  • Breeding tomatoes for improved antioxidant activity

    Creator:
    Mes, Peter Jack, 1976-
    Abstract:
    Purple tomatoes (Lycopersicon esculemtum) were bred by incorporating genes that result in anthocyanin production in the skin of fruits. These genes originally came from related wild species as no naturally occurring genes encoding fruit anthocyanin expression are known within the cultivated species. By combining Aft or Abg with atv or...

  • Breeding tomato for increased fruit phenolics

    Creator:
    Boches, Peter S.
    Abstract:
    The purpose of this research was to develop tools and germplasm for the production of tomatoes (Solanum lycopersicum L.) with high fruit phenolics without the use of genetic engineering. A candidate gene analysis was undertaken to identify genes regulating anthocyanin biosynthesis in tomato fruit (Aft, Abg, atv, and Purple Smudge)....

  • Alternative greenhouse tomato production system

    Creator:
    Albahouh, Muhammed S.
    Abstract:
    The closed insulated pallet system (CIPS) was evaluated for growth, yield, and fruit quality of tomato genotypes with determinate growth habit. Plants were irrigated with several levels of sodium chloride (NaCl) salinized water. Tomato growth and yield were significantly greater in CIPS than in conventional surface-irrigated containers, regardless of irrigation...

  • Genotype-environment interaction in winter wheat F₁ progeny

    Creator:
    Peterson, C. J.
    Abstract:
    Seven winter wheats were evaluated for plant height, the components of yield and yield in a diallel cross at Pendleton, Oregon and Lind, Washington. An additional parent was added to the diallel cross at Pullman, Washington. Two levels of nitrogen and five replications were utilized at each of the locations....

  • Enhancement of cold tolerance in tomato plants by genetic engineering of glycinebetaine biosynthesis

    Creator:
    Park, Eung-Jun
    Abstract:
    Tomato [Lycopersicon esculentum Mill.] plants are chilling sensitive and do not naturally accumulate glycinebetaine (GB), a metabolite that functions as a stress protectant in plants. While GB can increase tolerance of tomato plants to salt and drought stresses, its effect on chilling tolerance has not been examined. To evaluate whether...

  • Auxin and cytokinin interaction in tomato (Lycopersicon esculentum Mill.)

    Creator:
    Coenen, Catharina
    Abstract:
    The phytohormones auxin and cytokinin control plant development through a complex network of interactions which include synergistic, additive, and opposite effects whose mechanisms are unknown. The auxin-insensitive diageotropica (dgt) mutant provided a tool to dissect the relationship between auxin- and cytokinin-induced responses in tomato. Morphological, physiological, and molecular data support...

  • Breeding qualitative and quantitative traits for potatoes in the Columbia Basin

    Creator:
    Graebner, Ryan C.
    Abstract:
    The cultivated potato (Solanum tuberosum L.) is one of the world’s most important staple crops, ranked fourth after maize, rice, and wheat. While the potato’s success is due largely to its high yield, it also benefits from its broad global acceptance, and its ability to be used by the consumer...

  • Molecular genetic analysis of fruit development in tomato (Lycopersicon esculentum, Mill.)

    Creator:
    Balbi, Virginia
    Abstract:
    Plant hormones regulate progression through the different phases of plant development in response to endogenous and environmental cues. Gene expression studies, as well as genetic and molecular analysis of mutants with altered hormonal responses, are two common approaches to elucidate hormone response pathways. This dissertation compares ovary and fruit development...

  • The evaluation of heterosis for grain yield, total leaf area and malting quality in 21 spring barley crosses

    Creator:
    Carleton, A. E. (Albert Eugene), 1940-
    Abstract:
    The purpose of this study was to determine the amount of heterosis in three complex traits in barley and to investigate the concept of component interaction as a means of producing heterosis. The complex traits were grain yield, total leaf area, and malting quality. Seven varieties of spring barley were...
