With 12 Vicia faba L. varieties of different genotypes as the research ma- terials, the contents of 9 kinds of quality factors of protein, fat, free amino acid as well as beneficial mineral elements were analyzed with the aim to provide the nec- essary theoretical basis for the selection of new varieties of high quality faba beans. The results showed that in the faba beans of different genotypes, the protein content ranged from 27.9% to 31.2%, fat content of 1.2-1.4%, tannin content of 4 700-5 280 mg/kg, iron content of 47.45-67.15 mgJkg, calcium content of 571.30-1 397.22 mg/kg, zinc content of 47.34-66.10 mg/kg, potassium content of 1.09-1.38%, and selenium content ranged from 0.031 mg/kg to 0.064 mg/kg. There were significant differences in the contents of different free amino acids between different genotypes, and the total free amino acid content was between 1.062% and 0.915%.
