Technical Abstract: The objective of this research is to determine the stress tolerance, seed productivity and forage productivity of an endophyte free (non toxic), experimental tall fescue population generated by a gamete selection approach. This approach has successfully been applied in breeding of other crop species, but has not been attempted in tall fescue. Selection for tolerance to stress and drought were applied during the approach. In addition, enhanced heterosis and hybrid vigor, generated by crossing selected lines is anticipated. Seed harvested from this plot will be recycled through the selection process. The end result of this research is the expectation of a productive; highly stress tolerant tall fescue cultivar. 2009, 2010, 2011 Forage Performance trials conducted with the USDA-ARS and Barenbrug Seeds, Inc., in Oklahoma, Alabama, Oregon and Australia indicate this material has wide adaptation and competitive performance to commercial tall fescue checks containing both novel and traditional endophytes.
