanthomonas translucens pv. undulosa (Xtu), is an important disease of wheat worldwide. The best way to control this disease in the field is the use of resistant cultivars. Although ...
Rhizoctonia Solani Damping-Off of Sugarbeet: Effect of Plant Growth Stage on Disease Severity and Management Using Penthiopyrad
(North Dakota State University, 2015)
Rhizoctonia solani is the most damaging pathogen on sugarbeet (Beta vulgaris L.) in North Dakota and Minnesota. Research was conducted to evaluate penthiopyrad for controlling R. solani and determine when the plants are ...
Identification of Multiple Virulence Loci in Pyrenophora Teres F. Teres Associated with Net Form Net Blotch in Barley
(North Dakota State University, 2013)
The necrotrophic fungal pathogen Pyrenophora teres f. teres causes the foliar disease net form net blotch (NFNB) on barley (Hordeum vulgare). To investigate the genetics of virulence in the barley- P. teres f. teres ...
Assessing Cereal Aphid Diversity and Barley Yellow Dwarf Risk In Hard Red Spring Wheat and Durum
(North Dakota State University, 2018)
Barley yellow dwarf (BYD), caused by Barley yellow dwarf virus and Cereal yellow dwarf virus, and is a yield limiting disease of small grains. A research study was initiated in 2015 to identify the implications of BYD on ...
Identification of Quantitative Trait Loci (QTL) Associated with Resistance to Initial Infection of Fusarium Head Blight in Spring Wheat
(North Dakota State University, 2017)
Video summarizing a Ph.D. dissertation for a non-specialist audience.
A Novel Genetic Linkage Map of Chokecherry (Prunus Virginiana L.) and QTL Mapping for X-Disease (Candidatus Phytoplasma Pruni) Resistance
(North Dakota State University, 2016)
A novel chokecherry genetic linkage map was constructed using 565 molecular markers and a previously published mapping population (n=101). Chokecherry (Prunus virginiana L.) is a potential model for genetic research of ...
