Because of the possible extinction of indigenous landraces in the territory of the Czech Republic, the program for collection and long term conservation of fruit landraces was initiated. This paper describes conservation that uses both in situ and ex situ techniques in a complementary manner. Important landraces found within 12 regions of the Czech Republic were registered, evaluated and the in situ site was localized by global positioning system (GPS). The following accessions were marked for in situ conservation: apple (409), sweet cherry (266), pear (91), plum (42), sour cherry (27) and berry fruit (18). Specific accessions (cultivars) for on-farm conserva-tion in a given region were selected according to the incidence and representation of genotypes in particular areas. Nursery stock production for on-farm plantations is described. Because of the need for longevity, seedling rootstocks were used for propa-gation of planting material for on-farm plantations. Four on farm plantations (KRNAP Vrchlabi, “Orchard of Reconciliation” Neratov, National park Podyji - Znojmo, National park Sumava) were successfully established in a traditional form of large orchard trees on seedling rootstocks. Four established on-farm plantations ensured the long term preservation of landraces in original areas.
