Stress caused by drought affects food crops, such as common bean (Phaseolus vulgaris L.). The objective of this work was to determine the response in the greenhouse of black grain common beans lines in stress conditions for irrigation to pre-flowering. Four possible black grain mutant lines were evaluated supporting two treatments: application of irrigation considering the water requirements of the crop and the second, application of irrigation to pre-flowering. The sowing and the attention to the crop were carried out, with the indications established in the technical instructions. Ten plants were randomly selected in each treatment and evaluated: length of the roots/plants (cm), number of legumes/plant, number of grains/legumes and weight of 100 seeds (g). As a result, the lines showed the highest values of root length in the conditions of irrigation application to pre-flowering. In the rest of the variables evaluated, the lines showed a similar response in two treatments. This response indicated they have a certain tolerance to stress conditions.
