Abstract
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.
Claims19
A plant of an agronomically elite soybean variety having a commercially significant yield and a mid/low-linolenic acid content, comprising a Fad3-1b allele and a Fad3-1c allele each of which confer decreased linolenic acid content, and wherein the Fad3-1c allele comprises:
- (i) a single nucleotide polymorphism at a position in the Fad3-1c gene sequence corresponding to nucleotide 687, 1129, 1203, 2316, 3292, 3360 or 3743 of SEQ ID NO:2;
- or (ii) a single nucleotide polymorphism at a position in the Fad3-1c promoter corresponding to nucleotide 334, 364, 385, 387, 393, 729 or 747 of SEQ ID NO:3.
