Abstract
At present there are no drought-tolerant sweet potato clones available in Cuba, which make it possible to extend the planting period, which is a very important problem. The objective of the present research was to evaluate the Cuban germplasm bank of sweet potato under drought conditions, with the purpose of to determine sweet potato clones that possess genetic characteristics of tolerance to the water stress by drought. The experiment was developed at Research Institute of Tropical Root and Tuber Crops (INIVIT). Genotypesthat died 15 days after planting were 33, representing 5.4 %; those who died in the course of the work were 124, accounting for 20.4 % and genotypes with yields greater than 17.5 t ha-1 were five, accounting for 0.9 % of the total.
