Biochemical And Morphological Analyses Of The Hordeum Jubatum-Brachyantherum-Caespitosum Hybrid Complex, Gareth Roz Babbel
Theses and Dissertations
Hordeum jubatum L., Hordeum brachyantherum nevski, and Hordeum jubatum var. caespitosum (Scribn.) Hitchc. Plants from sites in Utah and Idaho were grown and examined in order to determine whether or not hybridization with subsequent introgression occurs among the species and if so whether there is a difference in the relative amount of gene flow between the parent species H. jubatum and H. brachyantherum in different environments. Hybridizations and morphological analyses were made using standard procedures. Biochemical analyses were made by comparing paper chromatograms of leaf extracts of plant specimens. The results indicate that in Utah populations sampled, hybridization with subsequent …
