A FORAGE GRASS AND LEGUME PLANT COLLECTING EXPEDITION IN CZECHOSLOVAKIA 1992

The Plant Genetic Resources Unit (PGRU) of the Institute of Grassland and Environmental Research, Welsh Plant Breeding Station (IGER, WPBS), UK, and the Grassland Research Station, Zubri(GRS, Z), in 1992 part o f OSEVA Research Institute for Fodder Crops, Troubsko (OSEVA, RIFC), C zechoslovakia, carried out a collaborative plant collecting expedition in Czechoslovakia between 10 August and 29 August 1992. 14 geographic al sub-regions of Czechoslovakia were covered with centres of collecti on in Bohemia, Moravia and Slovakia. The expedition concentrated on a range of vegetation from managed semi-natural grassland to wild, un-ma naged grassland. The IGER team collected mainly vegetative samples and the GRS, Z team collected seed samples of forage grass and legume pop ulations. Detailed collection site data was recorded at every site. Sa mples were collected from 67 sites. Vegetative collections of Lolium s pp. (34 populations) and Trifolium spp. (39 populations) and seed coll ections of other species (57 populations) were made by the IGER team. Seed collections of Lolium spp. (26 populations), Trifolium spp. (19 p opulations) and other species (28 populations) were made by the GRS, Z team (Table 2). A diverse range of habitats was sampled covering a ra nge of altitude, management systems and ecological conditions. Wild gr assland was easily found but semi-natural grassland was uncommon in th e collective farming landscape. Entry into a free-market economy is fo rcing changes on the collective fanning system which dominates Czechos lovakian agriculture. Changes in crops and management practices will l ead to a further reduction in the area of semi-natural grassland and g enetic erosion of the unique forage grass and legume populations in Cz echoslovakia. The collecting expedition took place in August 1992, 5 m onths before Czechoslovakia was divided into the separate states of th e Czech Republic and Slovakia. In the text 'Czechoslovakia' is used to reflect the situation at the time of the collecting expedition.
