The aim of this research was to gain more insight into the genome of the garden strawberry (Fragaria x ananassa), economically the most important soft-fruit world-wide. The genome of strawberries is quite complex, as it contains eight copies of each chromosome (octoploid), whereas humans and most other organisms only contain two (diploid). We developed new analysis methods for DNA based molecular markers, and then applied these methods in the creation of a genetic map for strawberry. This genetic map covered all the chromosomes of strawberry and gave us interesting insights into its genomic composition. Finally we applied these tools for finding the genetic location of resistance against crown rot disease (Phytophthora cactorum) and the genetic location of the ever bearing trait (fruiting all summer).
The information generated by this thesis has helped both academic strawberry researchers as well as strawberry breeders in the application of molecular markers in strawberry.
