Information And Results
Project Deliverables

For objective 1

1. Identify new sources of SCN resistance
2. Release conventional cultivars and germplasm lines with SCN resistant in MG I, II, and III (Cianzio, ISU)
3. Release soybean germplasm lines with SCN and RKN resistance in maturity groups VI. VII and VIII (Arelli, USDA and Zenglu Li, UGA)
4. Improved germplasm lines with SCN resistance from Peking source
5. Improved diagnostic DNA marker assays for selection of SCN (rhg1 and rhg4, and RKN resistance

For objective 2

1. The development of several mapping populations derived from new sources of resistance to SCN, RKN, and RN.
2. Completion of QTL analyses of RKN and RN resistance in the Magellan x PI 567516C population.
3. Completion of QTL analyses of SCN, RKN and RN resistance in the new population derived from the Magellan x PI 567305 population.
4. Completion of the evaluation of over 500 PIs from early MG for SCN resistance.
5. Completion of association mapping study using 50k SNP Infinium Chip data to detect novel genomic regions conveying resistance to SCN.
6. Narrowing down the genomic regions of novel QTL by fine-mapping.
7. The development of molecular markers associated with the genes/QTL identified and test high-throughput SNP genotyping platform using the Fluidigm EP1 system.
8. Robust SNP marker assays for selection of root-knot Ma and Mj resistance

For objective 3

1. Soybean lines with resistance to HG Type 2.5.7 derived from G. tomentella.
2. Soybean lines with resistance to HG Type 1-7 derived from G. tomentella.
3. Mapping populations that can be used to identify the genomic location of SCN resistance genes from G. tomentella.

Final Project Results

Updated June 7, 2019:

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.
