Research Project: Metabolomic Profiling to Accelerate Development of Huanglongbing (HLB) Tolerant Rootstocks

Location: Subtropical Insects and Horticulture Research

Project Number: 6034-21000-018-12-R
Project Type: Reimbursable Cooperative Agreement

Start Date: Jul 1, 2015
End Date: Jun 30, 2018

Objective:
Accelerate the development of new citrus rootstocks with high productivity, good fruit quality, and tolerance to huanglongbing disease and other disease.

Approach:
Mass spectrometry-based metabolomics analyses will be performed on rootstock and scion portions of field- and greenhouse grown citrus trees. Metabolite profiles will be correlated with cultivar performance and disease resistance. New candidate rootstocks will be selected based on metabolite profiles. Selections will be planted into replicated field trials, and the best new rootstocks will be released for commercial use.
