Creator:: Sathuvalli, Vidyasagar R.
Abstract:: European hazelnut, Corylus avellana L., is the only economically important nut crop in the family Betulaceae. One of the threats to the hazelnut industry in the Pacific Northwest is the fungal disease eastern filbert blight (EFB) caused by the pyrenomycete Anisogramma anomala. Host genetic resistance to EFB identified in the...

Creator:: Gürcan, Kahraman
Abstract:: New highly polymorphic simple sequence repeat (SSR) markers for European hazelnut (Corylus avellana L.). were developed from several sources. The markers were characterized, and segregation in a mapping population allowed to assign them to linkage groups. Their transferability across genera and species in the Betulaceae family was investigated. SSR markers...

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...

Creator:: Pino, María-Teresa
Abstract:: Solanum species differ in their degree of frost tolerance and cold acclimation capacity. Cultivated potato species of Solanum tuberosum L. are frost-sensitive, incapable of cold acclimation, and have a maximum freezing tolerance of –3°C. Solanum commersonii Dun is frost-tolerant and can survive to –5ºC pre-acclimation and –10ºC post-acclimation. Breeding attempts...

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,...

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...

Creator:: Li, Ning
Abstract:: Imaging spectra of plant tissues yield considerable potential and useful information for basic studies and agriculture practice. We constructed an imaging spectrophotometer with spectral range from 400 nm to 1100 nm, which was used to study various physiological events of plant germplasm: location of bundle sheath and mesophyll cells in...

Creator:: Kusolwa, Paul Mbogo
Abstract:: Interspecific hybridization was initiated between wild P. acutifolius accession G40199 and P. vulgaris to introgress resistance to Acanthoscelides obtectus (bean seed weevil). F1 interspecific hybrids were recovered by embryo rescue and maintained until flowering. Mostly sterile hybrids were backcrossed twice to common bean cultivar ICA Pijao to recover sufficient fertility...
