The establishment of the collection began in the early 1970s on the basis of breeding activities. The material includes wild species and landraces, as well as breeders lines and cultivars, both from Germany and

Today the environmental impact of high input agriculture in more favorable environments causes growing concern. By contrast, the impact of breeding in marginal environments has been elusive. The paper discusses evid

Adaptation, variation and selection in marginal areasght of their adaptive significance, specially pointing at their phenotypic expression under stress. Variation in marginal plant populations is discussed on the basis of accumulated knowledge on quantitative traits and isozymes. The common opinion that marginal populations are genetically depauperate

Some consequences of adaptation to extreme environmentsspatial scales of population differentiation are examined predominantly in members of the Poacea. Evidence from environmental situations in which genetically based population differentiation might reasonably be expected to have evolved but has not been recorded are examined. The impact of extreme se

This gene pool is endangered by the increasing practice of grassland renovation. The collection of genetic resources from that marginal habitat serves two purposes, therefore: Utilization of the gene pool in breeding programmes, and conserving the
