Induction of early flowering in poplar and apple to speed up breeding for resistance to diseases
Breeding of forest and fruit 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.
But to make sure the product range and the quality of forest and trees also in the future, the above mentioned disadvantage in terms of predicted climate change, which will probably faster occur as a genetic adaptation of trees is possible, could have dramatic economic and labour market consequences.
A solution to this dilemma could represent the integration of early flowering genotypes in the breeding process of trees. Such early flowering lines are either available as natural mutants arising from normal flowering representatives or can be produced by the genetic transfer of special flowering-enhancing genes.
