Soybean is one of the most economically important grain crops. As the
source of plant protein and vegetable oil, it is widely used as food and
industrial crop. Quality of soybean oil is determined by fatty acid (FA)
composition. Biochemical variation of different varieties significantly
facilitates genetic screening of kernel traits and grain quality attributes, thus
leading to one of the most important breeding strategies - improvement of
the grain composition. The main objective of this work was to evaluate
whole kernel biochemical composition of eight soybean varieties and eight
lines from different breeding programs. Phytochemical characterization was
conducted for total protein and oil content, as well as for fatty acids content
(e.g. palmitic, stearic, oleic, linoleic and linolenic acid). According to
Kjedahl method, total protein content ranged from 37.01% to 39.91%. The
obtained results showed that the lowest and the highest values for oil content
were 19.00% and 2...1.34%, respectively. Gas Chromatography/Flame
Ionization Detector (GC-FID) was used for FA quantification and
determination. The most abundant FA was linoleic acid with a range from
47.45 to 55.7 g/100g, followed by oleic acid with detected rage from 22.59
to 29.07 g/100g of total FA content. Palmitic, linolenic and stearic FA
showed a significantly lower level varied from 9.57 to 11.51 g/100g, 5.42 to
7.18 g/100g and 3.73 to 5.86 g/100g, respectively. This variability observed
in kernel quality among soybean genotypes can provide valuable information
for future breeding.
