This project aims to increase the economic value of future Sitka spruce plantations substantially by using new breeding techniques to select outstanding rare individuals combining high growth rate with good timber qualities. Selection will be made at a very early age based on DNA markers found to be well correlated with later rotation performance.
- Development of ‘Genomic Selection’ in Sitka spruce
- Development of DNA markers
- Early selection for growth rate and timber stiffness based on markers well correlated with later field performance
- Reduction of rotation lengths
- Increasing timber quality
- Massive increase in the economic benefits of growing Sitka spruce in Britain
- Shortening the time between selection in the lab based on the new DNA markers and delivery to the field of improved material.
Results so far
No results at the moment.
The first task is to associate DNA markers with certain tree characteristics measured in the field. Two existing 22-year-old field trials have been identified as perfect for this job; one in Brecon Forest and a sister experiment involving the same parents and families replicated in Kintyre Forest.
Contract started 1st July 2017 and will run until 30 June 2020.
First trees were felled in Brecon, in mid-summer with the co-operation of Natural Resources Wales. The Kintyre site was felled in early autumn. A total of 1,400 trees will be measured in detail with samples returned to Northern Research Station for detailed analysis of growth rate and timber quality in early 2018. Association between DNA markers and phenotypic characteristics will be carried out by Oxford University. Roslin Institute will estimate the breeding value of trees based solely on the DNA markers.
