Brief Project Summary:

Recently, a field-assessment method based on a colony-forming unit and stem and root severity was developed, and this method has remained the only alternative option for screening and identifying resistance against charcoal rot. This project aims to evaluate different inoculation techniques in controlled environment that can differentiate resistance lines from susceptible ones, to compare and validate the reactions of cultivars obtained through this technique with that of field evaluation technique and evaluate variations among Macrophomina phaseolina isolates for aggressiveness using a greenhouse technique.

Key Benefactors:
farmers, agronomists, extension agents, soybean breeders, seed companies

Final Project Results

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.
