Varietal differences in chemical compositions of summer type soybean seeds

This study was conducted to obtain basic information for breeding materials on the chemical compositions of soybean[Glycine max (L.) Merrill] seeds. Seed dry weight, protein content, oil content, fatty acid composition, soluble sugar content and starch content were analyzed to 53 collected summer type soybean varieties. Seed dry weights of summer type soybean varieties were ranged 10.5-25.6g and protein contents of those were ranged 33.6-45.0%. Oil contents of the varieties were ranged 12.1-18.0%, and linoleic and oleic acids of those were major components in the fatty acids. Sugar contents were ranged 6.1-10.0%, and starch contents ranged 3.1-5.6% in summer type soybean varieties. Significant correlation coefficients were found among seed dry weight and chemical compositions of summer type soybean varieties.
