In two moisture conditions (drought and irrigation) were evaluated six varieties of common bean (Phaseolus vulgaris L.), with a factorial randomized complete blocks. The objectives of the study was to evaluate the effect caused by drought conditions crop varieties, identify high performance and features that enable them to adapt to varying conditions of soil moisture. With the data in yields between the two humidity conditions intensity indices of drought (IIS), susceptibility to drought (ISS), relative efficiency (IER), geometric mean (GM) and percent yield losses were calculated . The results were statistically processed using the Statistica software version 8.0 for Windows, if significant differences Tukey test was applied to p<0.05. The selection based on levels ISS, MG, IER and PPR identified high yielding varieties adapted to drought and favorable moisture conditions.
