Research Project: National USDA Uniform Soybean Tests/Yield, Disease Resistance and Quality Traits Evaluation of Public Breeding Lines (Year 3 of 3)

Location: Crop Genetics Research

Project Number: 6066-21220-016-008-R
Project Type: Reimbursable Cooperative Agreement

Start Date: Oct 1, 2022
End Date: Sep 30, 2023

Coordinate and participate in the Uniform Soybean Tests – Southern States and Northern Region.

The Uniform Soybean Tests is a cooperative testing program that is the main mechanism for U.S. public soybean breeders to obtain multi-state field data to support the release of varieties and germplasm. Separate tests for each of maturity groups OO to VIII are grown in appropriate locations across 18 states and two Canadian provinces. Collaborators screen lines for resistance to important soybean diseases and pests. Seed samples are sent to labs for seed composition analysis. ARS will: a. Organize the Uniform Soybean Test – Southern States and the Uniform Soybean Test – Northern Region including receiving and re-distributing seed to cooperators; maintaining stocks of checks; preparing and distributing location lists, data collection sheets, and entry lists. This will be done by scientists in the Crop Genetics Research Unit in Stoneville, Mississippi and Crop Production and Pest Control Research Unit, West Lafayette, Indiana. b. Collect, validate and compile data for analysis. We will analyze the data and send the results to participants for review and then re-analyze, if required. c. Prepare, copy, bind and distribute the final report. Post final reports online. d. Contribute pedigree data to Parentage Database located at e. Grow tests for maturities IV and V in Mississippi. f. Grow tests for maturities I, II, III and IV in Indiana. g. Screen entries for southern stem canker resistance in Stoneville, Mississippi. h. Screen northern test entries for the Rps gene in West Lafayette, Indiana. i. ARS-NCAUR, Bio-Oils Unit, in Peoria, Illinois, will analyzes seed for protein and oil percentage. j. ARS-Crop Genetics Research Unit, in Jackson, Tennessee, will screen soybean lines for reaction to soybean cyst nematode.
