The Rosaceae Family is represented by approximately 3,000 species of diverse plants, primarily confined to temperate climates. The family has a rich variety of architectural forms and contains herbaceous, tree and shrub species. Many family members are readily recognizable because of their edible seasonal fruits that are prized for their unique flavors, colors and nutritious properties (e.g. apple, strawberry, raspberry, pear, cherry, plum, apricot, pear), as well as familiar ornamentals (e.g. roses) and nuts (e.g. almonds). This book covers progress in recent genomic research among the Rosaceae, grounding this firmly in the historical context of genetic studies and in the application of genomics technologies for crop development. A general introduction precedes summaries of genomics research and applications on a crop by crop basis, each authored by a panel of active researchers in each particular crop. This volume is a considerable value as a resource for workers in the Rosaceae operating at all levels, from research scientists in genetics, genomics and breeding, to graduate and undergraduate students.
