The invention overcomes the deficiencies of the prior art by providing methods for marker assisted selection to create plants of a soybean variety that exhibit a mid/low linolenic acid content with a commercially significant yield and an agronomically elite phenotype. The invention also provides derivatives and plant parts of these plants. Further provided by the invention are methods for the use of these plants. The invention is significant in that oil with decreased linolenic acid exhibits numerous beneficial characteristics yet prior art varieties with decreased linolenic acid also exhibited decreased yield and poor agronomic quality.
