Abstract In previous works, a method was developed for the differentiation at the foliar level of the response of banana plants to Fusarium race 1 wilt, which constitutes a useful tool to increase the efficiency of resistance selection in ex vitro conditions. The objective of this work was to evaluate resistance to this disease in new banana clones using the evaluation method mentioned. For this, six moments of evaluation were made; and ten plants of each selected line of the irradiated ‘Zanzíbar’ clone were used. The results showed that the plants of the evaluated lines of the irradiated ‘Zanzíbar’ clone indicate that they are promising materials for genetic improvement in the crop aimed at resistance to this disease. On the other hand, a response to selection was obtained in a short time (48 hours), as well as evaluating the lines selected from large populations of plants (60 plants) with the exclusion of other organisms; and the control of environmental conditions that could interfere with the results obtained. However, it is necessary to continue additional studies in the field to confirm the resistance in the evaluated lines.
