The value of cultivation and use (VCU) tests are required for registration of new cultivars. The rules for conducting VCU tests were very restrictive as they require many tests to register the new cultivar of common bean (Phaseolus vulgaris). The standard rule has been relaxed since 2010 and was considers the regionalization of Brazil in edaphoclimatic regions (ECR). Thus, ten environments are currently accepted for regions I (South) and II (Central), and six environments for Region III (Northeast). Of which three environments are required per sowing season for the season in which the cultivar is to be indicated. The aim was to validate the number of environments for cultivar recommendation by computational simulation in three edaphoclimatic regions (ECR) in Brazil using field data from a 17-year period. The algorithm was created to simulate scenarios with different numbers of environments randomly sampled and to compares the genotype classified in the simulated scenarios to the ones classified in the complete multi-trial analysis. Components of variance, selective accuracy (SA), and relative grain yield were estimated for each simulated scenario. We find a high percentage of matches between the best-classified genotypes in the simulated scenarios with fewer environments when we compare to the complete analysis. The percentage of matches rises as the number of environments increases. However, after 90% of SA is achieved the increase of the environments doesn?t necessary. Thus, eight environments for ECR1 and ECR2 and six for ECR3 are in the mean point of the increase rate and are above 90% of SA. This sample size is adequate for common bean cultivar recommendations. Thus, it is concluded that the number of environments currently accepted for registration of new cultivars is capable of indicating the superior genotypes.
