Potencial quantitativo e qualitativo de genótipos batata-doce

Abstract

There are no studies in the literature that evaluate important traits in sweet potatoes individually in branches, roots and the whole plant (roots + branches). This detailed information is important because it allows the selection of the best genotypes considering the plant (roots + branches), taking into account the different uses: food, feed, industry and ethanol production. Therefore, this study aimed to evaluate the production potential of fresh weight, dry matter, crude protein and starch in roots, branches and plant (branches + roots) of sweet potatoes, in order to identify superior genotypes. For this, we evaluated 40 sweet potato accessions of germplasm bank of UFVJM. The total production of sweet potatoes (roots + hamas) was high, which combined with its rusticity and multipurpose highlights its great potential and importance. There was great genetic variability among accessions. The Tomba Carro 1, UFVJM (01, 28 and 40) are the most recommended because of the higher yields of roots, branches and crude protein, being suitable for human and animal consumption. The Palma and UFVJM (01, 04, 05 07 and 53) accesses may have greater potential for ethanol production due to the high starch yield.
