Native seeds should be studied and appreciated as they can contribute to the improvement of production, trade and supply aspects of family farmers, and breeding programs. The aim of the current study was to compare the physical characteristics (color and size) and the chemical composition of the grain in natura five genotypes creole red beans, grown in organic system, on the Nossa Senhora Aparecida farm, in Hi-drolândia-GO, Brazil. Completely randomized design with five treatments and four replications was employed. Caliper was used to determine the dimensions (length, height and width), Sphere II colorimeter ColorQuest to the instrumental color parameters (L*, a* e b*), and methods recommended by Association of Official Analyti-cal Chemists to the chemical composition. The Safira beans showed the greatest length and width (13.89 and 7.59 mm, respectively), in addition to greater luminosity (42.38), less reddish (3.53) and lower levels of ash and crude fiber (3.59 and 12.05 g 100 g-1, respectively). The beans Bolinha Vermelha showed the lowest di-mensions (9.1 x 4.3 x 5.7 mm), while the Vermelho Rajado beans showed lower protein (16.61 g 100 g-1) and higher ash (3.91 g 100 g-1). The bean Vermelho Rajado received the greatest levels of protein and crude fiber (18.83 and 16.45 g 100 g-1, respectively). All creole beans adapted to organic production system. Among the genotypes, beans Safira stood out for having larger and lighter in color, the beans Vermelho Rajado and Bolin-ha Vermelha dot by higher protein, beans Bolinha Vermelha by higher contents of ash and ether extract, and Vermelho Rajado the higher fiber content.
