Crop Wild Relatives of the United States

a blog about their conservation and use


Crop curators, researchers and plant breeders- your input is vital!

Our sincere thanks to the dozens of genebank crop curators, plant breeders, and research scientists who submitted their inputs on the national inventory1 and the crop genepool priorities identified within the inventory. These inputs were invaluable particularly in identifying priority non-food crop genepools (e.g. medicinals, ornamentals, and forestry species) as well as highlighting specific non-native or distantly related crop wild relative (CWR) taxa that represent priorities for utilization. With these inputs we have been able to collaboratively produce a list of priority CWR as the foundation for a conservation strategy for CWR of the U.S., and to identify those crop genepools that will require future consideration.

Phaseolus acutifolius

We are currently gathering occurrence data for taxa from the priority genepools. Your contribution of occurrence datasets for U.S. distributions of these taxa will improve the results of the analysis. Please contact us if you have experience in the distribution and conservation status of particular genera/taxa, have datasets to share, and/or would be interested in examining results and contributing comments.
