Pickle Packers International Meeting Proceedings. Technical Abstract: A cucumber project was recently funded by the USDA NIFA-SCRI program which is titled “Translational genomics in cucumber - tool development and application for recessive disease resistances”. This grant was the result of a joint effort of the UW public cucumber research community with strong support and active involvement from the stakeholders. This project has four specific objectives: (1) Empower cucumber translational genomics by developing a SNP array for high throughput genotyping; an integrated, high-resolution genetic-physical map; and virus-induced gene silencing (VIGS) system for functional genomic assays. (2) Apply translational genomics tools to expedite fine mapping and breeding of the recessively inherited resistances against the new downy mildew strain; map-based cloning of the zym gene conferring multiple potyvirus resistances; and understanding of molecular interactions between the downy mildew pathogen and cucumber host; (3) Evaluate economic benefits of genetic improvements of disease resistance on commercial cucumber production; and (4) Conduct an outreach program to enhance communication with all segments of the cucumber industry, and to educate the public on the need for sound scientific practices to resolve biological problems. The long-term goals of this project are to develop molecular breeding tools for more efficient cucumber improvement, especially more effective introgression of recessive disease resistances into elite cucumber lines in order to deliver value-added cucumber cultivars to our stakeholders.
