  • Determining ploidy level and nuclear DNA content in Rubus by flow cytometry

    Creator:
    Meng, Rengong
    Abstract:
    Nuclear DNA flow cytometry was used to differentiate ploidy level and determine nuclear DNA content in Rubus. Nuclei suspensions were prepared from leaf discs of young leaves following published protocols with modifications that included: increasing the stain concentration, adding the stain after the RN ase treatment instead of adding it...

  • 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...

  • 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...

  • 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...

  • 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,...

  • Validation of Molecular Markers Associated with Perpetual Flowering (PF) and Soluble Solids Content (SSC) in Strawberry (Fragaria xananassa Duch. ex Rozier)

    Creator:
    Salinas, Natalia R.
    Abstract:
    Strawberry is economically the most important berry crop grown worldwide and breeders are continuously striving to develop improved cultivars. So far, marker assisted breeding (MAB) in strawberry has been limited to the private sector. However, loci controlling some traits of economic importance such as perpetual flowering (PF) and soluble solids...
