Brief Project Summary:

This research aims to determine the occurrence and distribution of viruses infecting soybean in the Delmarva region. A major goal is to provide an update on the current status of soybean viruses in the Delmarva region and partial characterization of some of the virus isolates. To determine the level of virus infection, work involves conducting a survey of soybean fields for two consecutive years. Material gathered from the surveys is used to isolate and characterize viruses. This research also evaluates soybean germplasm against virus isolates from Delmarva.

Update:
Soybean is affected by a wide range of diseases caused by fungal, bacterial, and viral diseases as well as plant-parasitic nematodes, resulting in reduced quality, yield, and profitability in recent years. This project targets soybean virus diseases as a problem faced by soybean production in the Delmarva region. In 2019-2022, a total of 184 soybean samples displaying viral disease symptoms, including mosaic, mottling, chlorosis, stunting, yellowing, and vein necrosis were collected from different fields in geographical regions of Maryland, Delaware, and Virginia. The virus survey was carried out using the enzyme-linked immunosorbent assay (ELISA) serological assay. The most common viruses of soybean with high infection rates include the Soybean mosaic virus (SMV, 19.35%), Soybean vein necrosis virus (SVNV, 10.85%), Alfalfa mosaic virus (AMV, 1.61%), Bean yellow mosaic virus (BYMV), and Bean pod mottle virus (BPMV). In addition, we studied the virus seed transmissibility of soybean under greenhouse and field conditions. We will verify the virus infection previously detected by ELISA by the highly sensitive RT-PCR method.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
