Quantitative trait loci mapping for grain yield and other traits of agronomic importance in maize
Several marker loci were associated with more than one trait. Thus genes controlling these traits may map to the same chromosomal regions or have pleiotropic effects. Although a number of marker loci were associated with genotype by environment interactions (GXE) for grain yield among individual …

Genomic selection and quantitative trait loci mapping for Fusarium head blight resistance in wheat (Triticum aestivum L.)
… calculate breeding values for wheat lines, for traits related to resistance disease. In the first study of this dissertation, genomic selection (GS) models were compared for predicting traits associated with resistance to FHB resistance, using 273 breeding lines in use at the University of …

Quantitative trait loci mapping for agronomic and fiber quality traits in Upland cotton (Gossypium hirsutum L.) using molecular markers
… to the breeder. The understanding of the quantitative trait loci (QTL) contributing to agronomic and fiber quality traits offers an excellent route to solve this problem. A QTL analysis was carried out after an F<sub>2:3</sub> population composed of 138 lines, derived from the …

The Genetic Basis of Susceptibility to Therapy-related Leukemia in Mice
… numbers. In addition to the susceptible strains, quantitative trait loci mapping was used on the initial study to identify genetic components responsible for the leukemic phenotype. This analysis revealed two significant peaks of interest on chromosomes 3 and 14. The 1 Mb region on chromosome 3 …

QTL discovery for Japanese beetle resistance in aphid-resistant germplasm, stacking aphid-resistant genes, and metabolite profiling studies in soybean
… lower susceptibility to Japanese beetle. A QTL (Quantitative Trait Loci) mapping approach with a subset of 94 individuals on 15 chromosomes indicated the presence of five QTL (QTL-M, QTL-G, QTL-H, QTL-D1b and QTL-E) previously reported to confer resistance to several other soybean defoliators, …

Simple sequence repeat polymorphism screening for resistance to Cercospora Arachidila in groundnut(Arachis Hypogaea)Genotypes
… preferred characteristics and other quality traits. The tediousness of handling a self pollinating species in gene introgression by interspecific hybridisation and the general mode of inheritance to disease resistance complicates the transfer of resistance. Resistance is a low heritability …

The Maintenance of Genetic Variation by Environmental Selection
… greenhouse experiments to identify key traits responsible for the EAST-WEST local adaptation, and that those traits have significantly larger differentiation between subspecies than neutral expectation. In Chapter 5, I performed quantitative trait loci mapping for those important traits …

THE ECOLOGICAL IMPORTANCE AND EVOLUTIONARY POTENTIAL OF PHENOTYPIC PLASTICITY IN NOVEL ENVIRONMENTS
… in phenotypic plasticity in a functional trait, alcohol dehydrogenase, and its effect on larval survival of Drosophila melanogaster in a novel alcohol environment. After a population colonizes a novel environment, the population often adapts to this new environment, and phenotypic …

Genetic Control of Survival and Weight Loss during Pneumonic Burkholderia pseudomallei (Bp) Infection
… data to identify that survival is a complex trait involving loci on chromosomes 5 and 7 and weight retention involves loci on chromosome 12. We then analyzed and ranked several potential candidate genes within the significant and/or suggestive interval on these chromosomes that appear to …
