Association mapping

Association mapping

We are doing association mapping in Salix viminalis. Together with researchers from Rothansted Research we have developed a mapping population with roughly 400 individuals from Central and Northern Europe. The mapping population was planted in a complete randomized block design with six blocks at two sites in England and two in Sweden, during spring 2009. The mapping population has been used to measure growth and phenology traits, drough tolerance and resistance to various pests.



We are taking the approach to look for correlations between phenotypic variation in the mapping population and genotypic variation in candidate genes associated with the traits of interest. Candidate genes are identified from literature and from different QTL studies undertaken by the group. A diverse subset of the population has been used to identify  SNPs in candidate genes by sequencing with Illumina Sequencing Technology.
