Interpretive Summary: Agricultural Research Service announces the release of ‘USDA-Yeti’ orchardgrass. USDA-Yeti was developed from the USDA-UTWH-102 orchardgrass germplasm. Multi-environment variety trials at three locations showed that USDA-Yeti received 10-30% less winter injury than other orchardgrass cultivars except for the Canadian cultivar AC Killarney. USDA-Yeti also produced similar to greater forage yields and stands than all the included orchardgrass cultivars. The excellent winter hardiness and agronomic performance of USDA-Yeti makes it an optimal choice for production sites that have winter injury potential.
