Technical Abstract: The past three years have witnessed rapid accumulation of whole genome sequences and other genomics resources in cucumber. So far, draft genomes of three cucumber inbred lines have been released; many cucumber lines are being re-sequenced using next-generation sequencing technologies; nearly three million ESTs have been were generated; tens of thousands of molecular markers have been developed and several high-density genetic maps have been constructed. These resources are providing new opportunities to expedite traditional plant improvement through molecular marker-assisted breeding in cucumber. However, there is still a large translational gap between utilization of these genomic sequences and field-based breeding. The Cucumber Improvement Program of USDA-ARS/University of Wisconsin at Madison has been dedicated to developing applied genomics tools to fill in this gap. In this presentation I will give a brief overview of ongoing research in our program with emphasis on the following projects: development of a high-resolution, integrated genetic-physical map of cucumber, comparative genetic mapping among Cucumis species to reveal chromosome evolution, and molecular mapping of horticulturally important genes in cucumber.
