Research Project: Evaluation of Orchardgrass Varieties and Germplasm for Tolerance Or Resistance to the Choke Causing Fungus Epichloe Typhina

Location: Forage and Range Research

Project Number: 2080-21000-014-15
Project Type: Nonfunded Cooperative Agreement

Start Date: May 01, 2012
End Date: Sep 30, 2015

Objective:
The objective of this cooperative research project is to determine if there is heritable variation among diverse orchardgrass entries for choke infection and resistance.

Approach:
Collaborative field research will occur in sites in the Willamette Valley in western Oregon, including the research farm of Barenburg USA, other orchardgrass seed growers in the Corvallis area, and the Oregon State University Hyslop Research Farm. Seedling germination and preparation, and studies using greenhouse and laboratory work, will occur in the USDA-ARS FRRL location in Logan, UT. Plants will be maintained for three years, whereupon the choke infection will be visually assessed and seed harvest taken.
