Crop Wild Relatives (CWR) are wild plant species that are closely related to crops. They are of great importance since traits in these wild species can be transferred to crops by traditional plant breeding approaches. In many cases, wild species have traits that are not present in modern crops, for example pest and disease resistance, tolerance to drought, waterlogging or heat stress. Such traits are very important when adapting crops to future climate conditions and diseases and are therefore central for climate change adaptation and future food security.
The Nordic network on CWR was initiated in 2015 with the long-term aim to promote a well-functioning, climate- and environmentally friendly Nordic agriculture by strengthening CWR conservation and facilitating use of CWR. The third phase of the project was initiated in 2020 with funding from NKJ (The Nordic Joint Committee for Agricultural and Food Research). Funding was granted from the Nordic Committee of Senior Officials for the Environment and Climate in December, which made it possible to expand the Nordic work on CWR during 2021-2024, and in 2023, NordGen’s CWR working group was granted additional internal funding for seed collection.
During 2023, several project activities were carried out with the goal to strengthen in situ and ex situ conservation of CWR and facilitate sustainable use. Inventories of CWR were conducted in Denmark, in areas of the nature national parks in Husby and Stråsø, a research area in Mols, and privately owned land in Kattrup. On Åland, an inventory has been carried out in 44 inventory squares within the Nåtö-Jungfruskär nature reserve. Seeds of CWR were collected in several locations in Denmark, Finland, Iceland, Norway, Sweden, and Åland. To better understand the impact of climate change on Nordic CWR, climate modelling was used to evaluate future geographic distributions under different climate scenarios. The distribution of genetic diversity was studied in selected CWR across the Nordic region using molecular markers.
