Breeding Snap Beans for Organic Agriculture: Quantification and Application of Key Traits

Creator:: Park, Hayley E.
Abstract:: Improving crop cultivars for use on organic farms is pertinent, as current elite germplasm is less resilient within the more variable context of organic farm environments. Although a growing number of studies have focused on organic plant breeding in cereal crops, very few have focused on vegetable crops, especially those...

Quantitative Trait Loci and Genome Wide Association Study for Resistance to White Mold in Common (Snap) Bean.

Creator:: Arkwazee, Haidar A.
Abstract:: This is a Ph.D. dissertation for a study conducted at OSU/Horticulture. The main objective of this study was dissecting the genetic background for white mold resistance in common (snap) bean. Tow main approaches were followed to achieve the goal. The first approach was using the classical quantitative trait loci (QTL)...

Traditional and molecular approaches to Zucchini yellow mosaic virus resistance in Cucurbita

Creator:: Brown, Rebecca Nelson
Abstract:: Zucchini yellow mosaic virus (ZYMV) is an important disease of Cucurbita worldwide. Resistant cultivars are the best means of control. ZYMV resistance is quantitative in the wild species C. ecuadorensis, and is controlled by at least three genes in tropical C moschata. Very little molecular work has been done in...

Serial manure amendments : effects on soil properties and root rot of sweet corn

Creator:: Cox, Bonnie S. Hoffman
Abstract:: The effect of serial (multiple-year) organic matter (OM) amendment on soil properties has been described in some cropping systems, although less is known about the effect of serially amended field soils on soil-borne plant diseases. The objectives of this study were to describe the effects of the third and fourth...

Nutrient Profile and Nursery Feeding Damage of Halyomorpha halys (Hempitera: Pentatomidae)

Creator:: Skillman, Victoria P.
Abstract:: Halyomorpha halys Stål, brown marmorated stink bug or BMSB, is now present in 43 US states. A native of eastern Asia, this pest can feed on ~200 different plant species damaging bark, leaves, buds, stems, and fruits. Many of these plant species include wild plants, ornamentals, and agricultural crops. BMSB...

Winter Squash: Production and Storage of a Late Winter Local Food

Creator:: Wetzel, Jennifer D.
Abstract:: Winter squash is an important late winter vegetable crop for local and regional markets; however, farmers in western Oregon report that this crop is marginally profitable due to losses in storage and relatively low yields for the high culinary value kabocha and buttercup types. In order to increase the sales...

High-density Linkage Maps for European Hazelnut (Corylus avellana L.) from Single Nucleotide Polymorphism Markers and Mapping New Sources of Resistance to Eastern Filbert Blight

Creator:: Komaei Koma, Golnaz
Abstract:: European hazelnut (Corylus avellana L.) is a diploid with 11 pairs of chromosomes (2n = 2x = 22), monoecious, dichogamous and wind-pollinated. Eastern filbert blight (EFB) caused by Anisogramma anomala is a serious disease of European hazelnut (Corylus avellana) in North America, and infection leads to cankers that girdle branches...

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...

The effect of bud self pollination, open flower self pollination, and cross pollination on the field characteristics of broccoli progenies

Creator:: Yin, Yun-Fu
Abstract:: To determine the effect of bud pollination, compared to pollination of open flowers and crossing, on field characteristics of broccoli progenies, an experiment was conducted in 1974 and 1975 at Corvallis, Oregon. Single plants of 55 broccoli lines were pollinated, using four methods, i.e. bud pollination (BP), open flower pollination...

Novel methods for crop load management of pear cultivars in the Pacific Northwest

Creator:: Arrington, Matthew A.
Abstract:: Novel approaches to crop load management of pear orchards in the Pacific Northwest (PNW) are necessary, but will need to vary according to the unique vegetative and reproductive growth habits of the cultivar. 'D'Anjou' is vigorous and non-precocious; thus, strategies to limit vigor and induce early fruiting are required. In...
