Genetic diversity and population structure of an important wild berry crop
(Journal article; Peer reviewed, 2015)The success of plant breeding in the coming years will be associated with access to new sources of variation, which will include landraces and wild relatives of crop species. In order to access the reservoir of favourable ... -
Genetic evidence of female kin clusters in a continuous population of a solitary carnivore, the Eurasian lynx
(Journal article; Peer reviewed, 2018)Large terrestrial carnivores can sometimes display strong family bonds affecting the spatial distribution of related individuals. We studied the spatial genetic relatedness and family structure of female Eurasian lynx, ... -
Genetic Identity and Diversity of Apple Accessions within a Candidate Collection for the Norwegian National Clonal Germplasm Repository
(Peer reviewed; Journal article, 2022-07-12)In order to best conserve, as well as utilize, traditional apple germplasm in Norway, an apple heritage cultivar collection was established in Ullensvang, western Norway, which aims to become the National Clonal Germplasm ... -
Genetic mapping and identification of a QTL determining tolerance to freezing stress in Fragaria vesca L.
(Peer reviewed; Journal article, 2021-05-21)Extreme cold and frost cause significant stress to plants which can potentially be lethal. Low temperature freezing stress can cause significant and irreversible damage to plant cells and can induce physiological and ... -
Genetic mapping using a wheat multi-founder population reveals a locus on chromosome 2A controlling resistance to both leaf and glume blotch caused by the necrotrophic fungal pathogen Parastagonospora nodorum
(Peer reviewed; Journal article, 2020-01-29)Key message A locus on wheat chromosome 2A was found to control feld resistance to both leaf and glume blotch caused by the necrotrophic fungal pathogen Parastagonospora nodorum. Abstract The necrotrophic fungal pathogen ... -
Genetic markers identify duplicates in Nordic potato collections
(Peer reviewed; Journal article, 2024-08-26)Introduction: The first small scale cultivation of potatoes in the Nordic countries began roughly 300 years ago, and later became an important staple food in the region. Organized conservation efforts began in the 1980s, ... -
Genetic population structure of the monogenean parasite Gyrodactylus thymalli and its host European grayling (Thymallus thymallus) in a large Norwegian lake
(Peer reviewed; Journal article, 2020-10-15)Understanding how populations are structured in space and time is a central question in evolutionary biology. Parasites and their hosts are assumed to evolve together, however, detailed understanding of mechanisms leading ... -
Genetic Structure of the Norwegian Parastagonospora nodorum Population
(Peer reviewed; Journal article, 2020-06-16)The necrotrophic fungal pathogen Parastagonospora nodorum causes Septoria nodorum blotch (SNB), which is one of the dominating leaf blotch diseases of wheat in Norway. A total of 165 P. nodorum isolates were collected from ... -
Genetic studies of fall armyworm indicate a new introduction into Africa and identify limits to its migratory behavior
(Peer reviewed; Journal article, 2022-02-04)The fall armyworm, Spodoptera frugiperda (J.E. Smith) is native to the Americas and a major pest of corn and several other crops of economic importance. The species has characteristics that make it of particular concern ... -
Genetic substructure and admixture as important factors in linkage disequilibrium-based estimation of effective number of breeders in recovering wildlife populations
(Journal article; Peer reviewed, 2017)The number of effective breeders (Nb) and effective population size (Ne) are population parameters reflective of evolutionary potential, susceptibility to stochasticity, and viability. We have estimated these parameters ... -
Genetic yield gains of winter wheat in Germany over more than 100 years (1895-2007) under contrasting fertilizer applications
(Journal article; Peer reviewed, 2018-09-27)For highly productive regions such as Germany, the increase of wheat grain yields observed throughout the 20th century is largely attributed to the progress in crop breeding and agronomic management. However, several studies ... -
