Resumo: | Studies on the determination of genetic divergence among genotypes are important tools in breeding programs, contributing to the identification of parents with considerable productive potential. However, little is known about the combinatorial capacity of sweet potato (Ipomoea batatas) accessions and its adaptation to the different regions of Brazil. The objective of this study was to evaluate the morpho-agronomic traits from 102 sweet potato accessions from the Germplasm Bank of Embrapa Hortaliças. The experiment was laid out as an augmented block design comprised of 102 treatments. Nineteen above ground traits were measured using descriptors for the respective parts. Estimated values of broad sense heritability were high for the traits mean branch length (95.75%), immature leaf color (85.06%), and predominant branch color (90.57%). Coefficients of environmental variation were below 30.00% for all variables, except for branch weight (51.62%). The 102 clones analyzed presented broad genetic variability for the different traits evaluated, especially for branch weight, and branch length, and mature leaf color. |

No entanto, pouco ainda se sabe sobre a capacidade combinatória de acessos de batata-doce (Ipomoea batatas) e sobre a adaptação a diferentes regiões do Brasil. O objetivo deste trabalho foi avaliar características agronômicas de 102 acessos de batata-doce mantidos no Banco de Germoplasma da Embrapa Hortaliças. O experimento foi instalado utilizando o delineamento em blocos aumentados, com 102 tratamentos. Foram mensuradas 19 características da parte aérea utilizando-se descritores das respectivas partes. Os valores das estimativas de herdabilidade no sentido amplo foram altos para as características comprimento médio das ramas (95,75%), cor da folha imatura (85,06%) e cor predominante da rama (90,57%). Os coeficientes de variação foram inferiores a 30 % para todas as variáveis, exceto para peso das ramas (51.62%). Os 102 clones analisados apresentaram ampla variabilidade genética para as diferentes características avaliadas, principalmente para peso das ramas, comprimento das ramas e cor da folha madura.EDUFU2019-10-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/4243410.14393/BJ-v35n6a2019-42434Bioscience Journal ; Vol. 35 No. 6 (2019): Nov./Dec.; 1708-1717Bioscience Journal ; v. 35 n. 6 (2019): Nov./Dec.; 1708-17171981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/42434/27451Brazil; ContemporaryCopyright (c) 2019 Rosa maria de Deus de Sousa, José Ricardo Peixoto, Geovani Bernardo Amaro, Michelle Sousa Vilela, Paula Andrea Osorio Carmonahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessde Sousa, Rosa maria de DeusPeixoto, José Ricardo Amaro, Geovani Bernardo Vilela, Michelle SousaCarmona, Paula Andrea Osorio2022-01-19T13:11:46Zoai:ojs.www.seer.ufu.br:article/42434Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-01-19T13:11:46Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
