Cereal production in important growing regions is negatively influenced by climate change. This can be countered by expanding cereal production northwards in Scandinavia and Iceland, where today barley is primarily used as feed, rarely reaching malting quality. This study explores genetic factors underlying the ability of barley to mature fully in...
Various fungal species continue to be one of the most difficult challenges faced by farmers, and hence societies in whole, when it comes to securing plentiful and wholesome food for a rapidly growing human population. Understanding the biology of pathogenic fungi in detail, both at the population and molecular levels, combined with continued emphas...
Genome-Wide Association Studies (GWAS) of four Multi-parent Advanced Generation Inter-Cross (MAGIC) populations identified nine regions on chromosomes 1H, 3H, 4H, 5H, 6H and 7H associated with resistance against barley scald disease. Three of these regions are putatively novel resistance Quantitative Trait Loci (QTL). Barley scald is caused by Rhyn...
Icelandic barley genotypes have shown extreme earliness both in flowering and maturity compared to other north European genotypes, whereas earliness is a key trait in adapting barley to northern latitudes. Four genes were partially re-sequenced, which are Ppd-H1, HvCEN, HvELF3, and HvFT1, to better understand the mechanisms underlying this observed...
The causal agent of the barley net blotch disease, Pyrenophora teres , is known for its high level of diversity due to sexual reproduction. Different pathotypes, defined by a virulence combination, even within the same fields are frequently found and virulence between locations can vary considerably. Evaluation of virulence patterns of a pathogen p...
The northwards expansion of barley production requires adaptation to longer days, lower temperatures and stronger winds during the growing season. We have screened 169 lines of the current barley breeding gene pool in the Nordic region with regards to heading, maturity, height, and lodging under different environmental conditions in nineteen field...
The woodland strawberry, Fragaria vesca, holds great promise as a model organism. It not only represents the important Rosaceae family that includes economically important species such as apples, pears, peaches and roses, but it also complements the well-known model organism Arabidopsis thaliana in key areas such as perennial life cycle and the dev...

Barley is of great importance in modern agriculture and is currently the fourth most important cereal after wheat, maize, and rice. It is well adapted to a range of climatic and day-length conditions, with a distribution from Ethiopia to northern Scandinavia. Despite this, Iceland, with its sub-arctic agriculture, is considered to be at the margin...
Caraway (Carum carvi) is used as a vegetable; more commonly, the fruits are used to flavour foods or as a preservative. Quality is a key issue; however, little is known about the respective influences of type of material and location and the interaction of these factors on essential oil composition. In this study, wild populations and commercial cu...
The International Treaty on Plant Genetic Resources for Food and Agriculture entered into force in 2004 and is an important instrument by which plant breeders can access crop genetic diversity on the basis of multilateral “facilitated access”. To test how well access works, we sent seed requests to 121 countries that are Contracting Parties to the...
Studies of genetic diversity are a prerequisite for any plant breeding programme. Where the primary breeding aims are to combine yield and survival it is important to be able to identify traits associated with these two factors. We compared genetic diversity in bred cultivars of white clover of Nordic origin with that in semi-natural and natural po...

Project (1)
The main goal for the project ”Combining Knowledge from Field and from Laboratory for Prebreeding in Barley II” is to lay the foundation for effective cereal breeding for disease resistance and harvest stability in changing climate conditions capable to meet current and future challenges in the Nordic region.
The project is a Nordic collaboration between four plant breeding entities (Boreal Plant Breeding, Finland; Graminor, Norway; Nordic Seed, Denmark; Sejet Planteforædling, Denmark) and three academic institutions (LBHI, Iceland; Luke, Finland; SLU, Sweden) in pre-breeding in Barley initiated by The Nordic Council of Ministers.
