The objective of the tall fescue breeding program at the University of Kentucky is the development of varieties characterized by superior nutritive value (including reduced levels of perloline and loline alkaloids), minimal infestation of the fungal endophyte, Acremonium coenophialum), higher palatability, improved disease resistance, and wider adaptation through the derivation of intergeneric and interspecific hybrids of ryegrass and tall fescue species. Kentucky 31, Kenwell, and Kenhy were varieties released from this breeding program. Johnstone tall fescue, developed cooperatively by the Kentucky Agricultural Experiment Station and USDA-ARS, is the most recently released variety. It is characterized as having low levels of perloline alkaloid and the fungal endophyte (Acremonium coenophialum) and improved forage quality during summer. Ample Johnstone seed should be available to meet demand during 1986.
