Using a barley Nested Association Mapping (NAM) Population to mine wild barley germplasm for crop improvement
Modern cultivar barley, like other cultivated cereals, went through the so called “domestication syndrome”, by which early farmers subjected the crop to a consistent selection that led to gradual changes in its characteristics and architecture. The result is that the modern cultivar differs from …

Assessing wild barley germplasm in multiparent and advanced backcross populations for mapping, gene discovery, and improvement of malting barley
Wild barley (Hordeum vulgare ssp. spontaneum), the progenitor of cultivated barley (Hordeum vulgare ssp. vulgare), is a rich source of genetic diversity. This diversity is not easily exploited due to challenges inherent in identifying and extracting beneficial alleles from widely unadapted …

Comparative analyses identify adaptive genetic variation in crops and crop wild relatives
… variants in the genomes of crops and crop wild relatives. These approaches have the potential to identify genetic variants that are under selection and thus potentially contributing to local adaptation. As a background to the dissertation, I present in Chapter 1 the state of research in …

An Investigation of Seed Longevity and Antioxidant Changes of Conserved Barley Germplasm
… conducted to predict the longevity of a diverse barley (Hordeum vulgare L.) germplasm collection comprising cultivated and wild types preserved in long-term storage (LTS) at Plant Gene Resources of Canada (PGRC) for 5 to 37 years, and to study the changes in antioxidant levels during storage. In …

Recombinant Chromosome Substitution Lines as a Source of Genetic Variation for Drought Stress Tolerance in Barley
… the naturally occurring genetic variation of the wild barley genepool has become a major target of barley crop breeding programmes aiming to increase crop productivity and sustainability in global climate change scenarios. However this diversity remains unexploited and effective approaches are …
