| Soybean oil is an environment friendly alternative to fossil fuels as a feedstock in the manufacturing of polyols and polyurethane foam. The objectives of the study were to: 1) Evaluate the agronomic performance of RILs from two soybean populations with altered fatty acid profiles grown across multiple environments; 2) Identify SSR markers associated with fatty acid composition in varying environments and genetic backgrounds; and 3) Identify genotypes that are most suitable for polyol production. Significant genotype, environment, and genotype x environment interactions were observed for all fatty acid traits, with lowest concentrations of polyunsaturated fatty acids obtained in the most southern environment. Strong and stable marker-trait associations across environments included Satt556 associated with stearic acid, Satt534 with linoleic acid and Satt152 with palmitic acid. The RIL E-49 was identified as the best genotype for polyol production for use in the manufacturing of polyurethane foams for the auto parts industry. |
