Project Number: 6402-21310-003-13
Project Type: Specific Cooperative Agreement

Start Date: Sep 29, 2010
End Date: Sep 29, 2013

Objective:
Collaborate with ARS researchers to provide germplasm for Cotton Leaf Curl Virus (CLCuV) screening and transfer resistance identified into adapted cotton lines. Cooperative work with DREC will ensure timely production and transfer of seeds for Cotton Leaf Curl Virus (CLCuV) screening in Pakistan. Lines identified with resistance can be crossed to adapted cotton lines and the progeny evaluated quickly and efficiently. Resistant and susceptible lines of the same species can be crossed to develop mapping populations.

Approach:
DREC will increase some of the germplasm accessions from the Cotton Germplasm Collection, and process seed for Cotton Leaf Curl Virus (CLCuV) screening. Putative resistant lines will be used as parents in crosses to transfer resistance to cotton lines adapted to U.S. cotton growing regions. Markers for resistance will be tracked in progeny of crosses involving parents resistant to CLCuV to confirm transfer of the resistance genes, and progeny will be evaluated under field and greenhouse conditions for suitable agronomic properties and fiber quality.
