Soybean seed and oil compositions and methods of making same

A method of obtaining a progeny soybean plant seed comprising the steps of:

• (a) crossing a first soybean plant parent comprising in its genome a first DNA construct comprising a DNA segment expressing a thioesterase with activity on stearoyl acyl ACP with a second soybean plant parent that lacks the DNA construct, wherein the first or second soybean plant further comprises in its genome a second DNA construct comprising a DNA sequence designed to trigger the suppression of an endogenous FAD2 gene, and wherein the first or second soybean plant further comprises in its genome a third DNA construct comprising a DNA sequence designed to trigger the suppression of an endogenous FAD3 gene;
• and,
• (b) harvesting a progeny seed produced on the soybean plant parent bearing a fertilized flower, wherein a progeny plant grown from the harvested progeny seed comprises the first, second and third DNA constructs and produces seed having an oleic acid content of 35% to 57% by weight of total seed fatty acids, a stearic acid content of at least 35% by weight of total seed fatty acids, and a linolenic acid content of 0.68% to 1.14% by weight of total seed fatty acids.
