Potencial Quantitativo E Qualitativo De Genótipos Batata-Doce

Abstract

Resumo: Não há na literatura trabalhos que avaliem descritores importantes em batata-doce individualmente em ramas, raízes e em toda a planta (raízes + ramas). Esta informação detalhada é importante, pois permite a seleção dos melhores genótipos considerando a planta (raízes + ramas), tendo em vista as diferentes formas de utilização: consumo humano, animal, indústria e produção de etanol. Portanto, objetivou-se avaliar o potencial produtivo de matéria fresca, matéria seca, amido e proteína bruta em raízes, ramas e planta (ramas + raízes) de batata-doce, a fim de se identificar os genótipos superiores. Para isso, foram avaliados 40 acessos de batata-doce do banco de germoplasma da UFVJM. A produção total da batata-doce (raízes + ramas) foi alta, o que aliado a sua rusticidade e múltiplos fins realça seu grande potencial e importância. Houve grande variabilidade genética entre os acessos. Os acessos Tomba Carro 1, UFVJM (01, 28 e 40) são os mais recomendados devido as maiores produtividades de raízes, ramas e proteína bruta, sendo adequados à alimentação humana e animal. Os acessos Palmas e UFVJM (01, 04, 05, 07 e 53) podem ter maior potencial para a produção de etanol devido à maior produtividade de amido.Palavras-Chave -Ipomoea batatas (L.)

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.

Selection of superior sweet potato genotypes for human consumption via mixed models

“…These first five genotypes were superior to the performance of the best commercial cultivar for the commercial root yield trait. For the traits general shape and commercial standard, although the best average score was of the commercial cultivar Beauregard, the genotypes 2018-19-443, 2018-19-464, and 2018-36-807 showed a similar general shape, as well as the genotypes -54-1137and 2018-19-464 in commercial standard. The 2018-65-1249and 2018-54-1137 genotypes were superior to the best commercial cultivar for the root clustering trait.…”

“…Gotas pendentes formadas a partir dessas misturas foram medidas (Arrué et al, 2014). Adjuvants such as plant, mineral oils, or oil derivatives in the solution can raise the efficiency in the control of pests and diseases, since it protects the applied solution from unfavorable weather conditions, or improving the interaction between the solution and the target (Andrade Junior et al, 2010).…”
