Research Project: Characterization of Potato Leafroll Virus Resistance Derived From Solanum Etuberosum.

Location: Small Grains and Potato Germplasm Research

Project Number: 2050-21000-032-08-R
Project Type: Reimbursable Cooperative Agreement

Start Date: May 1, 2012
End Date: Apr 30, 2015

The goal of this proposal is to characterize Rlretb, a gene for resistance to potato leafroll virus (PLRV) from the potato species Solanum etuberosum, and identify molecular markers tightly linked to Rlretb that would be useful for marker-assisted selection and for the eventual cloning of the gene.

The ARS potato breeding and pathology program at Aberdeen, Idaho will conduct field screening for resistance to PLRV and greenhouse grafting studies evaluations that will elucidate the mechanisms of resistance to potato leafroll virus conferred by Rlretb. Research responsibilities also will include hybridization to synthesize diploid populations segregating for Rlretb, which would be useful for the fine mapping of this gene.
