In order to obtain the shoots in laboratory conditions, it was necessary to prepare the sweet potato tubers and plant them, ensuring favorable conditions of temperature, light and humidity. Axial shoots from sweet potato varieties: KSP1, DK 19/1, DK 19/2, DCh 19/3, DK 19/4 and DK 19/5 were used as a source of explants for the initiation of in vitro culture. Through a single factor experiment in three repetitions, the analyzed factor was the sweet potato variety, with 6 graduations, and as a control the average values for the studied elements were established. Determinations were made on the following parameters: the formation of shoots, the number of leaves, the height of the plantlets and the weight of the fresh root. The results presented in this study highlight the possibility of obtaining sweet potato shoots and in laboratory conditions, throughout the year, with minimal costs. allowing in vitro cultivation technique to obtain in a short time a stock of healthy starting material, which can be used as planting material.
