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-A
Project Type: Cooperative Agreement

Start Date: Oct 1, 2012
End Date: May 30, 2015

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

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.
