These pages review the work performed by the Forestry Commission and Forest Research on tree improvement following the 50th aniversary of its establishment which passed in 1998.The genetic background describes the scientific procedures of tree breeding and the technical terms used in the remaining pages.All species are referred to by their common name in English.
