Research Project: Development of Promising Supersour and Other Rootstocks Resistant to Huanglonging (Hlb)

Location: Subtropical Insects and Horticulture Research

Project Number: 6034-21000-014-14
Project Type: General Cooperative Agreement

Start Date: Oct 01, 2012
End Date: May 30, 2015

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

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 rootstocks; 4) Evaluate high grafting as a management strategy for HLB disease control.
