1a.Objectives (from AD-416):
Establishing the genetic diversity of virus and vector resistance mechanisms in potato to facilitate the development of durable host resistance. Determining mechanisms of vector transmission of viruses to facilitate the development of effective disease management strategies
1b.Approach (from AD-416):
Potato germplasm is screened for various types and levels of virus and vector resistance using the complete suite of virus strains that infect the crop. The molecular and genetic mechanisms of transmission of potyviruses and luteoviruses by aphids is studied to identify weak links in the transmission process that can be targeted for disruption.
No funds were added to this agreement during FY2012 and research efforts were suspended for the year.
