Soybeans having low linolenic acid content and method of production

Abstract

Methods are described for the production of soybean varieties and lines exhibiting linolenic acid contents of less than about 2.5% of the total fatty acid composition as determined by gas chromatography, preferably less than about 2.2% and, more preferably, less than about 1.9%, and in one aspect of the invention, soybean varieties and lines having the low linolenic acid characteristic and a stearic acid content of at least 20%, preferably at least 25%, and, more preferably, at least about 30%, and in a further aspect, soybean varieties and lines having the low linolenic acid content and a palmitic acid content of at least 11%, more preferably at least about 13 or 14%. In accordance with still further aspects of this invention, soybean lines are provided which exhibit a low linolenic acid content and an oleic acid content of at least about 60% of the total fatty acid composition, such lines may, if desired, also contain a palmitic acid content of less than about 6.0% and/or a stearic acid content of less than about 3.5%. There is also disclosed soybean lines having low linolenic acid contents and a palmitic acid content of less than about 5.0%, preferably less than about 4.0%.
