The lens of this study was to evaluate varieties of roots of yucca (Manihot Escu/enta) with the purpose of determining the variety that is ideal for the production of ethanol, since this one root only takes advantage as product of survival for the peasant ó it is commercialized as root, and little is what it transforms of this one into other products that have an added value and could be beneficia! for the producer or enrich the productive chain. One used for it five local varieties that are: "Huanuqueña", "Enana", "Amarilla", "Señorita", and "Huangana Amarilla". The study divided in three stages; first to determine the variety that has major performance in starch, then it was continued by the second stage, the relation determined pHconcentration of starch to carry out the acid hydrolysis, for which chose a variety of starch at random, and with this to determine the ideal parameters of operation. lt put in bain-marie for five hours and a half on 95 oc with HCI 12N. Determined this, it followed with the last stage, the hydrolysis and fermentation of five varieties, using for the fermentation a pure strain of Saccharomyces cereviseae MIT - L51, yielded by the Laboratory of Microbiology of the National University of Trujillo; on having completed the fermentation the quantity of alcohol was evaluated obtained, for the method of microdiffusion. The stage of fermentation was realized in an incubator to a temperature of 30 °C and a pH of 4.5 in order that conditions exist standard in this process. Across an analysis of ANVA and Tukey in the different stages realized in a program computacional INFOSTAT decided that the "Amarilla" variety is ideal in agreement to the performance in starch and ethanol on other studied varieties.
