We developed a marker based infinitesimal model for quantitative trait analysis. In contrast to the classical infinitesimal model, we now have new information about the segregation of every individual locus of the entire genome. Under this new model, we propose that the genetic effect of an...

Analysis of genotype-environment interactions from a genome-wide survey of quantitative trait loci in a barley population
Download2010-01-01
Ham, Bangjoo, Spaner, Dean, Rahman, M. H., Yeh, F. C., Yang, Rong-Cai
The presence of genotype-environment interactions (GE) leads to the imperfect genetic correlation between the measurements of the same trait in different environments, thereby limiting the ability of plant breeders to identify superior breeding lines or best cultivars across the environments. We...

Evolutionary quantitative genetics and genomics applied to the study of sexually dimorphic traits in wild bighorn sheep (Ovis canadensis)
DownloadSpring 2011
The independent evolution of the sexes may often be constrained if male and female homologous traits share a similar genetic architecture. Thus, cross-sex genetic covariance is assumed to play a key role in the evolution of sexual dimorphism (SD) with consequent impacts on sexual selection,...

Genetic mapping and physiological characterization of water-use efficiency in barley (Hordeum vulgare L.) on the Canadian Prairies
DownloadFall 2011
Temporal or seasonal water deficit is one of the major factors limiting crop yield on the Canadian Prairies. Empirical knowledge suggests that carbon isotope discrimination (Δ13C), through its negative relationship with water-use efficiency (WUE), is a good index for selecting crop varieties...

Quantitative trait loci (QTL) mapping and doubled haploid technology for spring wheat improvement
DownloadSpring 2014
Efficiency is important in wheat breeding programs. A series of studies were conducted to determine genetic differentials, map genomic regions affecting various agronomic and quality traits in conventional and organic management systems and to improve doubled haploid (DH) technology in spring...

Quantitative trait loci and genomewide association mapping in western Canadian spring wheat (Triticum aestivum L.)
DownloadSpring 2016
Early maturity, grain yield and grain protein content are some of the important traits in western Canadian wheat breeding programs. A series of experiments were conducted to explore the genetic basis of days to heading, and maturity, plant height, grain protein, grain yield and related traits. In...

Nalaila, S., Li, C., Moore, S. S., Stothard, P., Wang, Z.
Quantitative trait loci (QTL) mapped to large chromosomal regions have limited utility as DNA markers for marker-assisted selection (MAS) and are less informative as a reference for the identification of the underlying causative quantitative trait nucleotides (QTN). The objective of this study...

A whole genome scan was conducted to identify and fine map QTL regions for ultrasound and carcass merit traits in beef cattle. A total of 465 steers and bulls, genotyped for 4592 SNPs, were analysed for 16 ultrasound and carcass merit traits using interval mapping, single marker regression and...
