Genetic variability of 32 inbred special grains bean lines was investigated for grain yield, mass of 100 grains, cooking time, and mineral concentrations in grains, and Z index was used for selection of superior lines in most of the characters. IAC Cen-tauro, IAC Galante, Xamego, Ouro Branco, Montcalm, and Hooter lines presented high yield grain, short cooking time (less than 24 min), and high potassium (>14 g kg-1 dry matter [DM]), calcium (>1.42 g kg-1 DM), iron (>97.60 mg kg-1 DM), zinc (>29.05 mg kg-1 DM) and copper (>8.67 mg kg-1 DM) concentrations, and their dietary use is therefore recommended. Cal-96 line presents higher Z index for grain yield and for the most of the minerals, and its use is recommended for crosses for the development of superior lines.
