The sweet potato is a culture that fits the most diverse Brazilian environmental conditions and has great potential for the production of ethanol from the use of their roots. And can be used both as food and feed.The objective was to evaluate sweet potato clones with potential for producing ethanol, starch yield and production potential of dry branches and roots.The experimental design was randomized blocks, using 60 treatments, 50 clones and 10 witnesses with three replications.Genotypes were belonging to LASPER (Research Laboratory and Production Renewable Energy). We evaluated the productivity of roots and branches, starch content and dry matter of roots and branches and resistance to soil insects.The clones 048-02, 112-07, 022-19, 048-14, 114-18, agronomically have potential for production of fuel ethanol.The clones 002-580 and 106-62 can be used in animal feed using their branches.There was no significant difference between treatments evaluated for the starch content.Witnesses had higher dry matter of roots, cultivars highlighting: Carolina Victory, Duda, and Marcela. The Barbara witnesses, Duda, Carolina Victoria and Beatrice are tolerant incidence of damage caused by soil insects.
