Research Project: FIELD TESTING PLUM POX VIRUS RESISTANT GENETICALLY ENGINEERED PLUMS AND THE DEVELOPMENT OF NEW RESISTANT VARIETIES

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

2008 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., in collaboration with members of the NGO Black Sea Biotechnology Association (BSBA), we have developed a draft of a consensus document on the control of PPV in plum through genetic engineering. Plans are also underway for planting and testing the genetically engineered PPV resistant trees in BSBA member states. The ADODR has monitored activities through emails, meetings, and calls.

This research addresses NP 301 (Plant Genetic Resources, Genomics, and Genetics Improvement) Component 3. Genetic Improvement of Crops, Problem Statement 3C: Germplasm Enhancement/Release of Improved Genetic Resources and Varieties.
