The researchers aimed to create soybean seeds with stable high oleic acid and low linolenic acid content, along with other desired fatty acid modifications. They combined different alleles to achieve this in multiple field environments over 2 years. They successfully reached the target of high oleic acid with low linolenic acid using a 4-allele combination. However, they did not achieve the desired stearic acid content. By using specific mutant alleles, they were able to reduce saturated fatty acids in high oleic acid seeds. Overall, they identified allele combinations that met the target fatty acid profiles and were stable across different environments.
