Soybean [ Glycine max (L.) Merr.] oil with elevated palmitate content may be useful for producing plastic fats without hydrogenation. The mutant line A27, with ≈160 g kg −1 palmitate, was developed by treatment of seeds of ‘Kenwood’ with ethyl methanesulfonate. The objective of this study was to determine the genetic control of elevated palmitate content in A27. A27 was crossed to Kenwood and to lines possessing the fap1 , fap2‐b , fap3 , fap4 , or fap6 alleles for altered palmitate. Analysis of the F 1 , F 2 , and F 3 generations indicated that A27 had an allele for elevated palmitate at a single locus, designated fap5 , that exhibited additive gene action with Fap5 and mutant alleles for altered palmitate content. The fap5 locus was independent of the fap1 , fap3 , fap4 , and fap6 loci, but closely linked to the fap2‐b locus.
