Para mejorar la eficiencia de regeneraci?n en dos variedades africanas de camote (Tanzania y Wagabolige) se prob? un protocolo v?a organog?nesis de dos fases en Tanzania y de dos, tres y cuatro fases en Wagabolige. La primera fase, en ambas variedades, consisti? en el mantenimiento de los explantes en un medio con auxinas y las siguientes, con citoquininas. Se prob? tres tipos de explantes: hojas con peciolo, peciolos y ra?ces. Todos los regenerantes fueron obtenidos a partir de hojas con peciolo. Los brotes emergentes fueron de apariencia normal y anormal. Se logr? resultados favorables al trabajar con bajas concentraciones de 2,4-D y en Tanzania, al suplementar AG3 a la primera etapa, se increment? la frecuencia de regeneraci?n de brotes normales; sin embargo, ambas variedades presentaron un bajo ?ndice de regeneraci?n: 3.33% en Tanzania y 1.46% en Wagabolige.To improve the regeneration efficiency of two sweetpotato African varieties (Tanzania and Wagabolige), a two-stage organogenesis regeneration protocol was tested in Tanzania; while a two, three, four-stages was tested in Wagabolige. The first stage, in both varieties, maintained the explants in a medium supplemented with auxines, and the next stages, with cytokinines. Three different explants were tested: leaves with petiole, petioles and roots. All shoots came from leaves with petioles. Shoots presented normal or anomalous morphology. The best results were obtained working with low concentrantions of 2,4-D. For Tanzania, the addition of GA3 in the first stage was found to increase normal shoot frequency, nevertheless both varieties showed low regeneration efficiencies: 3.33% in Tanzania, and 1.46% in Wagabolige.
