Research Project: 3% LINOLENIC ACID PUBLIC SOYBEAN GERMPLASM IN THREE MATURITY GROUPS

Location: Plant Genetics Research

Project Number: 5070-21000-032-01
Project Type: Reimbursable

Start Date: Apr 01, 2008
End Date: Mar 31, 2011

Objective:
Develop public soybean germplasm containing less than 3% linolenic acid in the oil fraction in three unique platforms for a range of maturity groups.

Approach:
1. Make nine crosses and develop initial populations segregating for GmFAD3A and GmFAD3C alleles. 2. Use molecular markers to select desired genotypes. 3. Backcross selected genotypes and develop segregating populations. 4. Use molecular markers to select desired genotypes in 75% recurrent parent genome. 5. Advance material identified with desired genotypes. 6. Evaluate fatty acid profile of selected lines.
