Induction of early flowering in poplar to speed up breeding for resistance to diseases

Breeding of forest trees has internationally, but also in Germany, a long tradition.

Background and Objective

Trees have, however, because of its long use and reproduction periods, the disadvantage that a significant breeding selection for economically important characteristics is very limited. Thus, shortening of the breeding cycle would represent a realistic opportunity to fasten forest tree breeding significantly.
