Research Project: A SECURE SITE FOR TESTING TRANSGENIC AND CONVENTIONAL CITRUS FOR HLB AND PSYLLID RESISTANCE

Location: Subtropical Insects and Horticulture Research

Project Number: 6618-21000-013-27
Project Type: Reimbursable

Start Date: Jul 01, 2010
End Date: Dec 31, 2012

Objective:
Maintain a test site for evaluation of transgenic citrus scion and rootstock genotypes and expression vector strategies for resistance to Huanglongbing and the vector, Asian citrus psyllid.

Approach:
A citrus production site will be maintained at the USDA/ARS Picos Rd. Farm for testing of transgenic citrus resistance to HLB and psyllid. Ongoing strategies to identify resistance to HLB and/or its psyllid vector include many transgenic approaches. All of these research projects ultimately require testing in the field where HLB and psyllid are endemic. The Picos Farm of the U.S. Horticultural Research Laboratory in Ft. Pierce, FL is ideal for this use. It is decided that the best use of this site is to test for HLB/psyllid resistance and control and therefore HLB infected trees are not removed and many citrus blocks are not receiving psyllid control sprays. This site will be available to UF, TAMU and ARS researchers. In addition to transgenic trees, some non-transgenic citrus with reasonable probability of resistance, will be tested.
