Conteúdo: | The cassava clone'Senorita' is a local ecotype widely cltivated in the cassava-growing regions of Cuba, occupying large areas of different edapho-climatic conditions. Yield losses due to physiological or genetic problems have increased due to exposure of the crop to various stress factors in the yield  and subsequent vegetative propagation. The clone has been propagated for more than 30 years without being reiuvenated. Using meristem micropagation techniques, it has been possible to create a program to recover the yield stability of 'Senorita'. A comparative study was carried out using plants obtained from meristem culture. An invrease in yield of commercial tuber roots up to 15% was obtained using meristem culture. The results suggest that there is a need touse meristem culture to maintain the yiedls of this vegetatively propagated crop.
