Project Number: 6618-21000-013-48
Project Type: General Cooperative Agreement

Start Date: Jun 06, 2012
End Date: May 30, 2013

Objective:
Develop new rootstock cultivars with higher productivity, better fruit quality, and better tolerance of environmental conditions, pests, and diseases, including hunaglongbing.

Approach:
The project includes four components with interrelated objectives: 1) Develop promising supersour rootstocks through sexual hybridization, screening and selection of progeny, and long term field trials; 2) Improve disease resistance of citrus through manipulation of Poncirus-related defense genes; 3) Produce and test transgenic rootsocks; 4) Evaluate high grafting as a management strategy for HLB (Huanglongbing) disease control.
