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 15.01-18.63.2% oil and palmitic (9.47-11.49%), Stearic (3.564.23%), Arachidic (0.10-0.43%), Behenic (0.37-0.85%) as saturated fatty acids and Palmitolic (0.05-0.26%), Oleic (11.71-30.72%), Linoleic (33.93-54.79%), Linolenic (5.28-9.46%) as unsaturated fatty acids. The major minerals were observed the various ranges namely Ca (1.231.29%), Mg (0.67-0.75%), K (1.12-1.38%), N (5.82-7.05%), P (5.437.65%), S (0.69-0.97%) among the varieties. And the minor minerals were B (16.45-17.8ppm), Cu (6.29-6.81ppm), Fe (159.8-167.6ppm), Mn (108.6-100.8ppm) and Zn (76.92-100.1ppm). In comparison to the physico-chemical characteristics, BARI Soybean-5 contained maximum amount of oil and Bangladesh Soybean-4 was the best for unsaturated fatty acids. BINA Soybean-4 was the better source of total saturated fatty acid. Most of the varieties found that the major and minor minerals were not significantly difference among the varieties.
