Genetic Dissection and Molecular Approaches of Root Morphology of Canola
(North Dakota State University, 2014)
The inheritance of root vigor and days to flowering were studied in the F2 populations derived from winter- and spring-type crosses and their reciprocal crosses. Root vigor was found to be controlled by three genes whereas, ...
Screening for Forage Sorghum Genotypes with Chilling Tolerance
(North Dakota State University, 2019)
Forage sorghum (FS) [Sorghum bicolor (L.) Moench] is a warm-season biomass crop with the potential to become a bioenergy feedstock. The objective of this study was to screen potential FS genotypes for increased chilling ...
Development and Evaluation of a Greenhouse Testing Procedure for Cold-Hardiness in Hard Red Winter Wheat
(North Dakota State University, 2015)
Experiments were conducted to develop a greenhouse test for comparing the cold tolerance of winter wheat genotypes. Winter-survival is a complex trait and in field trials it has low heritability, consequently, selection ...
Evaluation of Hard Red and White Spring Wheat Genotypes for Tolerance to Pre-Harvest Sprouting
(North Dakota State University, 2012)
Each genotype was exposed to controlled PHS conditions for evaluation of susceptibility or tolerance to sprouting, falling number, kernel color, test weight, and yield. The 24 genotypes were grown in replicated trials at ...
Plant-Parasitic Nematodes in Field Pea and Potato and their Effect on Plant Growth and Yield
(North Dakota State University, 2018)
In this study, surveys were conducted in pea and potato fields in North Dakota and Central Minnesota to investigate the incidence and abundance of plant-parasitic nematodes in these fields. Moreover, the effect of the pin ...
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 ...
