Accelerate breeding for tree resilience and wood quality in spruce in view of global changes

 

Funding period: 2020-2024
Lead: Patrick Lenz
Total GRDI funding: $612,750

The main objectives of the project relate to: i) the identification of climatic constraints that influence growth in conifers such as spruces; ii) the identification of new traits and new phenotypes to assess tree resilience and characterize spruce breeding populations; iii) the development of genomic breeding tools for resistance/recovery to abiotic stress (drought, frost).
