Genetic and morphological diversity in the Icelandic woodland strawberry (Fragaria vesca L.)

The strawberry is one of twenty most valuable crop plants in the world, it is economically viable and a desired commodity of most. The strawberry genus (Fragaria) contains considerably few species but only on grows in Iceland, the F. vesca. The plant is the most widespread of all strawberry species recently gone through whole genome sequencing. The aim of this research was to assess the morphology of the Icelandic strawberry population by collecting plants that could represent the whole population, make them acclimate in a controlled environment and measure their descriptive characteristics along with other types and cultivar for comparison. The second aim was to sequence genome barcodes from chloroplast DNA and nuclear DNA. The results were used to construct a phylogenetic tree using the Neighbor-Joining method. The results indicate some level of biodiversity within the Icelandic population both morphologically and genetically. The morphology assessment separates the Icelandic populations in two subpopulations and the genetic results to not reject that conclusion. Phylogenetic analyses of the nuclear genome barcode cluster the samples with European individuals of F. vesca but not the American population. Contradicting, the chloroplast genome barcode indicates that a maternal relationship with the American subspecies bracteata.
