Abstract: Rare soybean (Glycine max) germplasm with typical variations in subunit composition was tested to analysis the effect of 7S globulin subunit composition on soybean nutrient quality. The results showed that the 7S globulin subunit composition affected the contents of protein, fat, 5 fatty acids, and 15 amino acids (especially, the greatest effect on Cys) excluding Val and Ile. There were significant differences between the null types with different 7S globulin subunit compositions and their corresponding normal types on the contents oleic acid, linoleic, and stearic acid.
