TEACHING 

	I taught one-third of AGR 510 (Forage Ecology) during the spring 1993 semester 
(covering topics of morphology, anatomy, taxonomy and breeding of forage grasses and 
legumes).  I guest-lectured in several classes during the spring 1994 semester (AGR 510, AGR 
676, AGR 664) and fall 1994 (AGR 386).  In the fall semester of 1995, I taught PLS 386, Plant 
Production Systems, a four-hour course.  The class had 14 students with two 75 minute lectures 
per week as well as two lab sections.  I co-teach this course with Dr. Jack Buxton (Horticulture). 
 The fall 1996 semester has about 50 students enrolled.

NARRATIVE STATEMENT

The Tall Fescue Genetics and Breeding Research Program
Department of Agronomy, University of Kentucky
	Tall fescue is the most important cool-season forage grass in the Southeastern U.S. 
occupying approximately 30 million acres.  In Kentucky, more than five million acres of tall 
fescue contribute immensely to forage and livestock production.  The presence of an 
endophytic fungus in most of the existing tall fescue pastures and the associated problems with 
"fescue toxicosis" require continued efforts by tall fescue breeders and related scientists.  The 
tall fescue geneticist in the Department of Agronomy is part of a multidisciplinary team of 
forage researchers.  Interactions among scientists in the department specializing in forage/hay 
quality, alkaloid composition, and forage utilization will allow the fescue breeder to make 
significant contributions in the improvement of forages in Kentucky and in the region.  
	To meet the needs of farmers, endophyte-free tall fescue cultivars are being developed 
with improved seedling vigor, persistence, yield, and forage quality.  Over the past four and a 
half years, we have established over 120,000 space-planted tall fescue plants as source 
nurseries.  These plants represent the USDA's PI collection of 562 tall fescue accessions as 
well as commercial varieties including Johnstone, Kenhy and Kentucky 31.  Other sources of 
parental tall fescue germplasm include collections from endophyte-free tall fescue pastures in 
Kentucky.  During the fall of 1992, I sampled ten pastures and have identified several hundred 
persistent (8-12 years old) endophyte-free genotypes from Kenhy, Johnstone and KY 31 
pastures that had grazing pressure.  Nearly 5000 F1 hybrids of tall fescue and ryegrass have 
been treated with colchicine to restore fertility and allow the transfer of forage quality from 
ryegrass into tall fescue. Twenty replicated field trials of various tall fescue material and other 
cool season forage grasses have been established to date.  Novel approaches to the production 
of amphiploids are being tested and include the use of nitrous oxide and antitubulin herbicides  
in tissue culture.
	I have assembled equipment and tested protocols for a molecular marker plant breeding 
laboratory.  Isozymes and RAPDs are two types of markers that are being used to study the 
genetics of tall fescue with the ultimate aim of finding markers linked to forage quality, disease 
resistance, yield and seedling vigor traits.  In addition to the molecular marker/genetics lab, we 
have begun to study seedling vigor in tall fescue.  
	In the greenhouse and in the field, over 5000 hybrid crosses were made during March 
1993-June 1996.  Approximately 50 polycross populations are being evaluated for potential 
release as new varieties.  Within the next year, germplasm and variety releases are anticipated 
for orchardgrass and timothy.  Selections were made in `Boone' orchardgrass for improved 
disease resistance, later maturity, and greater forage  and seed yields.  Selections from `Clair' 
timothy were made for leafiness and earlier maturity.  These populations have been advanced 
through another cycle of selection.  Currently we are evaluating 32 new experimental tall fescue 
synthetics for their suitability as improved forage cultivars.  During 1995, we began to use cattle 
in selecting palatable, persistent tall fescue genotypes.  Other areas of research include surface 
mine reclamation with cool season forage grasses, selection of tall fescue with greater ease of 
grazing (grinding resistance, leaf tensile strength), and endophyte interactions with specific tall 
fescue genotypes.
