Project Type: Cooperative Agreement
Start Date: Oct 1, 2024
End Date: Aug 31, 2025
Objective:
Our goal is to increase soybean value for the entire value chain by selection of soybean with consistent higher levels of protein and excellent yield that will aid in the development of commercial soybean lines with an improved nutritional bundle. To achieve this goal public soybean breeders need multi-location multi-year data to support the release of lines. Private seed company breeders need data to select public lines to be licensed for sale to farmers and/or used in their breeding programs. The Uniform Soybean Tests provide objective data on yield, agronomics, seed composition (protein, oil, fatty acids and oligosaccharides [sugars]), pest reaction and disease reaction to facilitate these decisions. This will provide high yield, higher protein soybean varieties for U.S. soybean farmers that directly increases their profitability. The specific objective of this project is to perform carbohydrate (sugar) analysis of seed of selected lines and cultivars submitted to the Uniform Soybean Tests - Northern Region and Uniform Soybean Tests, Southern States.
Approach:
The Cooperator will analyze seed of selected experimental lines and selected checks produced in the Uniform Soybean Tests for carbohydrates in seed. Carbohydrates (sugars) will be extracted and analyzed by High Performance Liquid Chromatography for Northern Region and Uniform Soybean Tests, Southern States (250-450 samples). Percent sucrose, raffinose and stachyose content in the seed will be sent to the Agency for further analysis and inclusion in the annual report for the Uniform Test program. The data and results will be shared with program participants to inform decisions about which line(s) to include in further testing and development efforts in their respective breeding programs.
