Brief Project Summary:

The objective of this soybean breeding project is to develop high-yielding SDS-resistant soybean cultivars for farmers and germplasm lines for the seed industry. Varieties and lines are being developed for maturity groups I to VI.

The program has successfully released several new soybean varieties and germplasm lines with SDS resistance: the cultivar Saluki 4313 (MG V), two germplasm lines AR10SDS (partially resistant to SDS), and AR11SDS (resistant to SDS). Both germplasm lines are also resistant to soybean cyst nematode. Another germplasm line, EO7051, is highly resistant to SDS. Several new plant introductions in the USDA soybean germplasm collection have been identified as SDS-resistant....

Final Project Results

The program has successfully released several new soybean varieties and germplasm lines with SDS resistance. Dr. Kantartzi has released cultivar ‘Saluki 4313’ of MG V; Dr. Cianzio has released two germplasm lines AR10SDS (partially resistant to SDS), and AR11SDS is resistant to SDS (both germplasm lines are also resistant to soybean cyst nematodes); and Dr. Wang has released a germplasm line identified as EO7051, which is highly resistant to SDS.

Dr. Hartman has identified new plant introductions in the USDA’s soybean germplasm collection which are resistance to SDS. Dr. Bond has conducted the SDS Soybean Variety Regional Test that evaluates over 200 advanced breeding lines from the public sector. These programs are generating new genetic resources for soybean breeders working on developing new soybean lines with improved resistance to SDS.

The soybean breeders associated with this project (B. Diers, D. Wang, J. Orf, P. Chen, S. Kantartzi and S.R. Cianzio) are involved in soybean breeding efforts to improve genetic resistance to SDS. They are making crosses to develop new SDS-resistant germplasm populations, advancing experimental lines, conducting field evaluations in each state on replicated field tests, and evaluating advanced experimental lines in regional tests. The germplasm populations are also being used to develop molecular markers which can be used in soybean breeding programs to predict SDS resistance.

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.
