Reconciling the goals – grass breeding for an improved grassland husbandry

Johannes Isselstein, Martin Komainda

Grasslands of Europe are extremely divers. They can be grouped into different types and their management and resulting ecosystem services are quite different. To improve the overall performance of grasslands it is required to distinguish between the different grassland types and their potential delivery of ecosystem services. This holds for management measures as well as for forage plant breeding. The present papers analyses the potential contribution of germplasm improvement on the production and environmental function of grasslands and how this potential is determined by the different grassland types. While grassland husbandry is interested in beneficial traits of the grass sward as a whole, plant breeding is always centered around single species. Breeding progress in individual species must be assessed by the performance of the sward and the harvestable herbage. This includes that the performance of new germplasm has to be tested in species mixtures that are common in the farming practice. Apart from forage provision, environmentally important services such as carbon sequestration or biodiversity are becoming more important whereby changes in climate force to explore new candidate species that are not yet part of intensive breeding programs. New species will deliver traits with beneficial effects for grassland farming. Breeding will need to be more focused on bringing together species with complementary traits by selectively combining varieties of different species in a way to capture synergies.
