About the network
Our nationwide team aims to breed and release improved cover crop varieties by:
Advancing cover crop genetics using traditional breeding, marker-assisted selection, high-throughput phenotyping, genome sequencing, and multi-environment trials;
Engaging farmers through surveys to identify breeding targets, facilitating on-farm selection, and conducting participatory variety testing to select lines for release;
Multi-environment testing of advanced breeding lines at over a dozen nationwide sites (including USDA-NRCS-PMCs) to identify what varieties perform best in specific regions.
