Collaborative project: Analysis and utilization of grass genetic resources for generating new diversity in fodder and amenity types – Subproject 2
Project
Project code: 2814301207
Contract period: 01.04.2008
- 30.04.2011
Budget: 57,787 Euro
Purpose of research: Experimental development
Genetic resources of the grass genera Dactylis, Lolium und Phleum were examined and utilized for the generation of novel diversity. Interspecific hybrids were generated and existing but non-characterized interspecific bastards evaluated. This resulted in the broadening of the respective gene pools in respect to agronomically important traits. DNA techniques accelerated the breeding program and made it more efficient: SSR markers identified hybrids in Dactylis and Phleum crosses; a newly developed, comprehensive SNP resource permits quantitative genotyping of Phleum populations, while GISH analyses proved the presence of portions of donor genomes in Festulolium introgressions. In summary, the utilization of genetic resources of grasses granted the fulfillment of breeding goals that were beyond reach because of the restricted diversity in breeding material. Thus an expanded crop rotation of grass cultivars with increased biodiversity and an adaptation to climate change are made possible.
