Resumen

© Facultad de Ciencias Bioĺgicas UNMSM. The anatomical characterization of the development of the storage root was carried out in three of sweet potato genotypes. In the initial stages differences were found in the development of the primary xylern, including the formation of a medullary parenchyma. The secondary cambial activity contributed to a great extent to the development of the storage parenchyma, determined a differential arrangement of the vascular bundles. Also simple and compound starch grains were found and the dimensions of the first were associated to the bigger size of the parenchyma. One of the genotypes presented high values in the thickness of the phellem and starch grains (123,9 j.im and 29,5 urn respectively). These characteristics are suggested as parameters in the selection of sweet potato genotypes.
