Wild cherry (Prunus avium L.) is one of the most important forest fruit species. It is a highly-valued forest tree species which grows in mixed forests of Southern, Central and Western Europe. In forests of Serbia, it belongs to the group of endangered species which has not received enough attention. During the last years, many wild cherry breeding programs have been conducted in Europe with the aim of its preserving and increasing its biodiversity and production of quality wood. These programs begin with the phenotypic tree selection in natural stands and the use of their vegetative parts for the establishment of clonal seed orchards with the main purpose of producing high-quality seed with genetic purity. A similar project was realized in Serbia in the period from 2015 to 2017. This paper presents the activities and the process of the establishment of the clonal seed orchard of wild cherry (Prunus avium L.). A set of 42 trees were selected throughout the whole range of distribution of the wild cherry in Serbia. The selection criteria included the health the status, phenotypic characteristics, quantity and quality of yield. The grafting was performed on the previously planted rootstocks using the scions taken from the selected plus trees. The British method of grafting was applied. The seed orchards were established on two localities, in Požega and Jelova Gora. In both orchards, 42 clones with 20 ramets were set up with the identical spatial layout. The established seed orchards will provide a long term production of sufficient amounts of high-quality seed. At the same time, they will represent ex situ conservation facilities of the available gene-pool of wild cherry in Serbia. Keywords:
