Therefore, the evaluation and characterization of genotypes adapted to the north of Minas Gerais are important because it enables the selection of genotypes with agronomic potential for cultivation and the integration in breeding programs. Therefore, the aim was to evaluatethe most cultivated cassava varieties in the north of Minas Gerais, in order to obtain information of genetic parameters, correlations, dissimilarity and agronomic performance. For that, 54 morpho- agronomic traits were evaluated in 6 varieties in a randomized block design with four replications. For the dissimilarity study was performed the Tocher test and hierarchical dendrogram by the UPGMA method. There was genetic variability among the varieties and prevalence of genetic effects over the environmental ones for most evaluated features. The Vassourinha variety stood out with higher roots productivity being the most recommended for cultivation. The features, net photosynthesis and transpiration rate correlated with the root productivity, making them important for breeding programs.Three groups were formed by multivariate analysis, verifying that the crossing of variety Vassourinha with Amarelinhavarietie, Ass. E.N. or Sabará can enable obtaining high genetic variability progenies.Embora as plantas de mandioca apresentem alto potencial produtivo, a produtividade nacional é baixa, principalmente em norte de Minas Gerais. Portanto, a avaliação e caracterização de genótipos adaptados ao norte de Minas Gerais são importantes porque possibilitam a seleção de genótipos com potencial de cultivo e integração em programas de melhoramento. Assim, o objetivo foi avaliar variedades de mandioca mais cultivadas no norte de Minas Gerais, a fim de obter parâmetros genéticos, correlações, dissimilaridade e desempenho agronômico. Para tanto, foram avaliados 54 caracteres morfoagronômicos em 6 variedades em delineamento de blocos casualizados com quatro repetições. Para o estudo de dissimilaridade foi realizado o teste de Tocher e dendrograma hierárquico pela UPGMA método. Houve variabilidade genética entre as variedades e prevalência de efeitos genéticos ao longo da ambientais para as características mais avaliadas. A variedade Vassourinha se destacou com raízes mais altas produtividade sendo a mais recomendada para o cultivo. As características, fotossíntese líquida e a taxa de transpiração correlacionou-se com a produtividade das raízes, tornando-as importantes para os programas de melhoramento. Três grupos foram formados por análise multivariada, verificando que o cruzamento da variedade Vassourinha com Amarelinhavarietie, Ass. E. N. ou Sabará pode possibilitar a obtenção de progênies de alta variabilidade genética.engUniversidade Federal de Minas GeraisUFMGBrasilICA - INSTITUTO DE CIÊNCIAS AGRÁRIASInternational journal of current researchMandioca - VariedadesPlantas - AnáliseGenetica vegetalCharacterization, dissimilarity and genetic parameters on cassava varietiesCaracterização, dissimilaridade e parâmetros genéticos em variedades de mandioca.info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttp://www.journalcra.com/article/characterization-dissimilarity-and-genetic-parameters-cassava-varietiesJoão Batista de Campos MenezesCândido Alves da CostaHugo César Rodrigues Moreira CatãoAlcinei Mistico AzevedoCelso Mattes de OliveiraErnane Ronie Martinsinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/40221/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALCharacterization, dissimilarity and genetic parameters on cassava varieties.pdfCharacterization, dissimilarity and genetic parameters on cassava varieties.pdfapplication/pdf195112https://repositorio.ufmg.br/bitstream/1843/40221/2/Characterization%2c%20dissimilarity%20and%20genetic%20parameters%20on%20cassava%20varieties.pdf0bbaa82265be39aaa65ba8e60cbaf4baMD521843/402212022-03-18 11:19:19.524oai:repositorio.ufmg.br:1843/40221TElDRU7vv71BIERFIERJU1RSSUJVSe+/ve+/vU8gTu+/vU8tRVhDTFVTSVZBIERPIFJFUE9TSVTvv71SSU8gSU5TVElUVUNJT05BTCBEQSBVRk1HCiAKCkNvbSBhIGFwcmVzZW50Ye+/ve+/vW8gZGVzdGEgbGljZW7vv71hLCB2b2Pvv70gKG8gYXV0b3IgKGVzKSBvdSBvIHRpdHVsYXIgZG9zIGRpcmVpdG9zIGRlIGF1dG9yKSBjb25jZWRlIGFvIFJlcG9zaXTvv71yaW8gSW5zdGl0dWNpb25hbCBkYSBVRk1HIChSSS1VRk1HKSBvIGRpcmVpdG8gbu+/vW8gZXhjbHVzaXZvIGUgaXJyZXZvZ++/vXZlbCBkZSByZXByb2R1emlyIGUvb3UgZGlzdHJpYnVpciBhIHN1YSBwdWJsaWNh77+977+9byAoaW5jbHVpbmRvIG8gcmVzdW1vKSBwb3IgdG9kbyBvIG11bmRvIG5vIGZvcm1hdG8gaW1wcmVzc28gZSBlbGV0cu+/vW5pY28gZSBlbSBxdWFscXVlciBtZWlvLCBpbmNsdWluZG8gb3MgZm9ybWF0b3Mg77+9dWRpbyBvdSB277+9ZGVvLgoKVm9j77+9IGRlY2xhcmEgcXVlIGNvbmhlY2UgYSBwb2zvv710aWNhIGRlIGNvcHlyaWdodCBkYSBlZGl0b3JhIGRvIHNldSBkb2N1bWVudG8gZSBxdWUgY29uaGVjZSBlIGFjZWl0YSBhcyBEaXJldHJpemVzIGRvIFJJLVVGTUcuCgpWb2Pvv70gY29uY29yZGEgcXVlIG8gUmVwb3NpdO+/vXJpbyBJbnN0aXR1Y2lvbmFsIGRhIFVGTUcgcG9kZSwgc2VtIGFsdGVyYXIgbyBjb250Ze+/vWRvLCB0cmFuc3BvciBhIHN1YSBwdWJsaWNh77+977+9byBwYXJhIHF1YWxxdWVyIG1laW8gb3UgZm9ybWF0byBwYXJhIGZpbnMgZGUgcHJlc2VydmHvv73vv71vLgoKVm9j77+9IHRhbWLvv71tIGNvbmNvcmRhIHF1ZSBvIFJlcG9zaXTvv71yaW8gSW5zdGl0dWNpb25hbCBkYSBVRk1HIHBvZGUgbWFudGVyIG1haXMgZGUgdW1hIGPvv71waWEgZGUgc3VhIHB1YmxpY2Hvv73vv71vIHBhcmEgZmlucyBkZSBzZWd1cmFu77+9YSwgYmFjay11cCBlIHByZXNlcnZh77+977+9by4KClZvY++/vSBkZWNsYXJhIHF1ZSBhIHN1YSBwdWJsaWNh77+977+9byDvv70gb3JpZ2luYWwgZSBxdWUgdm9j77+9IHRlbSBvIHBvZGVyIGRlIGNvbmNlZGVyIG9zIGRpcmVpdG9zIGNvbnRpZG9zIG5lc3RhIGxpY2Vu77+9YS4gVm9j77+9IHRhbWLvv71tIGRlY2xhcmEgcXVlIG8gZGVw77+9c2l0byBkZSBzdWEgcHVibGljYe+/ve+/vW8gbu+/vW8sIHF1ZSBzZWphIGRlIHNldSBjb25oZWNpbWVudG8sIGluZnJpbmdlIGRpcmVpdG9zIGF1dG9yYWlzIGRlIG5pbmd177+9bS4KCkNhc28gYSBzdWEgcHVibGljYe+/ve+/vW8gY29udGVuaGEgbWF0ZXJpYWwgcXVlIHZvY++/vSBu77+9byBwb3NzdWkgYSB0aXR1bGFyaWRhZGUgZG9zIGRpcmVpdG9zIGF1dG9yYWlzLCB2b2Pvv70gZGVjbGFyYSBxdWUgb2J0ZXZlIGEgcGVybWlzc++/vW8gaXJyZXN0cml0YSBkbyBkZXRlbnRvciBkb3MgZGlyZWl0b3MgYXV0b3JhaXMgcGFyYSBjb25jZWRlciBhbyBSZXBvc2l077+9cmlvIEluc3RpdHVjaW9uYWwgZGEgVUZNRyBvcyBkaXJlaXRvcyBhcHJlc2VudGFkb3MgbmVzdGEgbGljZW7vv71hLCBlIHF1ZSBlc3NlIG1hdGVyaWFsIGRlIHByb3ByaWVkYWRlIGRlIHRlcmNlaXJvcyBlc3Tvv70gY2xhcmFtZW50ZSBpZGVudGlmaWNhZG8gZSByZWNvbmhlY2lkbyBubyB0ZXh0byBvdSBubyBjb250Ze+/vWRvIGRhIHB1YmxpY2Hvv73vv71vIG9yYSBkZXBvc2l0YWRhLgoKQ0FTTyBBIFBVQkxJQ0Hvv73vv71PIE9SQSBERVBPU0lUQURBIFRFTkhBIFNJRE8gUkVTVUxUQURPIERFIFVNIFBBVFJPQ++/vU5JTyBPVSBBUE9JTyBERSBVTUEgQUfvv71OQ0lBIERFIEZPTUVOVE8gT1UgT1VUUk8gT1JHQU5JU01PLCBWT0Pvv70gREVDTEFSQSBRVUUgUkVTUEVJVE9VIFRPRE9TIEUgUVVBSVNRVUVSIERJUkVJVE9TIERFIFJFVklT77+9TyBDT01PIFRBTULvv71NIEFTIERFTUFJUyBPQlJJR0Hvv73vv71FUyBFWElHSURBUyBQT1IgQ09OVFJBVE8gT1UgQUNPUkRPLgoKTyBSZXBvc2l077+9cmlvIEluc3RpdHVjaW9uYWwgZGEgVUZNRyBzZSBjb21wcm9tZXRlIGEgaWRlbnRpZmljYXIgY2xhcmFtZW50ZSBvIHNldSBub21lKHMpIG91IG8ocykgbm9tZXMocykgZG8ocykgZGV0ZW50b3IoZXMpIGRvcyBkaXJlaXRvcyBhdXRvcmFpcyBkYSBwdWJsaWNh77+977+9bywgZSBu77+9byBmYXLvv70gcXVhbHF1ZXIgYWx0ZXJh77+977+9bywgYWzvv71tIGRhcXVlbGFzIGNvbmNlZGlkYXMgcG9yIGVzdGEgbGljZW7vv71hLgo=Repositório InstitucionalPUBhttps://repositorio.ufmg.br/oaiopendoar:2022-03-18T14:19:19Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false
