Preservation and characterisation of old Czech sweet and sour cherry cultivars
A considerable amount of sweet and sour cherry cultivars had been cultivated until the beginning of the 20th century in the Czech Republic. Sweet and sour cherry cultivars, grown historically on the territory of the Czech Republic, represent objects of cultural identity and an integral part of cultural landscape. Because of the possible extinction of indigenous sweet and sour cherry genotypes, due to changes in property ownership (nationalization, collectivisation) and in priorities of agricultural production (intensification), the program for collecting, long term conservation and characterisation of older cultivars and landraces was started. This paper describes conservation that employs both in situ and ex situ techniques in a complementary manner. Regions and environments not affected by the commercial farming and recreation expansion, as are national parks, protected landscape areas, former army areas in border mountain ranges, were selected for in situ search. Important cherry accessions were localized by Global Positioning System (GPS) and in situ registered. Grafts were taken from important genotypes and these accessions were transferred to germplasm collections of Research and Breeding Institute of Pomology (RBIP), Holovousy Ltd. The genetic diversity of Czech sweet and sour cherry genetic resources has been investigated using phenotypical characterization. This phenotypical characterization revealed high diversity of analysed germplasm. Genotypes varied in tree size, productivity, ripening time, fruit size, fruit quality and disease resistance. The most important sweet and sour cherry landraces are described in the presented paper.
