Brief Project Summary:

This research centers on increasing the yield of soybean by breeding, releasing high-yielding germplasms and cultivars and expanding the genetic diversity of soybeans. The goal is to develop superior cultivars for Iowa farmers. They provide high yield and protection against biotic and abiotic factors to keep farmers competitive and profitable. This is achieved by searching, discovery and introgression of new resistance genes into adapted cultivars to protect the soybeans and their potential yield capacity. Trait focus includes yield, soybean cyst nematode, sudden death syndrome, Phytophthora root rot, brown stem rot, iron deficiency chlorosis and multi-disease and pest resistance. The release of these materials to seed companies and other public institutions contribute to soybean production.

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

Information And Results
Final Project Results

Update:
During 2019-2020, 11 new varieties with high yield and resistance to pathogens of economic importance in Iowa hve been disclosed to ISURF, and if approved by the CALS Germplasm Committee will be produced by the Committee for agricultural Development (CAD) and certified by the Iowa Crop Improvement Association (ICIA) for general public use.

Releases in progress. Before the end of 2020, 45 additional releases will be presented to Iowa State University Research Foundation ( ISURF) and to CALS Germ Committee for further distribution. With this action, all the work accomplished by the ISU soybean project led by Cianzio will be in possession of Iowa State and ISURF, available for future public use.
During the duration of the project
- MTAs 350+
- Total # releases duration of project: 120+
- Expansion of the genetic base of the soybean commodity - new genetic material introduced into production: 20 plant introductions

The project has used plant introduction available for public use, curated by the National Soybean Germplasm Collection USDA-ARS in the following manner:
- 14 accession from the collection have been identified as possible new sources of soybean cyst nematode (SCN) resistance. The accessions have been used in crossing, inheritance research, screening under controlled conditions (greenhouse, growth chambers) and in field plantings to determine resistant phenotypes that later were studied in molecular research. The most promising have made to become public releases.
- 4 accessions have been used in a similar manner for resistance to sudden death syndrome (SDS)
- 1 accession has been used for finding new genes for resistance to Phtytophthora root rot (PRR)
- 1 accession has been used for resistance to Asian Soybean Rust (ASR)
- Educational accomplishments – trained students, Undergraduate: 350 in Iowa and Puerto Rico locations, Graduates: PhD 35, MSc 23
- Published research: Over 200+ research papers in journals of international and national reputation
- Scientific presentations: Over 120 presentations, both nationally and internationally invited

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.
