1Jake is a soybean line with normal oleic acid content and wild-type FAD2-1A; M23 and 17D are soybean lines with mutant FAD2-1AΔ and FAD2-1A S117N alleles, respectively. PI 283327 and PI 567189A are soybean lines with mutant FAD2-1B P137R and FAD2-1B I143T alleles, respectively. S08-14788 is a soybean line selected from population 2 that inherited the mutant FAD2-1B P137R alleles from PI 283327. 2AA = wild-type FAD2-1A alleles, aa = mutant FAD2-1A alleles derived from M23 or 17D, BB = wild-type FAD2-1B alleles, bb = mutant FAD2-1B alleles derived from PI 283327 or PI 567189A.
