Common bean was originated from the Americas and has shown enormous socioeconomic importance as the main source of feeding in many countries. Due to adoption of technologies such as irrigation, the bean has been cultivated at different times throughout the year, however, the lack of cultivars adapted to the climatic conditions of the Cerrado of Tocantins has limited obtaining best yields at the time of the season. Thus, the aim of this work was to evaluate the performance of common bean genotypes in three cropping years in cerrado soils. The experiments were conducted in the field at the Experimental Station of the Federal University of Tocantins in the dry season of the years 2010, 2011 and 2012. The experimental design was a randomized block with four replications in a 8 x 3 factorial, consisting of eight genotypes and three years. The evaluated characteristics were plant height, the first pod height, number of pods per plant, number of seeds per pod, weight of hundred grains and grain yield. The Princesa genotype stood out with yields above 3,000 kg ha-1 in more than a year of cultivation, demonstrating its potential for cropping systems in the State of Tocantins. The genotype BRS-Esplendor was the only genotype that showed stable behavior for all traits.
