Introgression of clubroot resistance from B. oleracea into B. napus and study the inheritance of the resistance
DownloadFall 2023
Clubroot disease, caused by Plasmodiophora brassicae, is one of the most devastating threats to Brassica napus canola production worldwide. Growing clubroot-resistant cultivars is considered the most efficient way of managing this disease. All available clubroot-resistant canola cultivars carry...

Disentangling a freshwater amphipod–acanthocephalan system from ecological and molecular perspectives
DownloadSpring 2019
One of the major goals in ecological research is to understand factors that influence distribution, diversity and prevalence of parasites and their hosts. How hosts are distributed geographically clearly restricts the spatial distribution of associated obligatory parasites. This restriction is...

Evaluation of Spring Canola (Brassica Napus) Lines Derived from Rutabaga (Brassica Napus Var. Napobrassica) X Canola Crosses for Agronomic and Seed Quality Traits and Heterosis
DownloadSpring 2018
Brassica napus L. (AACC, 2n = 38) canola is the most extensively cultivated Brassica oilseed crop in the world; it is one of the most important field crops in Canada. The narrow genetic diversity in this crop is considered one of the major hindrances for continued improvement of this crop for...

Evaluation of Genetic Diversity and Performance of the Inbred Lines Derived from B. Napus x B. Rapa Interspecific Crosses and Their Test Hybrids
DownloadSpring 2018
ABSTRACTSpring Brassica napus L. canola (AACC, 2n = 38) is the second most important crop in Canada. Genetic diversity in this crop is narrow; therefore, broadening of the genetic base of this crop is needed for continued improvement through breeding. For this, the exotic gene pools of this...

Broadening of genetic diversity in spring canola (Brassica napus L.) by use of the C genome of Brassica oleracea var. italica and Brassica oleracea var. capitata
DownloadSpring 2016
Spring canola Brassica napus L. (AACC, 2n = 38) is one of the major crops in Canada. A decline in genetic diversity in breeding populations is a threat for continued improvement of this crop from a long-term perspective. Genetic diversity in Canadian spring B. napus canola can be broadened...

Broadening of genetic diversity in spring canola (Brassica napus L.) by use of yellow sarson and Canadian spring Brassica rapa L.
DownloadFall 2015
Canada is the top producer of Brassica oilseeds [B. napus L. (n = 19, AC genome)] in the world. Genetic diversity has declined in this crop in the recent years due to use of only superior and genetically narrow gene pool in breeding. Presence of adequate genetic diversity is important for further...

Genetic variation in lodgepole pine and interior spruce: adaptation to climate and implications for seed transfer
DownloadSpring 2014
This thesis investigates genetic variation of two commercially important conifers in western Canada, interior spruce and lodgepole pine. The goals were to quantify genetic diversity and geographic structure, to describe multitrait adaptation to local climates, and to use this information for the...

The genetic signature of rapid range expansions: How dispersal, growth and invasion speed impact heterozygosity and allele surfing
Download2014-01-01
Lewis, Mark A. , Coltman, David W. , Goodsman, Devin W., Cooke, Barry
As researchers collect spatiotemporal population and genetic data in tandem, models that connect demography and dispersal to genetics are increasingly relevant. The dominant spatiotemporal model of invasion genetics is the stepping-stone model which represents a gradual range expansion in which...

Biogeographic histories and genetic diversity of western North American tree species: implications for climate change
DownloadFall 2013
Over the last two million years, the evolution of North American tree species, subspecies, and genetic varieties has taken place in a constantly changing landscape often dominated by extensive ice sheets and restricted temperate climate environments. Here, I approximately reconstruct post-glacial...

Inbreeding and Genetic Diversity in Three Imported Swine Breeds in China Using Pedigree Data
Download2013
Xue, J., Li, X. W., Zeng, Z. Y., Zhu, L., Yang, R. F., Wang, Z., Bai, L., Liu, T. F., Jiang, Y. Z., Tang, G. Q., Jiang, A. A., Lian, M. J.
The accumulation of inbreeding and the loss of genetic diversity is a potential problem in the modern swine breeds in China. Therefore, the purpose of this study was to analyze the pedigrees of Chinese Duroc (CD), Landrace (CL) and Yorkshire (CY) swine to estimate the past and current rates of...
