The use of cuban potato varieties for the production of original seed by biotechnological methods help to reduce imports by the concept of buying seed. The present study was to determine the morphological and agronomic response of cultivated in vitro plantlets of two varieties of Cuban potato. Grettel and Yara varieties from breeding program of the National Institute of Agricultural Sciences (INCA) were used and  planted in the greenhouse. The plant height and number of stems per plant was measured. Subsequently at the time of harvest the number, weight and size of the tubers per plant were quantified. Furthermore, the form of tubers and the skin color in each variety were evaluated. As a result, to produce of original seed of two Cuban varieties included in the national seed production program were gotten. The morphological differences between varieties of Cuban potato Yara and Grettel in greenhouse from in vitro plantlets were found. The Grettel variety had the highest number of tubers per plant but smaller calibre than Yara. These results allow to plan the production of original seed potatoes of two varieties by biotechnological methods
