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.
Claims10
A method of obtaining soybean germplasm, comprising the steps of:
- a) identifying at least a first polymorphism in a soybean plant genomic region within a Fad3-1b allele conferring decreased linolenic acid content, wherein the first polymorphism comprises a polymorphism at a position in the Fad3-1b gene sequence corresponding to nucleotide 2021 of SEQ ID NO:1;
- b) assaying soybean plants for the presence of the polymorphism;
- and
- c) selecting at least a first soybean plant comprising the polymorphism.
A method of plant breeding comprising the steps of:
- a) assaying soybean plants for the presence of at least a first polymorphism in a soybean plant genomic region of a Fad3-1b allele conferring decreased linolenic acid content wherein the first polymorphism comprises a polymorphism at a position in the Fad3-1b gene sequence corresponding to nucleotide 2021 of SEQ ID NO:1;
- b) selecting at least a first soybean plant comprising the polymorphism;
- and
- c) crossing the first soybean plant to a second soybean plant to produce progeny plants comprising the polymorphism.
