Patent ID: 7790953

Claim:
A method of obtaining a soybean plant with an altered seed oil fatty acid composition comprising the steps of: a) crossing a first soybean parent line having a seed oil fatty acid composition comprising a linolenic acid content of about 3% or less of total seed fatty acids by weight with a second soybean parent line having a seed oil fatty acid composition wherein the i) level of oleic acid is greater than about 55% of total seed fatty acids by weight, or ii) wherein both the level of saturated fatty acid is about 8% or less of total seed fatty acids by weight and the level of oleic acid is greater than about 55% of total seed fatty acids by weight, said second soybean parent line comprising either a transgene that decreases the expression of an endogenous soybean FAD2-1 gene to provide the level of oleic acid greater than about 55% of total seed fatty acids by weight of said second parent soybean line of (i); or both a transgene that decreases the expression of an endogenous soybean FATB gene and a trans gene that decreases the expression of an endogenous soybean FAD2-1 gene to provide the level of saturated fatty acid of about 8% or less by weight and the level of oleic acid greater than about 55% of total seed fatty acids by weight of said second parent soybean line of (ii); and b) obtaining a progeny plant exhibiting a seed oil fatty acid composition comprising a linolenic acid content of about 3% or less of total fatty acids by weight and also comprising either i) an oleic acid level in the range of about 55% to about 80% of total seed fatty acids by weight, or ii) both a saturated fatty acid level of about 8% or less of total seed fatty acids by weight and an oleic acid level of about 55% to about 80% of total seed fatty acids by weight, thereby obtaining a soybean plant with an altered seed oil fatty acid composition.
