영문 초록

The 117 soybeans seeds were collected from the nine provinces of Korea, and protein and lipid contents, and fatty acid composition levels were evaluated to investigate their relationship. The 100-seed weights of the black soybeans were varied 27.7~33.1 g, while the 100- seed weight of yellow soybeans were varied 24.6~36.6 g. Protein and lipid content of the 117 soybean seeds was 38.3% and 17.8%, respectively. Protein contents of the 59 black soybean seeds (38.6%) were significantly higher than those of the 58 yellow soybean seeds (37.9%). However, lipid contents of the black soybean seeds (17.6%) were lower than those of the yellow soybean seeds (18.1%). Linoleic and oleic acid composition levels of the 117 soybean seeds were 53.75% and 22.08%. Unsaturated fatty acid levels of soybean seeds showed a statistically significant variability among the nine provinces of Korea, however, the differences were not found in the linoleic (18:2) and oleic acid (18:1) levels. Therefore, it was considered that the significant variability of unsaturated fatty acid were mainly due to the variations of linolenic acid (18:3) level. The composition levels of linoleic, oleic, palmitic (16:0), and linolenic acid in the yellow soybean seeds were 53.43%, 22.73%, 12.23%, and 8.24%, while those of the black soybean seeds were 54.13%, 21.48%, 12.47%, and 8.31%. Obtained results suggested that fatty acid composition levels were varied and possibly influence by the phenotype of seed coat colors. Oleic acid, mono-saturated fatty acid, showed the most remarkable variability between yellow and black soybean seeds, and the composition levels were higher in the yellow soybean seeds. Relationship between unsaturated fatty acid levels and 100-seed weights in the yellow soybean seeds showed a negative correlation (r=-0.513, P<0.01), but no relationship (r=0.154ns) was observed in the black soybean seeds.
