Information And Results
Project Deliverables

Commercial varieties and public germplasm will be identified with resistance to frogeye leaf spot. Variety results will allow producers, seed companies, consultants, etc. to select resistant varieties. If producers have access to resistant varieties, this will presumably reduce the need for applying fungicides. It will also provide a needed resource to producers with fungicide resistant isolates.
Public lines that are identified with resistance will assist plant breeders with developing new varieties. Potentially new resistance genes from Plant introductions will position breeding programs to have these genes in germplasm, should races develop that can defeat Rcs3.

Final Project Results

Progress has been made to develop novel sources of resistance to Frogeye Leaf Spot. For the first time, resistance sources to Cercospora Leaf Blight have been initially identifed. New means to screen for these two major diseases are under development to enhance the breeding for resistance. Methods to detect fungicide resistance of Frogeye strains to foliar fungicides has been determined, that in turn, has led to establishment of a geographic map for incidence of fungicide resistance. Foliar fungicides are screened annually for efficacy against all major foliar diseases and published widely. A prediction system for Septoria brown spot has initially been developed.

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.
