How can the wealth of genetics and genomics data generated for the major Rosaceous crops be utilised to enable the development of superior varieties of economically important species such as apple, raspberry and strawberry? The applied Rosaceous genomics group is focussed on the development of molecular tools for the breeding and selection of apple, strawberry and raspberry varieties. We are involved in the development of molecular markers, genetic linkage maps, and the identification of genes responsible for major traits including fruit quality and disease resistance. The group then works with the breeders to enable the deployment of marker technology into the breeding pipeline. In addition to our molecular research, we maintain a core germplasm collection of raspberry, strawberry, blackberry, currant and blueberry genotypes, and have two programmes for the genetic improvement of raspberry and blueberry.
