Application of molecular markers to early generation testing in maize breeding
Early generation testing is used to develop improved maize (Zea mays L.) inbreds. Even though the expected genetic correlations between testcross performance in different generations is high, non-genetic effects reduce the effectiveness of early-generation testing. This experiment was conducted to …

Early-generation bulk testing in soybean and inheritance of dwarfness from soybean strain T281
… has produced mixed results on the use of early-generation bulks to measure population performance in soybean (Glycine max (L.) Merr.). The objective of our first study was to further examine the use of early-generation bulk or midparent performance to select among populations within a …

Development of New and Alternative Resources for Breeding Low Phytate Soybeans
… individuals with the desired LP trait during early generation population development, making improvement of agronomic performance among LP lines difficult. Thus, development of resources for improved phenotyping, genotyping, and early generation population development will facilitate the …

Incorporating molecular markers into applied maize breeding
… marker assisted selection (MAS) and conventional early generation testcross selection.

Bighead and silver carp hybridization in the Mississippi River Basin: prevalence, distribution, and post-zygotic selection
… their native range in eastern Asia, form multi-generational hybrids within the Mississippi River Basin (MRB). My dissertation explores the complexity and structure of bighead and silver carp hybridization in the MRB through molecular marker development, implementing those markers to test for the …

Simultaneous Mapping and Pyramiding of Fusarium Head Blight Resistance Loci in Wheat Breeding Populations
… linkage analysis of general pedigrees to early generation wheat breeding populations for development of dense framework linkage maps. Using this approach, a linkage map consisting of 3,807 loci was developed. The linkage maps showed high concordance with the SNP consensus map for wheat. …

Statistical methods and models for analyzing sugarcane (Saccharum species hybrids) plant breeding data
Early generation selection of sugarcane families using means is inadequate while visual seedling selection is subjective and inefficient. Data from advanced variety trials (yield, quality and agronomic traits) are collected over several crop-years to determine yield potential and ratooning ability …

Structural performance of early 20th century masonry high rise buildings
Early generation high rise buildings built between 1890 and World War 11 represent a technical transition between traditional load bearing masonry construction and modern curtain wall systems, and are typically referred to as 'transitional masonry buildings'. These structures comprise a large …

A Human-Centered Framework for Oncological Healthcare System Modeling Applied to Mobile Radiation Delivery
… the Theory of Planned Behavior. Finally, an early-generation system model based on an agent-based modeling approach was developed with the survey responses as input data. It also made use of publicly available regional health data to create a more generalizable approach. As a proof of concept …

Improving Genetic Analysis with Augmented Experimental Designs
… Data from a genetic mapping study in cotton and early generation trial in spring wheat were used to demonstrate the use of proposed models. With the use of generalized lattice model, the residual variance was reduced approximately by 65% for seed and lint yields in cotton and consequently, the …

White Blinders: A Study of Race Relations Theory in Britain, 1948–1988
<p>This dissertation studies the early generation of scholars who developed the academic field of race relations in Britain from the 1940s into the 1980s. The research and methodology performed throughout this period was both innovative and problematic due to the approaches taken. Early scholars, …

Improving C4 photosynthetic chilling tolerance in bioenergy crops: the search for elite breeding materials
… (0–12° C) and overnight frosts associated with early-season days in high latitudes. In chapter 2, two species from the Miscanthus genus are evaluated for their tolerance of severe chilling and overnight frost in the first comprehensive screening of a Siberian Miscanthus sacchariflorus germplasm …

Effects of selective genetic introgression from wild soybean to soybean
… 82. Family selection beginning in the F2 generation was used to develop lines from PI 507807 and PI 549046. The lines from PI 479767 and PI 483461 were selected by early generation testing through yield testing F2 lines in the F3 and F4 generation. The lines derived from PI 65549 were …

Comparative and population genomic analyses of the parasitic blood flukes
… populations, focusing on the incidence of early generation hybrids between S. bovis and S. curassoni. In the following chapter I present the results of a long-term genome assembly project, aiming to produce genome assemblies and annotations for Schistosoma and other parasitic flatworms. …

The role of aqueous-phase oxidation in the formation of highly-oxidized organic aerosol
… likely due to differences in partitioning of early-generation products. Finally, OA is formed from the gas-phase ozonolysis of biogenic precursors in the presence of reactive aqueous particles, showing that oxidation within the condensed phase can generate highly oxidized products. The overall …

Emirati women journalists bargaining with patriarchy in search of equality
… the latter, journalists were divided into two generational groups: journalists who belong to ‘the early generation’, between the ages of 30 and 60, who practised journalism from the 1970s to the 1990s; and journalists who belong to ‘the new generation’, who are in their 20s, and started …

Effects of Cereal Cyst Nematode Infection on Resistant and Susceptible Barley
… that affect plant-water relations and imposes early stress that reduces yield irrespective of the availability of water and nutrient. Invasion, migration, feeding site formation, and feeding by this nematode alter host root anatomy and interfere with water and nutrient transport in the plant. …

The Development of Divinyl-Heteroaryl Linkers for the Synthesis of Stable and Functional Antibody-Drug Conjugates
… and overall pharmacological profiles over early generation ADCs. In particular, advances in linkage strategies through antibody engineering or enzymatic modification have yielded homogeneous ADC products with defined modification sites and stable linkages. Despite significant advances in …
