Project Summary

Fusarium solani root rot is one of the most significant root rot problems in Minnesota. This is the second year of a study intended to develop a screening technique to identify cultivars that could be used as parent material in a breeding program to introduce Fusarium solani root rot resistance into marketable soybean varieties. This will be done by identifying soybean cultivars that exhibit resistance or partial resistance to colonization by Fusarium solani under optimal infection conditions. Then determine if SCN infection increases the severity of root rot and determine the minimum SCN population that is required to increase the severity. Finally, they will verify if the partial resistance identified remains effective at elevated SCN population levels. This is important in Minnesota because of the severity of both Fusarium root rot and SCN infestations and their ability to reduce soybean yields.

Project Objectives

1. Develop a screening technique to identify cultivars that could be used as parent material in a breeding program to introduce Fusarium solani root rot resistance into marketable soybean varieties.
2. Determine if SCN infection increases the severity of root rot and determine the minimum SCN population that is required to increase the severity.
3. Verify if the partial resistance identified remains effective at elevated SCN population levels.
