EFFECTS OF GENOTYPES ON PHYSICO-CHEMICAL CHARACTERISTICS OF SOYBEAN (Glycine max L.)

Abstract

Six varieties of Soybean were analysed to evaluate the effects of genotypes on physico-chemical characteristics. Raw soybean genotypes exhibited oil content (13.32- 17.17%) and palmitic (7.40- 10.89%), stearic (2.52- 3.78%), arachidic (0.07- 0.43%), behenic (0.31- 0.62%) as saturated fatty acids and palmitolic (0.05-0.13%), oleic (7.13-29.05%), linoleic (26.49-165.4%), linolenic (4.84-8.96%) as unsaturated fatty acids. The major minerals were observed the various ranges namely Ca (1.23-1.97%), Mg (0.66-0.77%), K (1.19-1.48%), N (5.99-6.80%), P (0.73-0.94%), S (0.26-0.33%) among the varieties. And the minor minerals were B (13.56-17.40ppm), Cu (6.36- 6.88ppm), Fe (106.7-162.8ppm), Mn (68.27-103.1ppm) and Zn (98.32- 65.95ppm). In comparison to the physico-chemical characteristics, Shohag contained maximum amount of oil and Bangladesh Soybean-4 was the best for total percentage of unsaturated fatty acids, whereas Shohag was the good source of total saturated fatty acid. Most of the varieties found that the major and minor minerals were more or less significantly difference among the varieties.
