Turfgrass breeding efforts at the University of Florida have recently changed direction. The breeding program is now located at the newly developed G.C. Horn Turfgrass Field Laboratory in Citra, FL and will involve the development of both warm and cool season turfgrass cultivars. Breeding of tall fescue (Festuca arundinacea Schreb.) and perennial ryegrass (Lolium perenne L.) will primarily involve selection for summer persistence as related to rust resistance and heat tolerance in Florida's hot and humid climate. Available germplasm of warm season species at the University of Florida includes zoysiagrass (Zoysia spp. Willd.), common bermudagrass (Cynodon dactylon (L.) Pers. var. dactylon), African bermudagrass (Cynodon transvaalensis Burtt-Davy), centipedegrass (Eremochloa ophiuroides [Munro] Hack.), bahiagrass (Paspalum notatum Flugge), seashore paspalum (Paspalum vaginatum Swartz), and common carpetgrass (Axonopus affinis Chase). Other sources of these species are needed to broaden current collections and germplasm of potential alternative turfgrass species are being identified and collected. Specific objectives of the breeding program are enhanced shade tolerance; resistance to the sting, lance, and root-knot nematodes; resistance to rhizoctonia diseases; and a reduction in irrigation and fertility requirements.
