Twenty five years of systematic collecting activities on plant genetic resources in the Czech Republic

Popis výsledku v původním jazyce

Gathering, evaluation and research of plant genetic resources has a long tradition in the Czech Republic. Since fifties, crop varieties of both the Czech and World assortments had been gathered, evaluated, used in research and breeding, and conserved in the Czech Gene Bank. The first collecting expeditions for landraces were organised significantly later, in the seventies and eighties. The Gene Bank understood and highlighted the importance crop wild relatives (CWR) in 1989 and proposed a programme for increasing of their share within collections. The first collecting of CWR started in 1990 and regular annual collecting in 1993. Altogether 27 collecting expeditions have been organised and 4 618 seed samples have been collected in the territory of the Czech Republic. A great attention has been devoted to native CWR, which successfully fulfilled the gap in the Czech Gene Bank. The Czech Republic is very diverse in ecological conditions and habitat types, thus the amount of CWR on its territory is very high. Prevailing collected samples are fodder legumes, grasses, medicinal, aromatic and endangered plants. Unfortunately, germplasm erosion was very intensive in the case of landraces and old cultivars. Landraces of seed propagated species are very rare in the Czech territory, more common are among the fruit trees. Both landraces and CWR are important for breeding, for increasing the diversity of agricultural landscape, as feed sources for pollinators or in case of legumes as fixators of atmospheric nitrogen. Retrospective analyses of collecting expeditions and gathered accessions are outlined and discussed in the article.
