Research Project: Rapid Cycling Breeding for the Genetic Improvement of Drying Plums (Prunus Domestica)

Location: Appalachian Fruit Research Laboratory

Project Number: 8080-21000-023-11
Project Type: Specific Cooperative Agreement

Start Date: Sep 30, 2010
End Date: Sep 29, 2015

Objective:
To develop an innovative breeding system to improve the speed and flexibility to deliver unique plum cultivars to meet future challenges of the California plum industry.

Approach:
The 'FasTrack' breeding project proposes to deliver an advanced biotechnology to an existing industry supported plum cultivar development program. 'FasTrack' breeding technology will be developed to specifically meet the needs of the California Dried Plum Industry by integrating the system with the major Dried Plum Industry breeding program and targeting traits highly desired by the industry. The 'FasTrack' breeding system under development at USDA-ARS Appalachian Fruit Research Station is an advanced fruit tree breeding system that uses transgenic early and continually flowering trees to overcome the limitations of juvenility and dormancy, producing the first generation in one year vs. the normal 3-7 years. Unlike conventional breeding, 'FasTrack' crosses will be done in the greenhouse, and only the non-transgenic individuals from segregating populations will be released to the field. Molecular markers will be used to further improve the efficiency of the 'FasTrack' rapid backcross breeding scheme.
