Factors influencing storage quality of hazelnut varieties

Creator:: Ebrahem, Kais Shaheb
Abstract:: This thesis research is a series of five studies dealing with various aspects of hazelnut quality: 1. Identification of kernel mold and its incidence among hazelnut varieties. 2. Seasonal development and composition of kernels. 3. Hazelnut oil composition (fatty acids and tocopherols) of seventeen varieties. 4. Hazelnut oil composition compared...

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...

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...

A microscopic and phenological study of pollen development and bloom in selected cultivars of hazelnut (Corylus avellana)

Creator:: Tiyayon, Chantalak
Abstract:: Pollen development is an important process in male flower development, the timing of which may be correlated with time of pollen shed in hazelnut (Corylus avellana L.). Early to very late blooming cultivars were identified and the relationship of microsporogenesis and microgametogenesis, and time of pollen shed were studied in...

Husbandry stress of Zebrafish, Danio rerio

Creator:: Ramsay, Jennifer Mara
Abstract:: Zebrafish, Danio rerio, are widely used as vertebrate research organisms yet little is know about their responses to husbandry stressors. This dissertation examined the whole-body cortisol responses of zebrafish to husbandry stress. Additionally, the effects of stress on the susceptibility to mycobacteriosis and microsporidiosis (Pseudoloma neurophilia) were determined including effects...

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...

Breeding and genetics of lilacs and hardy hibiscus

Creator:: Lattier, Jason D.
Abstract:: Lilacs are a group of ornamental trees and shrubs in the Oleaceae family consisting of 22 to 30 species. There are six series within genus Syringa: Pubescentes, Villosae, Ligustrae, Ligustrina, Pinnatifoliae, and Syringa. Fertility and cross-compatibility among cultivars, species, and series have yet to be formally investigated. Over three years,...

Breeding qualitative and quantitative traits for potatoes in the Columbia Basin

Creator:: Graebner, Ryan C.
Abstract:: The cultivated potato (Solanum tuberosum L.) is one of the world’s most important staple crops, ranked fourth after maize, rice, and wheat. While the potato’s success is due largely to its high yield, it also benefits from its broad global acceptance, and its ability to be used by the consumer...

Phylogenetic Estimation and Ancestral State Reconstruction of Rubus (Rosaceae) using Target Capture Sequencing

Creator:: Carter, Katherine A.
Abstract:: Hybridization, polyploidy, and apomixis have made phylogenetic estimation in Rubus challenging. I used target capture to sequence approximately 1000 low copy nuclear loci and the chloroplast genome for 94 accessions representing the genus Rubus and distributed worldwide. Species phylogenies were estimated using two coalescent based methods, ASTRAL-II and SVDQuartets, and...
