A new test approach to identify the origin of forest reproductive material in Europe
An important proportion of the forests in Germany have been generated by using non- autochthonous reproductive material. These stands can be unstable or well adapted depending on the origin of the seed material. The information on the origin of the material is particularly important for selected seed stands because these stands generate the material of future plantations.
In frame of the project we want to develop genetic reference data on the original spatial genetic structure in Europe of the four main tree species Norway spruce (Picea abies), beech (Fagus sylvatica), pedunculate oak (Quercus robur) and sessile oak (Quercus petraea). With comparative genetic inventories we want to compare the genetic composition of samples from selected seed stands with the locally expected genetic structure in the above mentioned genetic reference data. So we want to detect stands under risk with limited adaptation to the climate and stands that are genetically well adapted. The results of the project will be used to generate recommendations for the selection of seed stand and their future use. For each tree species we will apply next generation DNA sequencing techniques in order to detect a few thousand variable gene regions (SNPs, Indels). From these potential gene-markers we will select 180 markers for genetic inventories on 1000 autochthonous trees from 100 stand. So we generate the genetic reference data and compare this with the genetic composition of 1000 plants from 100 selected seed stands.
The results of the project are relevant for the practical forestry (forest owners, forest administration, nurseries).
