DEVELOPMENT OF MG00, 0 AND I SOYBEAN GERMPLASM HIGH OLEIC ACID, LOW SATURATED FATTY ACIDS AND LOW LINOLENIC ACID WITH GOOD AGRONOMIC QUALITY
Soybean and Nitrogen Fixation Research
2012 Annual Report
1a.Objectives (from AD-416):
Lines with low linolenic acid (<3%), and/or less than 7% saturated fatty acids (16:0 + 18:0) will be developed for maturity groups 00, 0 and I and released if competitive in performance.
1b.Approach (from AD-416):
Utilize classical methods of plant breeding and molecular tools available to accelerate the development of breeding material with higher oil concentration and improved fatty acid profiles.
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 6645-21220-012-44S and has been active only since April 1, 2012. Yield trials of advanced lines with modified fatty acid composition have been planted. A high yielding low linolenic line is being used as the recurrent parent in a marker assisted backcrossing program that has high oleic lines as the donor parents. High oil lines are being evaluated in yield trials.
