Project Summary

The USB goal of achieving 18 million acres of high oleic soybean planted by 2023 is achieved by continuing to support development of diverse sources of high oleic soybean germplasm. The US soybean producer needs high yielding high oleic/low linolenic soybean varieties to provide the market with high value, highly functional soybean oil with zero trans fats. This project will conduct soybean germplasm development and research that result in licensing to private seed companies that release high oleic/low linolenic varieties targeted to all US maturity groups (00-VIII).

Project Objectives

Objective 1: Develop and release competitive yielding non-GMO and herbicide resistant soybean germplasm lines containing the high oleic/low linolenic (HOLL) acid trait in all US maturity groups.

Objective 2: Determine the optimum allele combinations to produce environmentally stable high oleic/low linolenic acid soybean germplasm lines for US soybean production environments.

Objective 3: Determine yield potential and seed composition interactions of the high oleic acid trait along with other oil and meal traits.

Project Deliverables

• Non-GMO and herbicide resistant soybean germplasm lines with >75% oleic acid/<3% linolenic acid and competitive yields in MG 00-VIII.
• Strategy for backcrossing and forward crossing four genes to achieve target fatty acid profiles in different production environments. Extension recommendations for producers using HOLL soybean varieties.
• Research report on the status of the high oleic trait interactions with other oil and meal traits. Soybean germplasm with HOLL trait plus low saturated fatty acids. Soybean germplasm with HOLL trait plus enhanced nutritional energy meal/ENEM trait.

Progress of Work

Updated June 14, 2019:
Finances: This is year 3 of a 3 year project. I believe the university sub-agreements are all scheduled to terminate August 30, 2019, making the month of September a funding issue. We have submitted a proposal for FY2020 funding for this project.

We continue to conduct soybean breeding research to develop and deploy an optimized breeding pipeline to develop high oleic/low linolenic acid (HOLL) soybean varieties. During this reporting period most activities involved setting up 2019 field experiments and planting. Some locations had challenging weather that delayed planting or led to planting in sub-optimum environmental conditions.

Besides state and program level yield testing, this project is evaluating 58 HOLL lines in the 2019 Uniform Trials program. The maturities for these lines range from MG 0 to MG VI.

The backcrossing program continues to deliver germplasm back to the breeding programs to finalize the selection of HOLL versions of the nominated elite lines from each of the breeding programs.

My program shared HOLL seed for crossing and evaluation with all of the breeders. This was updated HOLL germplasm in a diversity genetic background (MG III or MG IV) and MG III HOLL germplasm with an enhanced yield trait. We also provided limited seed of HOLL lines targeted to each MG in the program (with the exceptions of MG 0, I and later than MG V which should be available next year). We provided semi-determinate HOLL MG V line to Tennessee. We also provided HOLL germplasm plus the low RFO trait to project participants.

While this project does not get involved directly in commercialization or forecasting, interest is high for high oleic soybeans and commercial seed increases are being planted.

Final Project Results

Benefit to Soybean Farmers

• Provides greater choice, availability, and seed costs for high oleic varieties.
• Premiums for high oleic.

Performance Metrics

High yielding high oleic + low linolenic germplasm lines will be developed and available for release to producers – either directly from the university foundation seed outlets or licensed to private seed companies. Specific KPIs are listed below by objective:

• The outcomes of this project are high oleic/low linolenic acid soybean germplasm lines with the first releases, up to 8 germplasm lines, beginning in 2019, with up to 157 backcrossed high oleic/low linolenic acid soybean lines available in the pipeline through 2021 for yield test and release. Germplasm lines developed by the 8 breeders and geneticists represent all Maturity Group geographies in the U.S. and can benefit producers in all soybean growing states. Utilization of HOLL varieties by producers will contribute to the strategic goal of USB to grow high oleic varieties on 18 million soybean acres by 2023, and thereby recapture lost market share in the oilseed market.
• The target audiences of seed companies, processors, oil end users, and farmers will benefit from a stable and reliable source of high oleic/low linolenic acid soybeans across US production environments and will begin to adopt varieties, or advance material toward commercialization.
