Both linoleic and linolenic acids are of great value from a nutritional point of view, but they are highly susceptible to oxidation, which reduces the shelf life of the oils and also yields oxidation products with detrimental effects on human health (McVetty and Scarth, 2002).
Genetically modified seeds address the concerns pertaining to the amount of linolenic acids and free fatty acids in oils and offer many advantages such as high yield, better product shelf life, and a decreased usage of crop protection chemicals," explains Technical Insights Research Analyst Kasturi Nadkarny.
The germplasm line's increased oleic acid level also correlates to a decrease in polyunsaturated fatty acids (PUFAs), such as linoleic and linolenic acids, that cause off-odors and which break down when oxidized during aging or frying.

The objectives of this study were to determine the inheritance and interaction of the altered fatty acid levels in RG3 and RG1, and the effects of altered levels of palmitic and linolenic acids on other fatty acids.
Studies conducted with common cultivars under extreme temperature conditions have indicated that seeds from soybean plants exposed to high daily temperatures have reduced linoleic and linolenic acids and increased oleic acid contents (Howell and Collins, 1957; Wolf et al.
The genetic relationship of the loci for high oleic and low linolenic acids in soybean is still unknown, although studies on relationships of low linolenic acid with low and high palmitic acid in soybean (Nickell et al.
High oleic acid content typically arises through decreased desaturation to linoleic and linolenic acids (Wilson, 1991).
