Sta tus of National Grass Collection and its utilization INTRODUCTION Bo tan ica l Gard en of PBAI i n B yd goszcz h as b een active since 1951. Plant collections are connected with scientific activity, co-co-ordinatedordinated by The National Centre for Plant Genetic Resources of PBAI in Radzików. The main important collection (()g(ypsince 1971) is grass collection (ecotypes of pasture and turf grass species, ornamental and wild growing, native and foreign). There are also collections: plants for reclamation of waste areas and abandoned lands, usable pl ant s ––memedici nal , aromati c, d ecorati ve, (including glasshouse species). Since 1.01.2007 Botanical Garden has been a part of National Centre for Plant Genetic Resources in Radzików „National grass collection” in Botanical Garden in Bydgoszcz Established in 1971 as „edtiducation collection” for recognize grass species occurrenced during collecting missions. Systematically enlargement for species from different regions, at present accounts ~~650650 taxons.

The above collection consists: woody plants of short field rotation (willow Salix spppp., poplar Populus spp).), perennial dicotyledonous plants (Helianthus tuberosus, Sida hermappphrodita, Silphium perfoliatum, Reynoutria japonica), perennial CC--44 ggp(rass species (Androppgogon gerardi, Panicum virgatum, Miscanthus sp., Spartina pectinata).

There are 14.818 grass accessiithbkThions in the genebank now. The grass collection consists of more than 140 species. Grasses databases requires MOS analysis. There are decided to select accssions for Core Collection, too. Thank you for your attention.
