Abstract

Aim: Soybean is a strategic crop plant grown to obtain edible oil and forage. Oil content and fatty acid composition of oilseeds are important consideration for breeding programs. This study was conducted to determinate fatty acid compositions of some soybean varieties grown in both main and double cropping system at the University of Cukurova, Turkey in 2013 and 2014 growing seasons.

 

Methodology: The experiment was designed in a Randomized Complete Block with three replications. Soybean varieties Atakisi, Arısoy, Cinsoy, Adasoy, Ilksoy, Turksoy, Ataem-7, Sa 88, S 4240, Blaze and Nova (maturity group III and IV) were used as a plant material. Oil content and fatty acid (palmitic, stearic, oleic, linoleic and linolenic acids) compositions of soybean varieties were investigated.

 

Results: According to a two-year average, the fatty acid composition of soybean varieties ranged from 10.59-12.09% for palmitic acid, 3.11-4.52% for stearic acid, 27.02-34.09% for oleic acid, 44.51-51.80% for linoleic, and 4.44-5.61% for linolenic acid in main cropped soybean. In double cropped soybean, the fatty acid composition (two-year average) of the tested varieties ranged from 10.76-12.23% for palmitic acid, 3.94-4.87% for stearic acid, 22.69-29.51% for oleic acid, 48.40-54.14% for linoleic and 5.41-6.62% for linolenic, respectively.    

 

Interpretation: The oil and oleic acid content was found higher in main cropped than double cropped growing season, but the linoleic acid content was higher in double cropped than in main cropped growing seasons.
