Project Number: 6217-21000-006-03
Project Type: Specific C/A

Start Date: Jul 01, 2003
End Date: Jun 30, 2008

Objective:
The objective of this cooperative research project is to conduct greenhouse and field experiments in Syria to identify and characterize resistance to the Syrian strain of Russian wheat aphid (RWA) in wheat and barley developed at the USDA-ARS Plant Science Research Laboratory, Stillwater, Oklahoma that is resistant to the RWA population found in the United States. These wheats and barleys with resistance to multiple sources of virulent RWA will undergo further improvement and be ready to deploy in case a new virulent RWA population, similar to the Syrian population, is introduced to the United States.

Approach:
Since there have been no reports of virulent variants of RWA in the field in the U.S., we will work with collaborators in Syria to test and develop wheat and barley germplasm with resistance to their local populations of RWA. These Syrian RWA populations are known to be virulent to wheats that are resistant to the RWA found in the U.S. We will ship selected RWA-resistant wheat and barley lines developed at Stillwater to Syria for testing against known virulent populations of Syrian RWA. We will also obtain wheat and barley germplasm resistant to the Syrian RWA for testing against the U.S. RWA population.
