Interpretive Summary:

Technical Abstract: The polysaccharide composition and content of soybean seed were determined in 14 genotypes adapted to Minnesota. The objective was to investigate the genotypic and environmental variation in seed pectin, hemicellulose, and cellulose content. Whole seeds grown at four locations for 2 years were ground, and the polysaccharides analyzed using the total dietary fiber method to determine monosaccharide content of the polysaccharides. Rhamnose, arabinose, mannose, xylose, galactose, glucose, and uronic acids differed significantly among genotypes (p<0.05). Xylose, mannose, galactose, glucose, and uronic acids differed significantly by location (p<0.05). Glucose content in polysaccharides was correlated to protein content. No correlation was found between the other polysaccharide components and protein or oil concentration. Seed weight was correlated to cellulose, hemicellulose, pectin/cellulose, and protein content.
