Stolon effects on growth and development of potato (Solanum tuberosum L.) nodal cuttings

Creator:: Thompson, Joyce Ann
Abstract:: Experiments were conducted to determine: (1) effects of pretransplant stolon formation on performance of potato transplants in the field and greenhouse; (2) effects of parent plant nodal position on productivity of rooted nodal cuttings; and (3) relationships between photoperiod and stolon formation. The effects of early stolon formation on Russet...

The effects of density and proportion on spring wheat and Lolium multiflorum Lam

Creator:: Concannon, Julie Ann
Abstract:: This thesis consists of four chapters. Literature is reviewed in Chapter 1. Chapter 2 describes an addition series experiment to determine the influence of species density and proportion on vegetative and reproductive yield of spring wheat and Lolium multiflorum. Chapter 3 consists of a growth analysis experiment to determine whether...

Development of Diagnostic Assays for Race Differentiation of Podosphaera macularis

Creator:: Block, Mary H.
Abstract:: Hop powdery mildew (Podosphaera macularis) was confirmed in the Pacific Northwest in 1996. Before 2012, the most common race of P. macularis was able to infect plants that possessed powdery mildew resistance based on the R-genes Rb, R3, and R5. Post 2012, two additional races of P. macularis were discovered...

Influence of phosphorous and lime application on root growth and grain yield of two winter wheat cultivars (Triticum Aestivum, L em thell)

Creator:: Boulger, Mary Caroline
Abstract:: Differential grain yield response of two winter wheat cultivars ('Yamhill' and'McDermid) when grown on acid soils prompted this investigation. Root samples were taken at two soil depths at late tillering and anthesis from plots established on an acid nonpareil soil in Douglas County, Oregon. The soil pH was 5.2-5.3 and...

Possible associations between three procedures to measure noodle starch quality in winter wheat (Triticum aestivum L.)

Creator:: Weight, Chris (Christopher Thompson)
Abstract:: Until recently, the viscoamylograph had been the primary method for measuring starch as it relates to noodle quality in wheat. This method requires a large sample of flour and is time consuming. With the introduction of the rapid visco-analyser (RVA) in 1986 and the more recent flour swelling volume procedure,...

Association of selected traits with visual selection for yield in wheat (Triticum aestivum, L. em Thell.)

Creator:: Marciniak, Michael E.
Abstract:: Visual selection for grain yield may be a limiting factor in identifying superior yielding genotypes in a breeding program. This investigation was conducted (1) to compare the effectiveness of visual selection for grain yield by three selector groups representing different levels of plant breeding experience, and (2) to examine the...

Simple sequence repeat marker development and fingerprinting in Cuphea lanceolata Ait. and C. viscosissima Jacq

Creator:: Karmarkar, Vidyadhar M.
Abstract:: Microsatellites or simple sequence repeats (SSRs) are highthroughput sequence based DNA markers that have been exploited as tools for measuring genetic distance and diversity in evolutionary studies, protection of intellectual property, genetic resource conservation management, cultivar identification and molecular breeding of crop plants. We isolated and sequenced 1095 clones from...

A comparison of vegetation suppression and sod-seeding methods using perennial ryegrass in renovation of non-irrigated permament pastures in western Oregon

Creator:: Neumeister, John H.
Abstract:: Sod-seeding techniques offer graziers a convenient way to introduce superior grass cultivars into underproductive permanent pastures. Production loss and erosion are minimized. In conjunction with improved grazing management and fertilization, renovation can significantly improve yield and quality of pastures. Existent vegetation must be suppressed prior to introducing new cultivars. This...
