Wild cherry (Prunus avium L.) breeding program aimed at the use of this tree in the Czech forestry

Abstract

The paper widely introduces European experience in wild cherry breeding because it is the first one from a prepared series of articles aimed at wild cherry breeding in the Czech Republic. Beginnings of wild cherry breeding program for the Czech forestry are described. Plus trees were certified, seed orchards, clone archives, progeny and clonal tests were established. Clones were tested for fl owering of grafts in reproductive plantations. Progenies and clones were tested for growth parameters in progeny and clonal tests. Progenies and clones in every breeding plantation were tested for damage by aphids.
