Genetic variation in blister rust resistance in Scots pine

Project description

The Scots pine blister rust is an emerging threat to the health of future boreal forest, as the changing climate becomes increasingly favorable for fungal pathogens in the north. Using the general level of blister rust resistance in the Scots pine populations and specific resistance among different genotypes, we will assess the genetic basis of resistance and model population responses in Scots pine under various climate and breeding scenarios. Knowledge gained from this research will be valuable for enhancing the efficiency of resistance breeding in Scots pine. The specific aims of this project are:

• Evaluate the genetic variation in resistance to blister rust in Scots pine breeding populations and natural stands and determine the quantitative genetic basis of resistance using long-term progeny trials.
• Study the genomic architecture, particularly structural variation (SV), in relation to resistance variation in Scots pine.
• Develop genomic models for predicting susceptibility in breeding and natural populations of Scots pine.
