Growth and drought stress tolerance in a provenance trial with red oak and selection of plus trees
Selection and characterization of high-quality reproductive material in red oak (Quercus rubra L.) taking intoaccount the drought stress tolerance - TV3: Analysis of the growth of red oak in a provenance test andselection of plus trees
The red oak (Quercus rubra L.), which originates from North America, is the most common foreign deciduous tree species in Germany. Due to its high growth potential and diverse wood utilization, it is one of the potential alternative tree species in times of climate change. The aim of the 'RubraSelect' project is to investigate the growth performance and drought stress tolerance of North American and European provenances in two trial series with three and two trial plots, respectively. These are located in Schleswig-Holstein, East Brandenburg and Hesse. In each case, the planting was done with known single tree seedings.
Background and Objective
RubraSelect will lay the foundation for the production and delivery of high quality reproductive material of
Quercus rubra L. for Germany in the face of climate change. The project aims at the selection and
propagation of trees with superior phenotypes (plus trees) considering their geographic origin as well as
their genetic diversity and adaptive potential. The selection of plus trees will be conducted in planted stands
and in provenance trials based on quality, growth, vitality and genetic marker (Single Nucleotide
Polymorphism, SNP) information. Additionally, plus trees will be characterized at selected biomarkers to
assess their adaptive potential. Progeny trials will be established to test for differences in drought tolerance
among plus tree progenies.
Finally, the genetic basis of growth characteristics and drought stress tolerance will be analysed in a
seedling trial under controlled conditions. Specifically, metabolome and transcriptome and genome
analyses will be used for the development of new drought stress markers responsible for the adaptation to
drought stress conditions. Genome-wide association analyses of genetic variation with trait variation
(drought related traits, metabolites) will be conducted to identify and validate gene markers for growth and
drought stress adaptation.
Approach
The work-packeges of the sub-project of the Thünen Institute of Forest Genetics are
(1) the recording of the phenotypic variation depending on different site conditions (WP7),
(2) the analysis of the reaction of the increase in diameter during and after years of drought (WP9) and
(3) the selection of plus trees and their vegetative propagation as the basis for the establishment of a seed
orchard (WP10) and
(4) reports and presentations of the results in journals and at conferences (WP11)
