  • 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...

  • Rubus spp. seed germination and morphology

    Creator:
    Peacock, Derek N.
    Abstract:
    Rubus spp. seeds have a thick protective endocarp and testa (seedcoat) that can restrict germination even under favorable conditions. The effect of pregermination treatments were studied in Rubus chamaemorus L., R. eustephanos Focke ex Diels, R. idaeus 'Amber' L., R. leucodermis Douglas ex Torrey & A. Gray, R. multibracteatus A....

  • Disease resistance and spring phenological characteristics of Ribes L. germplasm

    Creator:
    Dalton, Daniel T.
    Abstract:
    North American cultivation of Ribes L. may expand as small fruit growers seek species to diversify horticultural crops. The Ribes industry was suppressed for decades out of fear that cultivated black currants and gooseberries would intensify the fungal disease white pine blister rust (WPBR) on five-needle pine (Pinus L. section...

  • Powdery mildew (Podosphaera macularis Braun & Takamatsu) resistance in wild hop genetic resources

    Creator:
    Smith, Jodi M.
    Abstract:
    Hop powdery mildew, caused by Podosphaera macularis Braun & Takamatsu (formerly Sphaerotheca macularis (Wallr. :Fr.) Lind, syn. S. humuli (DC.)Burrill) was not observed in Pacific Northwest hop yards until 1997, when it was discovered in Washington. Within one year, it had spread to Oregon and Idaho. This emerging disease caused...
