•Clonal genotypes more drought tolerant maintained leaf water potential values with increasing water deficit in soil, under greenhouse conditions.•Clonal genotypes presented significant differences in the physiological characteristics when subjected to water deficit in the soil.•DTC clonal genotypes 7, 8, 11, 14, 15, 17, 18, 26, 40, 41 57, 61, 65 66, 70, 78, 85, 88, 91, 92, 93 and 102 were selected as drought tolerant, mainly due to the maintenance of the values of physiological traits.•Drought tolerance indices were efficient in identifying the DTC more tolerant to water deficit in the soil. |
