The main role of grasses, clovers and alfalfa in temperate agriculture is still to provide forage for ruminant animals but, in the last decades, the importance of amenity grasses increased markedly and, in the near future, new developments in the areas of energy and biomass use can be envisaged. Fodder Crops and Amenity Grasses, fifth volume in the series, Handbook of Plant Breeding, covers all these aspects.
Most fodder crops and amenity grasses are perennials and many of them are natural or induced polyploids. Thus, breeding procedures and strategies differ greatly from breeding annual field crops. Breeding objectives are more difficult to define in forage crops because direct measurement of the efficiency of animal production during breeding and variety assessment is impractical. As a result, a large number of selection criteria have been developed for the particular crops. However, breeding objectives and methodology have a common basis among these species and are therefore presented in the general chapters. Particular emphasis is placed on the breeding methodology for cross-pollinating species because the large majority of crops belong to this group. In addition, the potential of new molecular techniques to complement breeding concepts and strategies is presented and critically discussed.
Special techniques and procedures as well as particular breeding goals will be included in the crop specific chapters. Amenity grass breeding has its own breeding objectives and testing procedures, however, the species are mostly the same as in forage grass breeding, and crop specific chapters will include the amenity aspects where appropriate. The crop specific chapters will cover the range of topics given in the guidelines below.
The volume on Fodder Crops and Amenity Grasses is the fifth volume in series Handbook of Plant Breeding after the initial volumes on Vegetables, Cereals, Oil Crops and Fruits. Like the other volumes in the series, the volume presents information on the latest scientific information in applied plant breeding using the current advances in the field, from efficient use of genetic resources to impact of biotechnology in plant breeding. Outstanding scientists from all over the world have contributed chapters to the work.
Grassland farming in Europe was already established during the settlement of the rst farmers together with their domesticated animals after the last ice age. Since then, grassland provides the forage basis to feed ruminant animals for the p- duction of meat and milk. Depending on the ecological conditions and intensity of usage, various plant communities with different species developed, displaying a rich biodiversity. With the introduction of improved crop rotations at the end of the 16th century, grasses and legumes were also grown to an important extent as forage crops on arable land. In the last decades the importance of amenity grasses increased markedly, due to the demand of the society for new usages like landscape protection. Around 1900 interested farmers and academics identi ed the need for gra- land improvement through systematic selection and seed production. This marks the beginning of breeding and research in companies but also at universities and specialized research institutes. Plant collection started with many of the species that are still of importance today. The collected materials were grouped according to the intended use and some type of phenotypic selection was applied. Seed mul- plication of such populations was performed in pure stands and the harvested seed was marketed. Although the vegetative biomass and its quality are of utmost imp- tance in forage crop breeding, it is the seed yield potential which determines the commercial success of a new variety.
