Research Project: Determine the Effect of Soybean Vein Necrosis Virus (SVNV) on Yield

Location: Soybean/maize Germplasm, Pathology, and Genetics Research

Project Number: 5012-22000-022-06-R
Project Type: Reimbursable Cooperative Agreement

Start Date: Oct 1, 2016
End Date: Sep 30, 2019

Objective:
To determine the effect of soybean vein necrosis virus (SVNV) on yield.

Approach:
During the 2015-16 fall/winter, we were successful in establishing methods to rear viruliferous soybean thrips and now have colonies of thrips with and without SVNV. These will be used to infest/inoculate plants the from 2016 summer plots. As in 2015, we will use both large plots and caged plants for experiments. Since we have been successful at rearing the thrips and keeping virus concentrations high, large colonies of thrips will be used to infest soybean plants to evaluate soybean cultivar resistance and potential yield loss. We will continue with these field plot trials in FY17 and include more research on evaluating soybean germplasm for resistance to thrips and SVNV.
