Research Project: Genomics-Aided Development of Introgression Lines of Cucumis Hystrix for Cucumber Improvement -CFDA #10.310

Location: Vegetable Crops Research

Project Number: 5090-21000-062-37-A
Project Type: General Cooperative Agreement

Start Date: Nov 1, 2013
End Date: Jul 31, 2017

Objective:
1. Develop C. hystrix introgression lines aiming to transfer of downy mildew and root knot nematode resistance into cultivated cucumber. 2. Understand the mechanisms of homologous recombination between cucumber and C. hystrix chromosomes.

Approach:
1. Develop C. hystrix introgression lines. 2. Conduct whole genome sequencing and draft genome assembly for C. hystrix. 3. Develop linkage map and establishment of syntenic relationships between C. hystrix and cucumber chromosomes. 4. Develop introgression lines with backcrossing and marker-assisted selection of C. hystrix chromatins. 5. Screening tests for downy mildew and root knot nematode resistances.
