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

2012 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:

The collaborating organization, the Black Sea Biotechnology Association, is providing logistical support and funding for the U.S. European collaboration in the testing of Plum pox virus resistant plums under field conditions. This work provides important information to U.S. researchers seeking to develop resistant varieties for U.S. growers. Currently, the Black Sea Biotechnology Association is providing support for a field test of 'HoneySweet' Plum pox virus resistant plum that is being undertaken by a collaborator in Romania. This field planting will provide valuable information on the performance of 'HoneySweet' plum under conditions of heavy virus inoculation pressure.
