Narrative
Recommended in mixtures with alfalfa for hay in regions of the Northern Great Plains where annual precipitation averages more than 350mm. Moderate to good resistance to leaf-spot and root-rot caused primarily by Cochliobolus sativus. Forage and seed yields high in regional tests, particularly in long-term tests of over 3 years. In vitro digestibility at anthesis averaged 618g kg-1. Plant height and lodging resistance were similar to other current cultivars.
