Research Project: Determining allelopathy in cereal rye breeding lines

Location: Dairy Forage Research

Project Number: 5090-21500-002-073-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 1, 2026
End Date: Aug 31, 2029

Objective:
Perform a counter-season winter nursery screening to determine allelopathic potential of rye genotypes and varieties. Deliver data prior to heading date of rye in northern nurseries.

Approach:
Cooperator will perform a counter-season winter nursery screening to determine which genotypes of rye are damaging to cash crops like alfalfa and vegetables, and which genotypes are helpful for weed control ahead of soybeans. The data collected will inform selection of best genotypes in cereal rye nurseries in Wisconsin, New York, and Minnesota for forage use and weed control.
