Soybean (Glycine max (L) Merrill) presents a high level of good quality protein and lipids that consist mainly of unsaturated fatty acids. It also has considerable amounts of B complex vitamins and minerals such as iron, potassium and magnesium (Carrão-Panizzi, 1987). In addition to these good nutritional characteristics, soybean for human consumption should have a sweet, nut-like flavor, pale colored seeds (tegument, hilum and cotyledon) and suitable seed size for use as food (Destro, 1991; Vello, 1992). This research was carried out to describe the agronomic and chemical characteristics of food-type soybean genotypes for later use as cultivars or in crosses. Seventy-two soybean genotypes were used in the study, and the agronomic quantitative, qualitative and chemical traits of the grains were assessed, including mineral composition, oil, protein, carbohydrates and ash contents. The results showed that there was great genetic diversity among the genotypes studied for all the agronomic characteristics assessed. The F 82-5782 genotype was outstanding, presenting yield compatible with commercial exploitation as well as large seeds. The Mikawashima genotype presented the highest carbohydrate contents, while the Toffumame II genotype showed the greatest P contents and was also among the six genotypes that presented the greatest K, Ca, Mg, S, Zn, Mn and protein values. These genotypes can be used as cultivars or in breeding programs to solve specific problems of nutrient shortage due to genetic traits.
