Brief Project Summary:

Genetic resistance to diseases and pests is the most economical, durable and ecologically sustainable approach to control soybean diseases, protect yield and increase yield potential of soybeans. The goal of this research effort is to release superior-yielding germplasm with resistance to diseases, pests and abiotic factors that reduce soybean yields to make them available to farmers. This breeding seeks to improve soybean genetic resistance Phytophthora root rot, brown stem rot, soybean cyst nematode, sudden death syndrome, iron-deficiency chlorosis and emerging stress factors and identify new resistance genes in maturity groups I, II and III.

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

Information And Results
Project Deliverables

1. High-yielding cultivars with defensive traits, released to farmers
2. Germplasm lines possessing defensive traits, released to the soybean breeding community for use
3. New genes for defensive traits (resistance to diseases, pests, and abiotic stress factors)
4. Molecular markers associated with the new genes identified

Final Project Results

IAR2601 SCN Conventional high-yielding cultivar with resistance to SCN derived from a new source of SCN resistance (PI438489B), with resistance to SDS, and low iron deficiency chlorosis scores

AR11SDS Germplasm line resistant to SDS, and to SCN. Registration in process.

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.
