Location: Crop Genetics Research
Project Number: 6066-21000-052-003-I
Project Type: Interagency Reimbursable Agreement
Start Date: Dec 1, 2018
End Date: Sep 30, 2019
Objective:
Mitigate damage caused by cotton leaf curl virus to the Pakistani cotton crop, by supporting research that leads to the development of resistant elite lines as well as improved detection and screening methods that will also increase the level of U.S preparedness should cotton leaf curl virus become a problem in the United States.
Approach:
ARS will work with International Center for Agricultural Research in the Dry Areas (ICARDA) to implement this collaborative project. With the goal to develop cotton leaf curl virus (CLCuV) elite cotton lines for Pakistani and U.S. farmers, sources of resistance identified in the first two phases will be incorporated into one elite line to be used to develop cotton varieties with multiple sources of resistance to CLCuV. Putative DNA markers will be tested for their ability to detect CLCuV resistance trait(s) in the absence of visible disease symptoms, which will make marker assisted selection (MAS) possible. The effects of cotton leaf curl virus disease will be mitigated by transferring best management practices to small Pakistani farm families using the farmer field school (FFS) model.
