High linoleic acid soybeans facilitate maximum production of soy-based polyurethane. The objectives of this study were to: 1) Evaluate environmental influence on yield and seed composition traits; 2) Estimate correlation coefficients between linoleic acid with agronomic traits; 3) Validate SSR markers associated with fatty acid QTL in multiple environments and across diverse genotypes; and 4) Evaluate the influence of fertilizers differing in P and K concentrations on seed fatty acids. RG25 was identified as the best genotype to be commercialized for polyurethane production. Strong marker-trait associations across environments included Satt_335, Satt389, Satt556 associated with palmitic and stearic, Satt389 with oleic, Satt389 and Satt537 with linoleic acid. A significant increase in linoleic acid content was observed when plants received modified Hoagland’s solution with 2×K compared to without K. Development of a high linoleic acid soybean line for polyurethane production is feasible using validated SSR markers and high K fertility. / Ontario Ministry of Agriculture, Food and Rural Affairs
