Comparison of a high oleic acid soybean line to cultivated cultivars for seed yield, protein and oil concentrations

An increased oleic acid concentration improves the nutritional value and oxidative stability of soybean seed oil. High oleic acid soybean cultivars should have desirable agronomic and compositional traits such as a high seed yield, protein and oil concentrations compared to popular, commercially grown cultivars. A high oleic acid soybean line, JD11-0070, was compared to three commercial soybean cultivars in four Korean environments for seed yield, protein and oil concentrations. JD11-0070 had a stable oleic acid concentration across environments, averaging approximately 79 % at each location. In addition, there were no significant differences between JD11-0070 and the other cultivars for seed yield or protein concentration, although JD11-0070 had a lower oil concentration than the other cultivars. Thus, high oleic acid soybean lines such as JD11-0070 can be developed with similar yields and favorable seed protein and oil quality compared to commercially grown soybeans. In addition, use of high oleic oil from this line could contribute to human health, and industrial applications.
