  • Developmental mutants of Phaseolus vulgaris L.

    Creator:
    Shii, Chou Tou
    Abstract:
    Hybrids with abnormal development were obtained when particular genotypes of Phaseolus vulgaris L. were crossed. The phenotypic aberrations of the F₁s included retarded growth, chlorosis of the trifoliate leaves and the formation of adventitious roots on the hypocotyls. The expression of the abnormalities was dependent on the temperature. At high...

  • Inducing and Evaluating Phenotypic and Cytometric Variation in Landscape Plants : Observations from Acer, Ornithogalum, and Penstemon

    Creator:
    Lattier, Kim Shearer
    Abstract:
    Hereditary variation is a vital component in the development of new and improved cultivars of landscape plants. Sources of hereditary variation include naturally occurring variation, recombination due to controlled crosses, artificial mutagenesis, and genetic modification via biotechnology. Here I explore all methods with the exception of genetic modification via biotechnology....

  • Isozyme banding patterns and embryo development in interspecific crosses of Phaseolus

    Creator:
    Guo, Mei
    Abstract:
    Interspecific hybridization between Phaseolus vulgaris and P. coccineus results in the formation of either mature F₁ seeds or abnormal embryos, depending on the direction of the cross. However, normal as well as abnormal embryos occur in the reciprocal F₂ populations. The exact cause of abnormal embryo development is unknown. To...

  • RFLP analyses of interspecific hybrids of Phaseolus

    Creator:
    Kuo, Mei
    Abstract:
    Gene transfer via interspecific hybridization within Phaseolus has been limited by abnormal hybrid development and the rapid loss of hybridity in subsequent generations. The most advanced embryo development occurs in P. vulgaris x P. coccineus where mature seeds form. However, the reciprocal cross still results in abnormal embryos unable to...
