The objective of the tall fescue breeding program is the development of varieties characterized by superior nutritive value (including reduced contents of perloline and loline alkaloids and the fungal endophyte, Epichloe typhina), palatability, disease resistance, and adaptation through the utilization of intergeneric and interspecific hybrid derivatives of ryegrass and tall fescue species. Varieties previously released from the breeding program were, Kentucky 31, Kenwell, and Kenhy. Johnstone tall fescue, developed cooperatively by the Kentucky Agricultural Experiment Station and USDA-ARS, was released March 1, 1982, as,a new variety. Johnstone is characterized as having low levels of perloline alkaloid and the fungal endophyte, Epichloe typhina, and improved forage quality during summer. It is expected that seed of Johnstone will be available commercially during 1984 or 1985.
