They play a major role in providing high quality roughage for the economical production of meat, milk and fiber products, and are important in soil conservation and environmental protection. Besides being used as forage, some of the grasses are grown specifically for turf or amenity purposes on sports fields, golf courses, parks, lawns and roadsides. Turf grasses contribute considerably to our environment by adding beauty to the surroundings, providing a safe playing surface for sports and recreation, and preventing erosion. Genetic improvement is one of the most effective ways to increase productivity of forage and turf. Due to the biological complexity of forage and turf species and the associated difficulties encountered by traditional breeding methods, the potential of molecular breeding for the development of improved cultivars is evident. The joint efforts of molecular biologists, plant breeders and scientists in related disciplines will make the available biotechnological methods useful for accelerating forage and turf improvement. The 3rd International Symposium on Molecular Breeding of Forage and Turf was held May 18-22, 2003, in Dallas, Texas and Ardmore, Oklahoma. The Conference was hosted by The Samuel Roberts Noble Foundation in cooperation with Texas A&M University. Attendees included breeders, molecular biologists, geneticists, agronomists and biochemists from sixteen countries. The program featured plenary addresses from leading international speakers, selected oral presentations, volunteered poster presentations, as well as tours of the Noble Foundation in Ardmore, Oklahoma, and the Texas A&M Agricultural Research and Extension Center in Dallas. This book includes papers from the plenary lectures and selected oral presentations of the Conference. A wide variety of themes are included and a collection of authoritative reports provided on the recent progress and understanding of molecular technologies and their application in plant improvement. Almost all relevant areas in molecular breeding of forage and turf, from gene discovery to the development of improved cultivars, are discussed in the proceedings. The 3rd International Symposium on Molecular Breeding of Forage and Turf and the publication of this volume, Molecular Breeding of Forage and Turf, have been supported by the Noble Foundation, Texas A&M University, National Science Foundation, USDA-ARS, U.S. Golf Association, Texas xi xii Turfgrass Association, Controlled Environments Ltd. (Conviron), PhytoTechnology Laboratories L.L.C., The Scotts Co., Qiagen Inc., Monsanto Co., Forage and Grassland Foundation, Grass Breeders Conference, American Forage and Grassland Council, Crop Science Society of America and North American Alfalfa Improvement Conference. We express our sincere thanks for their sponsorship and support. We thank Mervyn Humphreys, Odd Arne Rognli, German Spangenberg and Hotoshi Nakagawa of the International Organizing Committee, as well as Milt Engelke, Mark Hussey, Shan Ingram, LIoyd Sumner and Brian Unruh of the Local Organizing Committee for their contributions to the success of the conference.
