Genetic resistance to white mold (Sclerotinia sclerotiorum (Lib.) De Bary) in scarlet runner beans (Phaseolus coccineus L.)

Creator:: Gilmore, Barbara S.
Abstract:: White mold, caused by Sclerotinia sclerotiorum (Lib.) De Bary, is a destructive yield-limiting disease of common bean (Phaseolus vulgaris L.). Genetic resistance to this pathogen is limited in common bean. Identification of high levels of partial physiological resistance in a genetically cross compatible species, Phaseolus coccineus, is advisable. The objectives...

Evaluation of genetic diversity in wild populations of black raspberry (Rubus occidentalis L.)

Creator:: Dossett, Michael
Abstract:: In recent years, there has been renewed interest in black raspberry (Rubus occidentalis L.) breeding. This has been spurred, in part, by an increase in black raspberry consumption due to studies that have shown them to be particularly high in anthocyanin content indicating high levels of antioxidants. Present cultivars are...

Localization and genetic mapping of some factors influencing rachis brittleness and free-threshing habit in wheat

Creator:: Nalam, Vamsi J.
Abstract:: Domesticated forms of wheat exhibit traits that have increased their adaptation to cultivation by humans. Some of the most critical adaptive differences involve changes to morphological features that make the crop easier to harvest like ear rachis stiffness (brittle to non-brittle rachis) and the ease with which the seed is...

Genetic mapping of Cuphea lanceolata : molecular-marker linkage to quantitative-trait loci affecting seed capric acid, seed oil, and embryo development

Creator:: Webb, David M. (David Morton), 1954-
Abstract:: Cuphea is an herbaceous genus having species whose seed storage lipids are predominantly medium-chain triglycerides (MCTs). Cuphea lanceolate Ait, and Cuphea viscosissima Jacq. are central to the breeding of Cuphea as a new commercial source of MCTs. The objectives of this thesis were to develop a reliable method to extract...

Single nucleotide polymorphism diversity in domesticated and wild sunflowers

Creator:: Freeman, Carrie
Abstract:: Single nucleotide polymorphisms (SNPs) are the most common DNA polymorphisms in plant and animal genomes. SNPs were identified in the allele sequences of up to 12 sunflower (Helianthus annuus L.) genotypes for a genome-wide sample of 81 loci originally mapped using restriction fragment length polymorphism (RFLP) markers. The RFLP loci...

Investigation of hop downy mildew through association mapping and observations of the oospore

Creator:: Parker, Thomas B.
Abstract:: Hop downy mildew is a devastating disease affecting hop requiring expensive fungicide applications throughout the growing season. Plant resistance is highly desirable and theorized as being decidedly quantitative with dominance and epistasis involved in resistance. An association mapping approach using a mixed-model was used to identify AFLP markers associated with...

Development and use of molecular tools in Fragaria

Creator:: Njuguna, Wambui
Abstract:: This dissertation describes the application and development of molecular tools that have great potential for use in studying variation in strawberry germplasm. The first study evaluated 91 microsatellite (simple sequence repeat, SSR) markers for transferability in 22 Fragaria species and their utility in fingerprinting octoploid strawberries. Out of the transferable...
