Research Project: DEVELOPMENT OF IMPROVED SOYBEAN LINES WITH LOW LINOLENIC OR HIGH OLEIC ACID

Location: Soybean and Nitrogen Fixation Research

2012 Annual Report


1a.Objectives (from AD-416):
Conduct genetic research leading to increased knowledge of soybean oil for applied plant breeding improvements in oil quality and quantity.


1b.Approach (from AD-416):
Utilize classical methods of plant breeding, gas chromatography of fatty acid methyl esters, and single nucleotide polymorphisms (SNPs) for molecular marker assisted selection (MAS) for soybean oil improvement.


3.Progress Report:

This project is related to Objective 2 of the in-house project: To discover novel genes/alleles in soybean for seed composition, determine their inheritance, determine genomic location, transfer to adapted germplasm, and release.

This new research project is a continuation of the research project 6645-21220-012-42S and has been active only since April 1, 2012. Yield trials of advanced lines with modified fatty acid composition have been planted. Additional crosses have been made to incorporate the low linolenic and high oleic traits into advanced breeding lines. Phenotypic and genotypic data of a mapping population developed to identify oil and protein QTL is being analyzed.
