Research Project: An Integrated Approach to the Accelerated Development of Rootstocks that Impart Huanglongbing Tolerance to Trees Grafted with Commercial Scions

Location: Subtropical Insects and Horticulture Research

Project Number: 6034-21000-018-08-R
Project Type: Reimbursable Cooperative Agreement

Start Date: Mar 15, 2017
End Date: Mar 14, 2022

Objective:
Develop new citrus rootstocks with improved tolerance to huanglongbing.

Approach:
Conventional citrus breeding and testing: 1) Create and select hybrids with best potential for huanglongbing tolerance. 2) Conduct screening of rootstocks for huanglongbing tolerance. 3) Identify differences between huanglongbing tolerant and susceptible rootstocks to reveal mechanisms and selectable markers. 4) Establish field trials with selected rootstock hybrids and collect field performance data. 5) Release huanglongbing tolerant rootstocks for commercial use.
