About
Crop Wild Relatives

Crop wild relatives are the wild cousins of our cultivated crops.

They are related to the foods we eat and can contain useful traits which can help us make our crops more resilient to climate change.

What are crop wild relatives

Sharing CWR

Many crop wild relatives held in public collections around the world are available for use in research and breeding through the framework of the International Treaty on Plant Genetic Resources for Food and Agriculture.

The International Treaty promotes the exchange of crop diversity and ensures that the benefits of its use are shared fairly and equitably.
