Breeding strategies for forest trees: concepts and challenges

T White

Abstract


This paper describes some recent developments that affect the way forest geneticists think about breeding strategies for forest trees. The topics are grouped into several categories: (1) General Concepts ; (2) Breeding Population Size ; (3) Breeding Population Structure ; (4) Management of the Breeding Population ; and (5) Incorporating New Technologies in Tree Improvement Programs. The last major section on new technologies highlights: (1) The increasing importance of hybrid breeding in tree improvement programs: (2) The potential of somatic embryogenesis as a biotechnology leading to clonal forestry for some commercially-important species ; and (3) The need for forest tree breeders and molecular geneticists to work together to incorporate promising new technologies into applied breeding programs.
