Research Project: DATA COLLECTION TO SUPPORT INTERNATIONAL REGULATORY APPROVALS FOR 'HONEYSWEET' PLUMS

Location: Appalachian Fruit Research Laboratory: Innovative Fruit Production, Improvement and Protection

2010 Annual Report


1a.Objectives (from AD-416)
To develop international collaborative testing programs to evaluate 'HoneySweet' and other Plum pox virus resistant genetically engineered plums in expanded European field tests and to support international exchanges of information between project collaborators.


1b.Approach (from AD-416)
Collaborators in Europe will develop field trials of 'HoneySweet' and additional PPV resistant transgenic plum clones. These field trials will be developed in areas of high PPV infection pressure. Data on tree performance in terms of PPV infection, fruit quality and other agronomic characteristics will be recorded. Pollen flow will be monitored at sites where flowering is authorized. These data will be used to support EU regulators. A meeting of collaborators will be supported as one of the vehicles for the exchange of information on the project.


3.Progress Report

In order to engage European regulators in the evaluation of genetically engineered plums resistant to Plum pox virus (PPV) that have been developed in the U.S., we met with members of the NGO Black Sea Biotechnology Association (BSBA) to develop plans for utilizing the PPV resistant trees and technology, and for meeting regulators and public concerns. A document has been developed that reviews the threat of PPV to stone fruit production and the potential of genetically engineered PPV resistance to significantly reduce this threat. This manuscript is in final preparation for journal submission. Future plans will include testing the genetically engineered plums in the cooperator's fields under the required permits. The ADODR has monitored activities through emails, meetings, and calls.
